|First Appearance||Men in Black: The Series
Agent U (also called Upton, or just U) is an MiB agent, and a bit of a kiss-up.
- There is a running gag where U's codename and the word "you" get mixed up.
- In one of the episodes of the MIB animated series titled the Buzzard Syndrome, Agent U caught a small alien J and K were unable to, this in Zed mind made him a rival to Agent J in some ways.
- Agent U thinks that J is not a good agent because he says U's real name and gets his suit riped
U takes it as a carless agent to Zed.
