Ken is one of the toys from Sunnyside Daycare. He is one of Lotso's henchmen, but is considered a weakling and constantly teased by the other toys.
Ken loves fashion, dance and bright colors just as much as his girlfriend Barbie. He resents being called a "girl's toy," as a human male might have with their masculinity being put into question. He also rather dislikes attention being drawn to the fact that he's essentially an accessory to Barbie.
