OO Oopa

OO Oopa appeared in 1996 TV series called Gekisou Sentai Carranger. OO Oopa is Bowzock's hot springs researcher. He tried to use a beam gun that Inventor Grotch fashioned to make the Carrangers undress and catch colds so they couldn't fight – notably forcing Dappu's costume change in the process. He could summon geysers of hot water in battle, as well as throw canteens as weapons, and breathe fire. Destroyed by RV Robo.

OO Oopa is a brilliant researcher with a thing for hot springs. He sometimes managed to find a previously unknown chemical called Nekkinium which is what makes hot springs so desirable but some how went unnoticed by man for thousands of years, but he's also cool and has no trouble going after kids.

 * OO Oopa's plan for defeating the carrangers was kinda weird. He was going to use a special substance he called nekkinium. Which according to him is the reason hot springs make people want to get undressed, to make nekkie crystals and to use as ammo for a beam gun that Inventor Grotch fashioned to make the Carrangers undress and catch colds and when that failed (big surprise) he could summon geysers of hot water in battle, as well as throw canteens as weapons, and breathe fire.
