Well, I just watched the new trailer and the gameplay for Pokken, and jeez, does that look awesome. I can't wait until it gets moved to Wii U, probably around November-December 2015. Anyways, I think that these would be my top 10 wanted fighters, and as a warning, there will be a lot of Steel-type in this list, but I will try to refrain from only Steel-Types
1: Genesect.
Since my avatar is Genesect, and he is my favorite Pokemon, this should be expected from me. I think his style would revolve around fast attacks, and his techno blast being different with each drive: Fire: stage control/damage; Douse: Stage Control; Shock: Anti-Air or Stun; Freeze: Air Launcher, similar to the freezie in SSB.
2: Mewtwo
Wanted by many, he/she/it is high on the list of many, due to its deep backstory and incredulous abilities. Gameplay would most likely revolve around a balanced attack and probably teleporting to confuse opponents to keep pressure off or put pressure on. (No pun intended)
3: Aegislash
Since the fighters aren't limited by typing or if they're bipedal, this spirit sword is high on my list. He might be somewhat slow, but with Stance Change being utilized in battle, you'll be able to slice up your foes, or keep them off of you, just be sure to plan your attacks wisely.
4: Bisharp
Bisharp, probably one of the Pokemon that's just a punching bag for Fighting-types can get his revenge. His style would most likely be little range, but decently fast, running around the stage and some acrobatic tricks in the mix to put a hurt on his opponents, no matter what he hits them with. Dodge and counter, slice and dice, block and stab.
5: Lopunny
Although Lopunny can't take hits very well, they can sure deal them out excellent. Lopunny would be fast, agile, and would jump high, making your opponents think twice about using air launchers.
6: Sceptile
Sceptiles are fast, agile hunters of the forest. Known for their signature move, Leaf Blade and amazing sweeping, they strike through opponents with ease. Sceptile would be undoubtedly fast and agile, but would have some techniques to keep his defense up.
7: Greninja
Fast, confusing, and deadly, this Ninja Pokemon will have your opponents constantly thinking with moves both to throw opponents back and to you, and make their shields beg for mercy.
8: Flygon
Fast and known as the Mystic Pokemon, Flygons are known for their attack prowess and ground powers that could rival Groudon. In Pokken, Flygon would be fast and would rush you down in a heartbeat, instantly tearing at your life and shield, but once left open, will be taken down if not careful.
9: Regis
Although not technically one Pokemon, all the legendary golems would be interesting choices, trading out speed for stage control and defense, while Regigigas may be slow at first, but once he activates his power, will tear at you quickly.
10: Hawlucha
The Wrestling Pokemon, Hawlucha will take both to the skies and the ground to grab opponents and toss them around like nothing. Hawlucha dives, presses, and bombs you as you whittles away your health.
So, what are your ideas?
