So this is an old animation from 2 years ago, I'm uploading this now because I want to continue the series. Since this is from 2 years ago the animation isn't the best, but episode 2 will be much better.
Plot:
David Martinez, 10 years old, likes to fight. In his school, it gets you a title. The best fighter in the school: Christina Chavez. In short David challenges Christina and gets rekt. After some boasting/sulking, he finds a news ad for an experimental procedure to make someone stronger (pretty shady stuff). Without thinking David goes to the place, and things don't go so well...
Characters:
David Martinez - Fireboy
Matthew Vazquez - David's Best Friend
Christina Chavez - David's Rival
