Lavasioth is completely changed, almost all of its attacks are different now.

Blangonga has one new attack, a few adjustments to old moves like the tracking in the rocket punch, and new animations for turning around. Which isn't really much but actually makes it one of the old monsters that was changed the most for Generations.
