Can't remember if I stated my ideas about them here already, but I believe they'll be upgrades of their signatures. Rillaboom will have a binding move that lowers speed every turn, kinda like Octolock, Cinderace will have guaranteed burn, and Inteleon ignores all effects, meaning screens, moves, abilities, weather, and stat changes.
that ball reminds me of Steamroller. Its football related? Breaking through Protects and Max Guards?
