Since my self-character has no real bio or anything I guess I'll give 'em one. I wanted to be a little bit cliche though.
Age: 14 (I literally forgot my age IRL, but I'm sure I'm 13)
Father: Broly (Told you about cliche)
Mother: Unkown (WAI I NO KNOW MY MUM?!)
Race: Full-Blooded Saiyan
Personality: Sometimes Happy-Go-Lucky.
Traits from father or mother: The only thing he has, is getting mad easily. ( #triggered )
Transformations: Canon: Kaio-Ken, SSJ, SSJ2, SSJ3, SSJ4, Grand Super Saiyan, SSJ5. Non-canon: SSJ Rage, SSJ Rose, SSJ Blue, and LSSJ.
Bio: Never really getting to see his mother, Damion often trained with his father Broly. His brother was shy, and never got into fighting, until he was about 8. Back then, they only had one thing on there mind, and it was Kakarot. Broly told them about Kakarot, but after Broly fought Gohan and Goten, he went missing. Damion, and Broly JR. moved into Toki Toki city, which is now ConTon city. That's where he met Nakusu JR. , and his family. When Damion found out Goku was Kakarot, and Gohan and Goten killed his father, him and his brother were PISSED. That was the day they both achieved SSJ. As known, they lost the fight easy, but after that Goku offered to train them. They took the offer, and made it all the way to SSJ3. (JR. Got to LSSJ3) Damion was Trunks' assistant, so he tinkered with time a few times. One of those tinkers gave us the retarded Zamasu we all know and love, and the Good-Guy Goku Black. After this, Zamasu trained Damion and JR. JR. went missing for 2 years, and none to hear of him since. This is the part were the O. Kai Rage arc. comes in.
Broly JR. and part of this boi, was created by my friend, of the same name on G+. You should check the dude out, he's cool.
