When fans learned J.K. Simmons would be voicing Omni-Man (aka Nolan Grayson) in the Mortal Kombat 1 reboot, they were very ecstatic. This addition was a massive way of hooking Invincible loyalists who lapped up the idea of Omni-Man being released as a DLC player ahead of The Boys' Homelander. It's all about bragging rights, and seeing as Invincible has been one of pop culture's biggest hits in the last couple of years, it really stood out as a crossover made in heaven for Image Comics readers.
