This SpongeBob Tower Defense tier list is built for the post-Update 24 meta in May 2026, with the Exotic rarity tier now in the game (Mega-Hydra Karen leading the pack), boss battle units like Lion Fish and Gladiator Patrick added, and the meta shifting hard around the new SpongeHenge / Dream Gary / Cyborg Plankton secret tier.
Here’s what’s inside:
- Every unit ranked from S+ down to D tier
- Why SpongeHenge is the single best unit in the game
- The Exotic rarity tier and how it changes endgame
- Free units worth keeping vs ones you should fuse for materials
- Trait recommendations that actually amplify your top picks
Quick context: SpongeBob Tower Defense (often shortened to SpongeBob TD or SBTD) is a Roblox tower defense by GG Studios where you deploy units from the SpongeBob universe against waves of enemies. The unit pool keeps growing — every update adds new characters, fuse mechanics, and rarity tiers — and a tier list from a few months ago is meaningfully out of date.

How this tier list ranks units in May 2026
A couple of things to set up before the rankings.
First, you can only deploy up to 6 units at once (depending on your player level). So tier lists matter more in this game than in most TDs because you literally can’t field your entire roster — every unit slot is a tradeoff.
Second, units have unique attacks and mechanics that can make a higher-tier rarity less valuable than a lower-tier one. Handsome Squidward, Slappy Laszlo, and Garry can slow enemies. Princess Mindy and Flying Dutchman have line AoE attacks that are stupid effective on map corners. So pure rarity isn’t the whole story — placement and synergy matter.
Third, this is built around active gameplay (story acts + endless mode) rather than purely cheese tactics. Some units are theoretical S-tier in specific exploit setups but bench-warmers in normal play. I’m ranking based on what actually carries clears, not edge cases.
The tiers run S+ through D. S+ is reserved for game-defining picks. Below D is just units I wouldn’t recommend building, and there are too many to bother listing.
S+ Tier: The seven units defining the meta
These are the units everyone is either trying to roll or trying to fuse up. If you want to clear endgame story content and survive deep into Endless mode, you build around these.
| Unit | Tier | Rarity | Why It’s Here |
|---|---|---|---|
| Mega-Hydra Karen | S+ | Exotic | New Exotic top-tier, defines current meta |
| SpongeHenge | S+ | Secret | Full AoE attacks clear waves solo |
| Dream Gary | S+ | Secret | Massive DPS + enemy slow, anti-fast-mob meta |
| Cyborg Plankton | S+ | Secret | Highest Pierce DPS in the game |
| Hibernation Sandy | S+ | Mythic | High damage + strong utility |
| Captain Magma | S+ | Mythic | Powerful firebeam attack, AoE flame damage |
| GG Rock SpongeBob | S+ | Mythic | Blue ray guitar attack, excellent line DPS |
Mega-Hydra Karen is the new Exotic rarity king. The Exotic tier was added relatively recently and represents the new pinnacle of SpongeBob TD power. Her kit combines high damage, multi-target attacks, and utility that no Mythic can match. If she’s available on a banner you can pull, that’s the priority.
SpongeHenge held the “best unit in the game” slot before Exotic rarity dropped, and even now he’s arguably tied with Mega-Hydra Karen for general use. Full AoE attacks mean he hits everything in his range simultaneously — combine that with his damage scaling and he can solo-clear early waves while your other units are still cooling down from deployment.
Dream Gary is the anti-fast-mob meta. His DPS is comparable to other S+ units, but his slow effect on enemies is what makes him irreplaceable. Endless mode mobs scale into ridiculous speed numbers fast, and Dream Gary keeps them in your DPS window long enough for the rest of your team to kill them.
Cyborg Plankton is the Pierce DPS champion. Pierce damage ignores enemy armor, which becomes critical against the heavily-armored bosses that show up in Act 5+ and Endless mode 30+. No other unit pierces as efficiently per cost.
I learned the hard way that a “balanced” team without one of these S+ units bricks at Endless wave 25-30 reliably. Below S+ tier, your DPS ceiling caps out before the enemy HP scaling does. You need at least one S+ unit on your team for serious endgame.
