I do love these villains and characters a lot, would’ve liked to see them do some larger arcs. Particularly Magicka de Spell. But yeah, does feel like they’ve mined most of the gold out of this nugg.
Would love to see the team take on any of the spinoffs they’ve set up, but if this is due to the show not having high enough ratings on Disney XD, there’s no fixing that. Anything they air on that network is going to fail to bring in the ratings they’re after.
