Wire Sponge was stationed at a weather control center, and told to wreck the weather systems.  Wire Sponge acts like a spoiled child, who wants only to have fun and destroy everything around him.

I don't want him to have an actual child voice, maybe somewhere in-between surfer dude, and whiny douche.

*Wire Sponge Re-appears in Megaman Xtreme 2, and we currently plan to do that following X3, so you'll be called on again to reprise the role there!*
