Captain Ginyu leads the Ginyu Force, an elite mercenary squad feared across the galaxy. His name is basically a pun on the Japanese word for milk, which fans find either amusing or groan-worthy depending on who you ask.
Despite his ruthless reputation, Ginyu genuinely cares about his team—he flies into a rage when he finds out three of his men have been killed, though he's not above harsh criticism if they mess up. He scolded Jeice hard for losing to Goku and retreating instead of standing his ground. When it comes to Frieza, though, Ginyu is all loyalty, taking orders without question.
Frieza once remarked that he didn't think anyone in the entire universe could match Ginyu in a fight, which says something about how formidable he actually is. Not many people have witnessed Ginyu at full power—Salza is one of the rare few, having faced him directly in a showdown to become leader of Cooler's Armored Squadron.
