'sup guys.
I had a dream that Team Rocket were added to Smash as playable characters; however, you actually played as Jessie & James themselves instead of Meowth and their Pokemon, and they had "familiar" fighting moves that I don't actually remember them using (my mind probably just based their moves off of moments in the anime when they're acting goofy or panicking or something...).
They used their Let's Go! designs for some reason (probably with longer legs), though to be fair they were shown with dramatic, comic book-like backgrounds instead of normal Smash stages and no other characters were shown, so you couldn't compare them with the rest of the game (high-quality gameplay trailer, Team Rocket really needs to make some cash).
