Considering they have a strikingly similar appearance, same theme and same voice, it could be speculated on that they are the same.

At least for Cosmic Mario, since they both also act similarly.

And I'll probably add Junior to the profile at some point, but at the moment, he's not added. Partly because I'm still debating with myself where exactly to place him at.
