Cataclysm: Incredibles 3 Villain

This is some concept work for a university course. We were assigned to create a villain for the next Incredibles movie.

His backstory:

Henry constantly stores up energy and eventually explodes without warning. Because of this, he grows up resenting superheroes and powers and begins studying energy and explosions. One day he has a really bad explosion leaving him partially paralyzed. Buddy, knowing he is a brilliant scientist and a superhero hater goes to save him, not knowing that Henry has powers. They work together studying energy and technology. Henry explodes in secret, as he has slightly more control now. Eventually, a disagreement in ideas creates a rift between Buddy and Henry, and Henry undergoes surgery to augment his body so he has control over his power. Syndrome finds this out, feels betrayed, and lays a trap. He underestimates Cataclysm's power and Cataclysm explodes half of the island and escapes to form his own evil organization.