S Tier: The reliable workhorses
These are the units I see in basically every endgame team that doesn’t have S+ rolls. Excellent on their own, even better when paired with S+ carries.
| Unit | Tier | Rarity | Why It’s Here |
|---|---|---|---|
| SpongeGar | S+ | Mythic | (Listed in S+ above — moving to S for variety) |
| Miss Appear | S | Legendary | Top Legendary, great damage + range |
| Snow Mollusk | S | Legendary | Solid AoE Legendary, stable pick |
| The Quickster | S | Mythic | Hits large groups effectively |
| Handsome Squidward | S | Legendary | Slow + DPS combo, corner specialist |
| Lion Fish | S | Limited | New boss battle unit, excellent damage |
| Gladiator Patrick | S | Limited | Boss battle unit, strong frontline |
| Soaring Starfish | S | Limited | Seasonal event unit, holds up |
| Princess Mindy | S | Mythic | Line AoE perfect for corners |
| Flying Dutchman | S | Legendary | Line AoE + range, ghost-themed |
The Mythic tier is where most account-defining picks sit. The Quickster specifically excels at large group clears, which makes him a critical supplement to single-target Mythics like Captain Magma. Pair Quickster + Captain Magma and you’re handling both swarm and elite enemies.
Handsome Squidward is the unit I see most argued about. He’s “only” Legendary rarity but his slow + DPS combo on map corners punches well above his rarity. Multiple guides put him in S or A+, and I’d lean S because corner placement is so common across maps. If a map doesn’t favor corner units, he drops to A.
The new boss battle units (Lion Fish, Gladiator Patrick, Soaring Starfish) are all Limited rarity, which means they’re event-locked. If you missed their event windows, you’re out of luck until they cycle back. That’s the catch with the Limited tier — they’re S-tier when available but you can’t farm for them.
A Tier: Strong picks with conditions
These are units I’d happily bring to most fights but wouldn’t main-build over the S+/S options.
| Unit | Tier | Rarity | Why It’s Here |
|---|---|---|---|
| Mermaid Man SpongeBob | A+ | Epic | Outperforms his rarity, strong Epic pick |
| Slappy Laszlo | A+ | Mythic | Slow + utility, niche but excellent |
| Barnacle Boy Patrick | A+ | Epic | Carries early game through Act 10 |
| Garry | A | Legendary | Slow specialist, falls off vs armored |
| Ms. Puff | A | Legendary | Reliable DPS, no specific niche |
| DoodleBob | A | Legendary | Decent damage but single-target only |
| Tango Karen | A | Legendary | Outdated kit, can’t multi-target |
| Mr. Krabs | A | Mythic | Money mechanic helps economy |
| Squilliam | A | Mythic | Mid-range AoE, stable pick |
| Karate SpongeBob | A | Epic | Solid Epic, melee specialist |
Mermaid Man SpongeBob is the unit I’d specifically call out as overperforming his Epic rarity. He sometimes outpaces Legendary units in raw damage output. If you pull him early, build him aggressively — he carries deep into Act 4-5 before you start swapping in higher-rarity units.
Barnacle Boy Patrick is the early-game savior. He carries through the first 10 levels easily, has decent attack speed, and deploys multiple times once leveled up. Don’t bench him until you have a real Mythic replacement — he’s the best Epic for new players.
Tango Karen and DoodleBob are A-tier despite being Legendary because they can’t multi-target. Single-target Legendaries fall off in waves with multiple enemies, which is most of the late game. If you have these but no other Legendaries, build them. If you have other Legendary options, prioritize those instead.
B Tier: Situational and Early-Game Picks
| Unit | Tier | Rarity | Why It’s Here |
|---|---|---|---|
| Patrick Star | B+ | Common | Free unit, holds up early game |
| SpongeBob | B+ | Common | Free, reliable for first acts |
| Squidward | B | Common | Basic kit, falls off fast |
| Sandy | B | Rare | Early-game viable |
| Plankton (base) | B | Rare | Simple kit, gets outclassed |
| Larry | B | Rare | Niche pick, decent damage |
| Pearl | B | Rare | Mid-range damage |
| Mr. Krabs (base) | B | Rare | Money utility but low damage |
The B tier is where most of your early game lives. These units are perfectly fine for Acts 1-3 and basic farming. Don’t bench them until you have proper Epic/Legendary replacements — running B-tier units at low level is more efficient than running uninvested A-tier units.
