Level 20 Boss Guide: How to Defeat the Destroyer Mech Giant 👾
By the Trap Devil Fury team | Published: 23 October 2026 | Reading time: 4 min
Level 20 is the peak of the challenge in Chapter 1 of Trap Devil Fury. You are locked in an arena with the Destroyer Mech Giant, which has 3 HP. The victory gate only opens after you defeat it.
Understanding the boss's attacks
- Constant movement: the giant floats left and right across the arena and launches homing saws aimed at your position every few seconds.
- Rage mechanic: every hit makes it angrier. It moves faster as its HP drops, and it attacks more often, so the later hits are the hardest.
Plan for the three hits
- First hit (right side): at the start of the fight, the first glowing blue energy charge (âš¡) sits on the high right platform. Use the bouncy pad below or jump and dash to touch it. A bolt will hit the giant and remove one HP.
- Second hit (left side): after the first hit, the charge moves to the high left platform. The giant is faster now and will fire a saw at you. Drop down first, then use the left bouncy pad to jump over the saw and touch the second charge.
- Third and final hit (middle): the last charge appears in the exact middle of the arena. This is the most dangerous moment. One carefully timed jump with a dash should finish it.
What happens after the boss falls?
When the third hit lands, the mech explodes with a burst of visual effects and colorful confetti, and the golden victory door appears in the middle of the platform. Walk through it to finish Chapter 1 and prove you are a true platformer champion.
