Boris the Animal

Boris the Animal (performed by Jemaine Clement) is the main antagonist of Jeffrey, Jaden, & Friends' Storm Adventures of Men in Black 3. He is the last of the Boglodites aliens that had a score to settle with Agent K. He broke out of prison and went back in time to kill Agent K in 1969. But Agent J, Jaden, Jeffrey and their team followed him, and was able to kill both his 2012 and 1969 selves just in time before they could rewrite history.
