Fan Casting Eruptor (Time-Period Accurate) in Skylanders Adventures

A grumpy and kind of ditzy lava monster who came to the surface after an eruption booted him from his volcanic homelands, and now uses his magmatic powers to fight off evil. Eruptor's bumbling nature and short temper mean he's not always the most adept fighter, but hey, he's getting there—especially due to being the Fire Element Faction's leader. Later on, he along with the other faction leaders head to Earth to help Jake find the Hope Bringer's new incarnation using disguising magic, with him taking the form of a mid-late 20s aged man and adopting the alias Ernest. Vaguely adult-aged. Only suggest 2000s/early 2010s VAs.
