User blog:KuraiJack/Rival character help needed.

I need help with certain parts of the rival character I'm making for Kurai. Here's the stuff I've already done:

Species: Human.

Age: 17

Height: 6 feet.

Gender: Male

Personality: He tends to make sarcastic and cynical remarks which are usually negative, and acts as if he doesn't care whether his friends get injured or not, but his actions show that he does. In battle, he is shown to be at the same level as Kurai when it comes to combat.

Here's the stuff I need help with:

Name

Weapons

Abilities

Backstory
