Exclamation Question

Exclamation Question (!?) was a Japanese creator famous for their conversions of characters from various bootleg games. His conversions were mostly source accurate with a few exceptions, but were nonetheless well received, especially his Kart Fighter conversions, as he was the only known creator to have fully converted the game's entire cast.

He chose to retire on September 14th, 2019, citing his reasons as having his work and personal life becoming drastically busier, giving him hardly any time for creating characters.
