The Octovader is an enemy that appears in Super Mario RPG: Legend of the Seven Stars. Octovaders are octopus-like enemies that can be first encountered in Land's End. Octovaders are stronger versions of Octolots.
In battle, Octovaders are capable of using a lot of special moves. It can use lightning-based moves such as Lightning Orb but it's most powerful is Drain Beam that can attack everyone in Mario's party. They can also use Sleep Sauce in attempt to put the party to sleep.
Octovaders are weak against fire meaning any of Mario's fire techniques such as Super Flame are very effective against them.
