Joins the Megaforce Rangers, betrays the Megaforce rangers and then turns into a monster?

Sounds delicious.

I doubt Basco will appear in Super Megaforce, there just isn't enough space to properly justify him (he mostly appeared in episodes where the Zangyack did pretty much nothing, except for Damarasu's two-parter, but every scene with him in that episode could be cut out easily) and also I'd cry if such a cool, evil and wonderfully eccentric character was adapted into someone as lame as Tommy. If they made their own original villain plot, then yeah, I guess Tommy could be it, but I doubt they'd do anything to tarnish those nostalgia glasses of the fans, I'm sure pretty much all of Tommy's appearances will be all the characters sitting around boosting his Canon Sue status.

I'm pretty sure Basco is just gonna be another form for Vrax.

Eh, I wouldn't hate that, to be honest.
