As always, the name of the game is to get people who follow these celebrities in to watching the show.

Peter and Paul make sense - current and former Power Rangers actors.
Andre - Saban has had him on speed dial for years, even though the larger he becomes, the more he ignores Power Rangers content
Meghan - no idea. Probably someone at HyperRPG giving her a "big break"
Vee - voice actress, though no ties to the show

EDIT: So Meghan is actually a big name YouTuber who has been on such shows like The Amazing Race (twice), and DisneyXD.

Overall, a star-studded cast with a rich background. Should be interesting.
