Jesse

Jesse Gilbert is just a normal 13 year old brawler who likes to hang out in bakugan interspace. He bought a virtual house in bakugan interspace and is ranked number 13. One day he meets Ren Crawler, who is very friendly to him. Ren is a legend and everyone knows the story of how he helped beating emperor Barodius. Jesse is not a bit wary when Ren asks him to go to his home and talk about stragety. Once at home, Ren asks him what kind of bakugan he uses. Jesse says he uses a Darkus Reaper. Ren tells him about Linehalt and the two of them quickly befriend each other, although that is what Jesse thinks. When he's not paying attention, Ren quickly grabs an control horn and puts it on Jesses forehead. Jesses eyes start to fade and he asks:"What can I do for you, my lord?" When it turns out the control horn is a succes, a few gundalian men come into the house. The house is thouroly modernized. Jesse is brought to Gundalia were he gives his bakugan to Kazarina. Kazarina uses some power of the silent orb to power up Reaper and create Death Reaper. Jesse then returns to his house on earth and gets the order to recruit six more humans for his group.

When Jesse is walking in bakugan interspace, he meets a group of six 11 year old boys, who call themselves The Core. Jesse challenges them to a brawl. They all lose to Jesse, but Jesse is friendly to them and gives them back their bakugan. He asks them to come along to his house to talk about stragety and bakugan. The boys gladly follow him, thinking they'll get some good advice from the number 13. When they are in Jesses house, they are amazed by all the high-tech available. Without them noticing, Jesse locks the door. One by one they get a control horn on their forehead.

Jesse is the leader of The Core and has climbed all the way to become number 2. Only Alice tops him. From this moment on, Jesse doesn't get any orders and thus, stays in his house.
