Rumble

Rumble is a young inventor with a temper. Using nothing more than his own two hands and a heap of scrap, the feisty yordle constructed a colossal mech suit outfitted with an arsenal of electrified harpoons and incendiary rockets. Though others may scoff and sneer at his junkyard creations, Rumble doesn't mind—after all, he's the one with the flamespitter.
