Don't call it cheetah try to think of a more fantasy related name and change the pictures
Some suggestions you may (not) like:
1/ If you gave it little wings, you could call it Cockacheetah or Cheetatrice.
2/ Because of its speed, you could call it Spotted Runner|Savannah Runner (in reference to the Blue Crawler|Abyss Crawler).
3/ Or with reference to the momentum ability and it coloring, maybe Topaz Charger|Elite Topaz Charger.
Not sure if these are fantasy enough, but you don't need to credit me if you use them!
