Onion

"" is a minor character in Steven Universe and a resident of Beach City. He first appeared in "Laser Light Cannon" as a cameo character. He is either Sour Cream's step-brother or half-brother as revealed in "Joy Ride."

Appearance
Onion is a fair-skinned boy with a small tuft of blonde hair and a chubby face. He wears a white sweater, a blue shirt tied around his neck, and red footie pants. His most recognizable trait is his onion-like head (although the top is thinner than the bottom, not resembling a normal onion). He also does not have any visible ears.

Personality
Onion is a very quiet kid who chooses not to speak to anyone except for his dad. When he speaks to his dad, it is in an unknown language, which sounds like muffled gibberish. Onion is eager to help people. He will blindly follow orders even if they don't seem very well thought out, such as in the episode "Bubble Buddies," when he shot a harpoon at Steven's bubble. He cannot stand being lied to, especially by close friends, as shown in "Steven's Lion." He has been seen to be bad as in "So Many Birthdays," he was seen stealing tickets from an arcade machine, which explains how he had enough to win a moped in "Arcade Mania". This is further emphasized in "Onion Trade" with Onion's delinquent behaviors such as destroying the moped for no apparent reason. Onion's delinquent behavior can be attributed to his severe loneliness, due to his father constantly being at sea. He does not seem to understand or simply not care when and if he is hurting people, has no qualms with stealing what he wants, and does things obliviously in the name of fun. This could be attributed to his young age and lack of moral understanding. He continues his bad acts in "Watermelon Steven", when he steals Steven's Baby Melon despite Steven stating he wasn't for sale. In "Political Power", Onion seems to be on the verge of attacking Mayor Dewey as he held his baseball bat menacingly.

Steven
Steven is Onion's friend whom he is eager to help and has known him in the past. They may get along but it is a one-sided relationship as Onion isn't known to talk to anyone.

Yellowtail
Onion doesn't see his father often, and this causes Onion to spend a lot of time wandering around, unsupervised.

Connie
Onion and Connie have only met once in Bubble Buddies, but Onion has been shown to be able to understand Connie easier than Steven.

Sour Cream
Onion and Sour Cream have never been seen interacting, although they are shown together in the evacuation of Beach City in "The Return" and the opening theme. In "Joy Ride" it is confirmed that Sour Cream and Onion are either half-brothers or step-brothers.
