Crystal is your average teen kid always wears jeans blue or black usually, T-shirts and Nikes. Medium hair with slight highlights.
Crystal's personality is normal fun to hang with teen and gets intensely focused at times ex. battle and is really protective of what he cares about.
Crystal can use about anything to his advantage but carries a knife or gun at hand his fast as well and well built he's not completely buff like bodybuilders but you get the point
Crystals background is about average he was in kung fu until his parents couldnt pay for it anymore and they had to move. His dad could barely keep enough money for them and then this happened... so yea
