What Is Marine Hero (Garp) in Universal Tower Defense X?
Marine Hero, commonly referred to as Garp by the community, is a Secret-tier unit in Universal Tower Defense X based on the legendary Marine Hero Monkey D. Garp from One Piece. He was introduced in the Universal Festival 1.5 update and has remained one of the top-tier units for boss damage and warlord team compositions.
He is a Ground-type unit with a spawn cost of 2,000 Yen, making him a mid-to-late game investment. What sets Garp apart from other Secret units is his combination of damage-boosting passives and built-in critical rate enhancement on every placement. He also carries stun immunity, which means he stays active and dealing damage even when enemies try to shut him down.
Players who run Pirate King team compositions will find that Garp fills a crucial role. His passives scale with warlord synergy, and his raw damage output makes him one of the best picks for tackling high-level content like Admiral Defense and endgame boss fights.
How to Get Garp in Universal Tower Defense X – Complete Trial Steps
Getting Garp requires completing the Marine Hero Trial, which is a multi-step questline that tests your progression, grinding ability, and a bit of luck. To start the trial, press the Quests button on the left side of your screen and navigate to the Marine Hero section. The trial consists of five sequential steps, and you must complete them in order. Here is the full breakdown.
Step 1: Talk to Marine Hero in the Lobby
Your first task is straightforward. Head to the lobby area and locate the Marine Hero NPC. Interact with them to officially begin the Marine Hero Trial. This NPC will serve as your quest hub throughout the entire process, so remember where they are located because you will be coming back after each step to check your progress and claim rewards.
Step 2: Evolve the Required Units
The second step requires you to evolve specific units that the trial demands. The Marine Hero Trial expects you to show progression by evolving certain characters, proving you have the resources and game knowledge to handle a Secret-tier unit. Make sure you have enough Gold and Fragments saved up before starting this step. The evolution requirements can catch players off guard if they have not been farming materials consistently.
You will need Universal Fragments and standard evolution materials. Check the quest log for the exact units required, as these can change with game updates. Having a stockpile of around 25,000 Gold set aside for evolution costs is a smart move before beginning.
Step 3: Complete Admiral Defense 25 Times
This is where the grind begins. The third step requires you to complete the Admiral Defense game mode a total of 25 times. Admiral Defense is a wave-based challenge mode that tests your team building and placement strategy. Each run takes several minutes, so expect to spend a significant amount of time on this step alone.
The key to clearing Admiral Defense efficiently is building a team with strong area-of-effect damage and reliable single-target damage for boss waves. Ground units with stun capabilities pair well with ranged units that can handle flying enemies. Focus on upgrading your core damage dealers early in each run rather than spreading your Yen across too many units.
Players on Reddit report that each Admiral Defense run takes roughly 5 to 8 minutes with a solid team, putting the total time investment for this step at around 2 to 3 hours of focused gameplay.
Step 4: Obtain the Pirate King’s Hat
This step is the biggest roadblock for most players. The Pirate King’s Hat has an 8% drop chance from a specific boss encounter, which means you could get lucky on your first try or spend hours grinding for it. Community data shows that most players get the drop within 10 to 15 attempts, but the variance can be frustrating.
The good news is that there is a pity system in place. If you have not received the Pirate King’s Hat after approximately 20 runs, the pity system guarantees the drop. This means even with the worst possible luck, you have a hard cap on how many attempts you need. Plan for somewhere between 5 and 20 runs, and budget your time accordingly.
One tip that experienced players share is to run the encounter with a team optimized for clear speed rather than trying to maximize rewards per run. Faster clears mean more attempts per hour, which directly improves your chances of getting the hat sooner.
Step 5: Complete the Marine Hero Trial
Once you have finished all four previous steps, return to the Marine Hero NPC in the lobby to complete the trial and unlock Garp. The NPC will verify that you have met all requirements, including the Admiral Defense completions, unit evolutions, and the Pirate King’s Hat. After the final dialogue, Marine Hero Garp will be added to your unit roster.
Congratulations, you now have one of the strongest Secret units in Universal Tower Defense X. But the work does not stop there. To unlock Garp’s full potential, you need to understand his evolution and passive abilities.
Evolution Requirements and Materials
Evolving Marine Hero into his upgraded form, Marine Hero Grand Fist, requires a specific set of materials and a substantial Gold investment. Here is what you need to collect.
The evolution process calls for 6 distinct materials, including Universal Fragments, standard Fragments, and items that drop from specific game modes. The total Gold cost sits at 25,000, which is manageable if you have been saving up but can be a hurdle for newer players.
