Some Jalan lore  I've written down so far

Originally, Jalan would be Beast Man, Oolong, or a tiny little creature like Puar lol... but I didn't like the vision. I had started making a Sona because my friend was somewhat shy about making their own Sona. I LOVE making OCs for shows and whatnot. My long history and my reason for drawing are enough proof to make that clear. 

Jalan is a pure Saiyan. Jalan was an orphan on Planet Vegeta before Frieza blew it up. Gine and Bardock took Jalan in as a child. This means that Jalan is technically Goku's [A.K.A Kakarot] and Raditz's adoptive older brother. Jalan is thankful for Gine and Bardock's kindness and gladly took care of baby Goku. When Bardock sent Goku off in a space pod to avoid being killed by Frieza, Jalan snuck onto the pod. He promised Bardock and Gine that he would help take care of him. When the pod reached Earth, in Universe 7, Jalan was the first one to break open the pod. Jalan promised baby Goku that he would return with food when they first arrived. Jalan asked that Goku stay put while he searched for food. When Jalan returned to the pod, baby Goku was missing. Leading to Jalan to search the area. Unable to find Goku, Jalan also wandered off to an unknown area. This led to the two being separated from each other for years. Jalan eventually found a Sensei in Kung-Fu who was willing to raise and train him. Jalan is a Kung-Fu master in the Leopard Style, which focuses on nerve points and strong, fast hits. One day, Jalan was helping a nearby village with their crops when Raditz, their younger brother who also survived Planet Vegeta's destruction, came to Earth in search of 'Kakarot'. Jalan was used to Goku's Saiyan name and immediately recognized it. Jalan wasn't aware of Raditz's pure evil motive, so he blindly went with him to find Goku. When Jalan arrived at a small island where Goku was, he was excited. He rushed to greet Goku after so long but was held back by Raditz. After Raditz revealed his true intentions, Jalan immediately took Goku's side. When Raditz kidnapped Goku's son, Gohan, Jalan felt guilt and shame for blindly allowing Raditz to take him. Jalan vowed to protect his remaining family, in fear of losing them like he thought he lost Goku. Jalan has a soft spot for kids and will happily take babysitting opportunities. Jalan is GNC, and has black hair and eyes.
