Them's Fightin Herds is a really fun fighter. There are always people online, and the animation alone is pretty good! To further support this My Little Pony-like fighter, Mane 6 and Modus is still throwing out DLC characters, and the second one is Stronghoof.
Stronghoof comes with ice attacks, which sometimes turn into a sword, or a hammer, and of course, combos out the North Pole. (He's not from the North Pole). He also comes with a little sprite, to help him in battle, and extend his already lengthy move set. Check him out in the trailer below. if you have the season 1 pass, he is already on your game, pending an update of course. If you don't, you can purchase him as a standalone character for $4.99 USD. He also comes with his own stage.
