Qwark is going to have different roles in the movie and the game. In the movie, he'll sabotage a mission to gain glory, which ends up disasterously failing. In the game, he could be the villian: when he was talking to ratchet about the snagglebeast, he sounded like he purposely put him in there.
"So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal."
