Kay-o, appariently the Believix comes with a few cool features, one of which being the "Speedix" wings! Acording to the Blog "Una di Noi", the Speedix wings are part of a set of three special wings. As of now we are unsure about what the other wings will be called.
The author of the blog says, "Do you think Rainbow has gone overboard with this naming scheme? I admit it’s taken me some time to get comfortable with “Believix.” (Other fans had some interesting names for it before we knew the real one; “Glamorix” and “Elementix” were my favorites.) Don’t get me wrong—I like the name a lot now. But “Speedix?” It might be the end of the season before I can stand that one, and I can only imagine what the other two are."
Actually, Glamourix and Elementix were two names I had came up with for the new transformation. I also came up with Glitterix (my fave), Sorcerix, Pinx, Twinx, and Alurix.
Here's a vid of this "Speedix":
