Chaoticore:

Age: 32
Height: 8'2" / 2.5m

Chad Aristan started off as a professional wrestler who was determined to make a name for himself, but he was banned for being too brutal in and out of the ring. He dropped off the radar for a few years before returning as Chaoticore, a portmanteau of chaotic and manticore. He has been altered physically as he now is over 8' tall and has white irises and a spiked tail that can launch its spikes. He was yet again determined to make a name for himself, but this time his goal was to defeat superheroes.

Known powers:
Permanent, innate growth (now 8'2" / 2.5m)
Spiked tail with regrowing tail spike projectiles
Enhanced strength
Leaping (30')
Terrifying Roar (sense-based power: auditory)

This was done by the excellent tsbellatre.
