When the trailers for Invincible Season 2 were released, fans were stoked to see J.K. Simmons' Omni-Man back in play. Fans were wondering if he'd be kept for the last half of the season after he betrayed Earth and fled in Season 1. It would make sense to build some anticipation rather than rush him in again. The snapshot made it seem like he was still a cold killer, so the intrigue was at an all-time high.
