Billy shouldn't charged is because he is the first one being made officially(sprited/coded) for MUGEN, and his current set of moves look like a rush-down character. Think about TMNT Donatello, He isn't charged.. He is also a genious.
But your List makes sense. Totally agreed with Duck King /Black Ranger.
This Billy should be something more, is basically what Im saying. I lay this propoganda here for your consideration.

"Despite Billys genious, he felt underpowered and letdown by some of his fellow rangers; not satisfied with his fighting abilities, he started to gather facts and Intel about various martial arts. He started venturing into the streets at night to get a feel for his training methods and defeated various robbers trying to rob Mcdonalds
from stealing Sprite. He also regularly scouts the streets at night to stop drug trafficking.
He has been currently training with various styles, including Taichi, Quanchi, Hapkido, and Lin Kuel.
He has new motives.."
