Yakuza

Yakuza is a huge spider-like boss from Metroid Fusion that is found in the Reactor Silo. It holds the Space Jump ability. It is considered one of the hardest bosses in the game.

Yakuza, suprisingly, is not that hard (if you get the hang of it). The trick is to enter Morph Ball mode and stay on a line near the far right corner. Yakuza will not exhale fireballs here. Yakuza's fireballs will go in three places: the far left corner, far right corner, and right below it. If Yakuza is right above you, yes, it's fireballs will damage you if you are on the "safe spot". When Yakuza's mouth opens, right before he exhales the fireballs, Samus must shoot it rapdily with missiles. Once enough damage has been caused to it, Yakuza will lose its legs and start hopping around throwing balls of its web at you. Like before, Samus must shoot missiles at its mouth. Once this stage is done, Yakuza will turn into a X|Core-X, and normal procedure should be followed from there. Once defeated, Samus must use the Space Jump to get to the top of the room and out towards the left.
