It just struck me that the new character might have a toned-down version of Algol's moveset. I know that sounds stupid, but follow me here:
Extendable fore-arm mounted blades: From the art we see that one's extended and one's retracted. I wouldn't be surprised if they only spring out when Don Pierre swipes his arms, basically giving him Algol's SE and SC attacks with shorter range.
Coins: Weaker bubbles, faster travel and shorter range.
Chair: Throne. Character art usually doesn't include elements that the character doesn't have in combat anyway, and we already have a character who fights with his chair. As for the teleporting involved, Don Pierre has the "magical circus ringmaster" stereotype that's common in manga and anime, and teleporting is often part of that package.
The two things that don't immediately snap-to are the question of floating/walking and whether he would retain Algol's non-arm-based sword-creation attacks (like when the spikes shoot out of his back.) I'd imagine that the animations would be modified so that he only gets the arm-swords, perhaps replacing the ribs and spikes with confetti or magical energy or something.
[edit: I should have looked at the pic again, I didn't notice a bunch of details (including the four suits on his crest.) I still think he's got the big top elements going, what with the onesie, the top-hat, and the ring-master's jacket. Still, he's also got some magical gambler elements in there. He may very well throw cards instead of (or in addition to) coins. Also, did anyone notice that his chair-back is a giant rat (wearing a crown) with his mustache? Its face is obscured by the skull emblem, but it's clearly a rat or neutrino or pikachu.]
