Quark was created by Arize to be part of the slave race in Mojoworld. Hearing of the exploits of Longshot he was inspired to fight for freedom. Pretending to still be working for Mojo he got himself on a team sent to Earth to hunt Longshot. After some misunderstanding he was able to convince Longshot he wanted to help him and eventually accompanied him back to Mojoworld.
Once there both were captured and after some time a brainwashed Quark was sent against the X-Men.
Somehow regaining his free will Quark later helped Longshot in his rebellion in Mojoworld.
