Helio is a character that originally appeared as an unnamed boss in Wario Land 3. In the boss battle, Wario must do a ground pound on his head to release an accordion-shaped device from his mouth. Then, Wario must do a ground pound on that in order to inflate Helio, and the entire pattern must be repeated twice more in order for the boss to be defeated.
Helio, like many other Wario Land 3 characters, later appeared in Dr. Mario 64. He patrols the sky, watching for ongoers. In Dr. Mario's story (when people choose him to play), he is angered by Dr. Mario and Wario while they chase Mad Scienstein to get the Megavitamins. Because of this, he pokes Wario and Dr. Mario, who's just behind Wario, has to play him in a match.
Traits
Helio looks like a balloon with arrowheads on his arms. Apparently, there is a toxin that turns Wario into Balloon Wario on the tips of the arrowheads. Helio is easily frustrated, as portrayed in the game.
