Experiment No. Z-57 is one of the last boss battles of the game. The reanimated course of the first boss Corpius, this is by far one of the most frustrating battles I can remember in Nintendo history.

Experiment No. Z-57 surprises Samus shortly before she completes all the secrets of the world.

When the monster was originally living, it was definitely one of the scariest beasts in that world. And when they turned it into a zombie, they made a super version that acts more like a spider than a scorpion.

The battle has multiple phases of attacks. You’re not safe during any of it. Those claws will rip you to shreds.

And that big giant laser will obliterate you pretty easy, if you’re running low on health.

And the endurance of this beast is absolutely insane. He just will not die…

The first phase took me many different tries and eventually I mastered it. Then it took me probably three times as many tries to finally beat the second phase.

I have never felt so accomplished to defeat a video game boss before in recent memory. After he fell into the lava, I was definitely saying “good riddance.”
