Nope, Jetray and Fasttrack never did. Setting aside the opinion of which aliens are and aren't cool, Ghostfreak and Big Chill have different abilities from ChamAlien.

Spitter makes sense not to have been seen, since he hasn't been "unlocked" yet. Though at the same time, I do kind-of wish we saw some different aliens used by Ben 10,000 in Omniverse (not just new combinations of already-existing aliens).
