Hearts Swift or Hearts the Cheetah is a cheetah who loves money and and was born into a rich family. She is the sex symbol of the My Sonic Heroes Manga. She is a spoiled brat. She is 19, is 3' 5 and her weight is unknown.


(coming soon)


She is a strong-minded and independent woman. She is also ruthless, cunning and can seduce people with her sex appeal to get what she wants. She is also quite spoiled and can be a brat. She will do anything to get money and get rich. She also enjoys a good fight, especially verbal fights. She loves to makes fun of people behind their backs and she isn't very friendly toward people unless they give her something she wants. She also curses alot. Despite her unfriendly nature, she has shown romantic feelings toward Kyle and maybe Fang the Sniper (but she only dated him to get money).


Hearts is a master of sleath and spying, which took her years to perfect. She can also run very fast but in only short, long distance bursts, then has to slow down. She knows how to use a gun but has never been seen firing it. She also knows how to play poker. Here are all of her known moves:

  • Spin Attack
  • Spin Jump
  • Slide
  • Homing Attack
  • Spin Kick
  • Tornado Kick
  • Hearts' Secret Attack (only used in Sonic Boomhog: FIGHT!)
  • Mega Punch
  • Mega Kick

She has no known super form and her ability type is speed.


She is not very friendly, which leaves her with very little friends. She is also poor and can barely get herself by and relies on Radic for money. Despite being fast, she can only run in short, long distance bursts then has to slow down.
