Dr. Muto

Gameplay involves collecting these items. Isotopes can be found anywhere, while Terra pieces are collected by completing challenges. The Genitor 9000 pieces are earned by defeating a planet's boss. Each planet also holds seven scrap parts, which Muto can collect to find new gadgets such as rocket boots or an invisibility suit.

Dr. Muto can jump and zap enemies, but he can also transform into different creatures using his Splizz Gun. These transformations allow him to access new areas and use special abilities, like the mouse being able to squeeze through tight spaces or the pterodactyl being able to fly.