C and D Tier: Skip or Fuse for Materials
| Unit | Tier | Rarity | Why It’s Here |
|---|---|---|---|
| Man Ray | C+ | Mythic | Surprisingly weak for Mythic, slow attacks |
| Bubble Buddy | C | Common | Niche, gets outclassed quickly |
| Mrs. Puff (base) | C | Common | Outdated kit |
| Old Man Jenkins | C | Common | Filler unit |
| Painty the Pirate | D | Common | Bench |
| Bubble Bass | D | Common | Avoid building |
Man Ray’s C+ tier is the noisiest controversy in this list. He’s Mythic rarity, which usually means strong, but his slow attacks and lower damage than expected make him underwhelming. Multiple guides flag him as the weakest Mythic in the current meta. Fuse him for materials if you pull him; don’t waste investment.
The C/D tier exists mostly as fusion fodder. If you pull duplicates of these or have spares from the gacha, fuse them into your S+ and S units instead of building them. Resource efficiency in SpongeBob TD comes from concentrating investment, not spreading it thin.
Why the Exotic rarity changed everything in 2026
Quick context for why this tier list looks different from one written even six months ago.
Exotic rarity was added to the game relatively recently and represents a new top-tier above Secret. Before Exotic dropped, Secret rarity (SpongeHenge, Dream Gary, Cyborg Plankton) was the absolute ceiling. Now Mega-Hydra Karen sits above all of them.
What this means for your account:
- If you don’t have an Exotic unit yet, your team caps out at Secret + Mythic combinations, which are still strong but no longer meta-defining
- If you have Mega-Hydra Karen, your build priorities shift — you’re playing around her kit instead of around SpongeHenge
- Pulling for Exotic units takes priority over pulling for any other rarity if you’re trying to push endgame
The introduction of Exotic also reset some Mythic tier slots. Several Mythics that used to be S-tier dropped to A-tier because they could no longer keep pace with Exotic damage scaling. Hibernation Sandy and Captain Magma held their S+ slots, but Man Ray fell off hard.
Boss Battle Units and Why They’re Limited Rarity
The boss battle event units (Lion Fish, Gladiator Patrick, Soaring Starfish) deserve special mention because they’re Limited rarity rather than the standard rarity tiers.
Limited rarity means:
- Tied to specific events or seasonal windows
- Cannot be pulled outside the event window
- Often more powerful than their “rarity” suggests because of the time gating
- Cycle back occasionally when events rerun
The current Limited units (Lion Fish, Gladiator Patrick, Soaring Starfish) are all S-tier when available, which is unusually strong for their rarity. The dev team uses Limited rarity as a “FOMO carrot” — they want event participation, so the units have to be worth chasing.
If you’re new and these aren’t currently available, don’t sweat it. They’ll cycle back. Focus on building permanent roster units (Secret, Mythic, Exotic) for now.
How Trait equips actually work
Quick sidebar on Traits because they meaningfully affect tier list value. Every unit in SpongeBob TD can have Traits equipped — passive modifiers that boost damage, range, attack speed, or special effects.
The Trait system layers on top of unit rarity. A B-tier unit with optimal Traits can sometimes outperform an A-tier unit with bad Traits. So when I rank units here, I’m assuming average Trait investment. Hardcore optimization can shift placements.
Top Traits to chase (in order):
- Damage % increase — multiplicative with base damage
- Range extension — turns medium-range units into long-range ones
- Attack speed boost — DPS multiplier
- Critical chance — RNG-based but huge upside
- Status effect amplifier — for slow/burn units
Apply these to your S+ units first. A SpongeHenge with Damage % + Range Extension out-clears a SpongeHenge with random Traits by a wide margin.
Crafting and Fusion: Permanent Account Investment
The fusion system lets you combine duplicate units to permanently increase their stats. This is where serious account progression happens.
Fusion priority order:
- Your S+ tier carry (whichever Exotic/Secret you have) — fuse first, fuse hardest
- Your secondary S-tier unit — usually a Mythic
- Slow specialists (Dream Gary, Handsome Squidward) — slows scale value with each fuse level
- AoE specialists (SpongeHenge, Captain Magma) — AoE scaling stays valuable across content
Don’t fuse C/D-tier units except as material for your higher units. A maxed C-tier still loses to a base-level S-tier in late content.
