To be fair to that episode of Omniverse, OV tried its best to make sure Vilgax was never a season-long villain. making vilgax the inevitable final threat in a series was a trap both AF and UA fell into and it got boring. Even when Cthulu was on his side. Keeping him out of the spotlight kept OV fresh and made his appearance in malgax attacks actually kind of suprising (unless you read the title of the episode beforehand)

That being said its fair game for the reboot to use Vilgax as it pleases, since it is a reboot.
