Super Mario RPG: How To Defeat Megasmilax

Welcome to our boss guides for Super Mario RPG on Nintendo Switch and SNES.

A Piranha Plant boss was bound to happen at some point in Super Mario RPG, and here it is! You'll encounter this beast party-way through your journey in Bean Valley. Megasmilax isn't too tough an obstacle, particularly if you have some of Peach's better healing spells. But if you need a push over the edge or find yourself in a bit of trouble, we're here.

Here's our guide on how to beat Megasmilax.

How to beat Megasmilax

Recommended party: Mario, Mallow, Peach or Bowser

The first phase of this boss is incredibly easy: just attack the Piranha Plant with physical moves a couple of times. When the head pops, the Shy Away will return and water the plant, causing two heads to grow.

These two heads are separate targets, and they’re both weak to ice. Attack them with more physical attacks plus Mallow’s Snowy spell. The two heads will eventually pop, and Shy Away will return once more and water the plant to grow three heads at once!

Use the same technique against the trio of Piranha Plants and the Shy Away will come back one final time and create Megasmilax. Fortunately, its weaknesses and resistances don’t change, so keep attacking with physical moves plus Mallow’s ice spell while making sure to heal and revive your party members along the way.

You can even end the fight with a Triple Move if you want to end things in an explosive way. And that's that.
