Flanders Edison is a genius in his normal form but when he grows into his Rumble persona, his intellect drops drastically. It is unknown the extent of his growth powers but he has been pictured as tall as 10-story buildings. He generally wears his magically derived costume under his clothes that grows with him and is immune to ripping and tearing (except by magical attacks).
At his normal size, Edison is quite skilled at translating ancient languages.