Universal Fragments can be farmed from the Virtual Merchant and special event modes. Standard Fragments come from completing story stages and daily challenges. The remaining materials drop from Admiral Defense and other high-level content, which means your 25 Admiral Defense completions from the trial may already have given you a head start on some of these items.
Plan your farming routes around the Virtual Merchant for Universal Fragments and Admiral Defense for the mode-specific drops. Running daily challenges consistently is the most reliable way to build up your standard Fragment stockpile without burning out on a single activity.
All Passive Abilities of Marine Hero (Garp)
Garp comes with three passive abilities that define his playstyle and make him a powerhouse in the right team composition. Understanding how each passive works is essential for getting the most value out of every placement.
Iron Fist
Iron Fist is Garp’s core damage passive. It provides a direct damage boost to his attacks, scaling with his level and placement upgrades. This passive is what makes Garp so effective against high-health targets like bosses and elite enemies. When combined with critical hits, the damage output becomes substantial enough to carry entire waves on his own.
Hero of the Marines
Hero of the Marines is a team-oriented passive that boosts the performance of Marine-aligned units on the field. If you are running a Marine or Pirate King themed team, this passive adds meaningful damage scaling to your entire lineup. The boost applies to units placed after Garp, so timing your placements matters for maximizing the benefit.
Unbreakable Will
Unbreakable Will grants Garp stun immunity, ensuring he continues attacking even when enemies use stun abilities. In higher-level content where stun mechanics are common, this passive alone can be the difference between a clean clear and a failed run. It also pairs well with his high damage output, since he never loses uptime to crowd control effects.
Together, these three passives create a unit that hits hard, supports his team, and never stops attacking. The critical rate boost on placement further amplifies his damage ceiling, making Garp one of the most consistent Secret units in the current meta.
Best Traits for Marine Hero Garp
Traits can make or break a unit’s performance, and for Garp, the community consensus is clear. The Ruler trait is the best choice for Marine Hero Garp, and it is not particularly close.
Ruler enhances Garp’s damage scaling and synergizes with his warlord-focused kit. Since his passives already provide strong damage boosts and team support, Ruler amplifies those strengths rather than adding an unnecessary utility layer. Players on the Universal Tower Defense subreddit have tested alternative traits, and Ruler consistently outperforms in both raw damage and overall clear speed.
If Ruler is not available, look for traits that boost critical rate or direct damage. Avoid utility-focused traits since Garp already has stun immunity from Unbreakable Will. His kit is designed around dealing as much damage as possible, and your trait selection should reflect that priority.
Admiral Defense Strategy Tips
Since Admiral Defense is a major part of the Garp unlock process, here are strategies to make your 25 completions as efficient as possible. Most guides mention that you need to complete it 25 times but never explain how to actually beat it consistently.
First, build your team around two core concepts: area-of-effect damage for wave clearing and single-target burst for boss waves. A balanced team of 4 to 6 units with complementary roles will handle most Admiral Defense encounters without issues. Prioritize units with upgrade potential since late-game waves demand significantly more damage output than early ones.
Second, upgrade your main damage dealer to max level before investing in support units. Spreading your Yen thin across multiple units early in a run often leads to falling behind on damage during boss waves. One fully upgraded carry unit performs better than four partially upgraded ones.
Third, learn the wave patterns. Admiral Defense has predictable wave compositions, and knowing when boss waves arrive lets you save resources for critical moments. Practice runs where you experiment with different placements and timing will pay off in faster clear times over the full 25-run grind.
Finally, if you are struggling with specific wave compositions, check the Universal Tower Defense subreddit for team recommendations. The community regularly shares Admiral Defense comps that work well in the current patch, and player-tested strategies are often more reliable than theory-crafted builds.
Pity System and Drop Rate Explanation
The Pirate King’s Hat drop mechanics deserve their own section because this is where most players get stuck. Understanding exactly how the pity system works can save you frustration and help you plan your grinding schedule.
The base drop rate for the Pirate King’s Hat is 8% per attempt. On average, this means you should expect to get the hat within 12 to 13 attempts. However, probability does not guarantee results, and some players report going 15 or more runs without a drop. This variance is completely normal with an 8% chance.
The pity system exists as a safety net. After approximately 20 attempts without receiving the Pirate King’s Hat, the game guarantees the drop on your next run. This means your worst-case scenario is around 20 to 21 total attempts, which translates to roughly 2 to 3 hours of focused farming with an efficient team.
To put the numbers in perspective, you have a 81% chance of getting the hat within 20 attempts based purely on the 8% drop rate. The pity system kicks in only for the unlucky 19% who have not received it by then. Most players fall somewhere in the middle, getting the hat between runs 8 and 15.
