Alien attachments

A group of aliens that were fused with Alpha and used for his intentions.

Animated series
These aliens appeared in The Alpha Syndrome fused with Alpha, but realize his plan and combat MIB but they and alpha escaped. In The Heads You Lose Syndrome they reapeared with Alpha when his plan of obtaining other alien body parts fails. Troy the symbiot is caught by Alpha after a battle with Jay, who was Troy's host at the time. The alien attachments are released when Troy's mother intervenes to retrieve her son and she regrows their missing body parts. Relieved of being free from Alpha, the aliens spare Jay and the symbiotes and attempt to make Alpha pay for what he did to them, but he has disappeared, much to their discomfort (even one states that he wanted to use Alpha's body parts for batting practice).