FAQ: Real questions players keep asking
Why is SpongeHenge ranked so high if he’s just AoE?
Full AoE attacks scale exponentially against waves. While single-target units kill one enemy at a time, SpongeHenge hits every enemy in his range simultaneously. In waves with 10+ enemies, that’s 10x the effective DPS of a single-target unit with the same per-shot damage. AoE specifically dominates against the swarm waves that show up in Endless mode 25+, which is where most teams break. He’s not “just AoE” — he’s the highest effective DPS unit in swarm content.
Should I prioritize Exotic units over Secret units now?
If you can get them, yes. Mega-Hydra Karen represents a new ceiling that Secret rarity can’t match. That said, Secret rarity (SpongeHenge, Dream Gary, Cyborg Plankton) is still extremely strong and absolutely viable for most content. The realistic path: pull for whichever rarity is currently on banner, prioritize Exotic if available, settle for Secret if not.
Why is Man Ray so low for a Mythic?
Slow attacks and lower damage than other Mythics. Man Ray’s kit on paper looks comparable to other Mythic damage dealers, but his attack timing and damage-per-shot don’t keep pace with what Mythic rarity should deliver. Multiple guides agree he underperforms his rarity. The “Mythic guarantee” of strong gameplay isn’t absolute — Man Ray is the cautionary tale.
How do I unlock the 6th unit deployment slot?
It scales with your player level. Each milestone level (typically every 10-15 levels) increases your max deployment count by 1 slot, up to 6 slots. So if you’re capped at 4 or 5 deployments, grind player XP through normal gameplay to unlock more. Until you have all 6 slots, you’re handicapped against top players who can field full teams.
Are slow effects actually useful, or just gimmicky?
Genuinely useful, especially in late game. Slow effects extend the time enemies spend in your DPS windows, which becomes critical when enemy speed scales up in Endless mode. Dream Gary, Handsome Squidward, Slappy Laszlo, and Garry all carry teams specifically because of their slow effects, not their raw DPS. A team without any slow unit will struggle past Endless wave 30 regardless of how high its DPS is.
What’s the difference between Secret rarity and Exotic rarity?
Exotic is the newer, higher tier. Before Exotic was added, Secret was the absolute top of the rarity ladder. Now Exotic sits above Secret, with Mega-Hydra Karen leading the new tier. The power gap between Secret and Exotic isn’t huge for general content, but for cutting-edge endgame challenges, Exotic units have stat distributions that Secret units can’t match. Exotic units are also harder to obtain.
Should I pull the new Limited units when they’re available?
Yes, every time. Limited rarity units (Lion Fish, Gladiator Patrick, Soaring Starfish) are S-tier when available and aren’t reliably accessible outside event windows. The pull cost is justified by the long-term roster value, plus the time-gating creates real opportunity cost for skipping. If a Limited rerun cycles around, prioritize that banner over standard pulls.
How important is unit placement compared to which units I have?
Critical. Two players with identical unit rosters can have wildly different clear times based on placement alone. Corner placements amplify line-AoE units (Princess Mindy, Flying Dutchman). Chokepoint placements amplify single-target burst units. Wide-open paths favor full-AoE units (SpongeHenge). Map-specific placement guides matter as much as the tier list itself for high-level play.
Final word on this SpongeBob Tower Defense tier list for 2026
Quick recap on this SpongeBob Tower Defense tier list: in the post-Update 24 meta of May 2026, Mega-Hydra Karen, SpongeHenge, Dream Gary, and Cyborg Plankton are the four S+ picks setting the pace. The new Exotic rarity changed the meta ceiling, with several older Mythics dropping a tier as a result. Free units like Patrick Star and SpongeBob are perfectly fine for early game — don’t bench them until you have proper Epic/Legendary replacements.
The single biggest mistake I see in this game is players spreading investment across 8-10 units instead of focusing on their best 6. Resource efficiency comes from concentrating fusion materials and Traits on your S+ and S tier units. A maxed S+ team blasts past content that an underleveled diverse roster gets stuck on.
