Meron is an alien scientist who works in the medical bay of Frigid's Battleship. He isn't a fighter, and has no control of his own ki.
He is a minor character in Dragon Ball: Uprising. His name is a pun on the fruit Melon.
Meron is a seemingly ancient looking reptilian alien with faded green scales that seemingly cover every part of his body. According to Kaido, Meron always looks like he's a few seconds away from molting like any other reptile. He also has cloudy yellow eyes that are apaprently still good enough for medical work.
As he is not a fighter, he wears simple black and brown battle armor that sports a nice white cape.
