Evolved villains, with every villain getting a variant of their evolved form/color scheme from TT ( including Kaos )
Sheep Mage variant for Chompy Mage ( never gonna happen though...largely because they'd have to alter the sculpt & attacks/animations )
Legendary Crash Bandicoot, Ember, Starcast & Hood Sickle ( we know there will most likely be a few Legendary & Nitro variants, just not who or how many )
holiday variants of Chopscotch & Pain-Yatta ( just for the love of Eon, no Eggcited Thrillipede monstrocities

an Ember variant with blue flames ( not sure what to name her though.... )
