(I don't own Yugioh GX)
(Ok so here is my idea, Jaden has a younger brother that is 4 years younger than him. And just to get it out of the way, no it will not be like Zane and Syrus. But I will be scraping most of season 2 to make my own story, but all the exchange students, but not viper will be attending, and if I make a season 3 they will most likely stay. Also another thing, if you would like to request an OC which there will be, if I get my way at least 3 or 4 OCs that stay throughout the story. Oh yeah one last thing Yubel is kinda just gonna pop up here and there because her spirit is fused with not only Jaden's but Ashton's to. So enough of my rambling let's get this started.)
"Hello, Jaden, Ashton get up its Exam Day!" Yubel practically screamed at them. That didn't work so Yubel got an idea. She called on Elemental Hero Ocean and told him to surprise them. Within the next few seconds Jaden and Ashton were up. "OH MY GOD REALLY YUBEL" Screamed the Yuki brothers in unison. Yubel said back "It's Exam Day change and get up, both of you." Which surprised Ashton since he was too young to join the Academy but still, he listened. After that they said goodbye to their parents and left their apartment complex sprinting.
While running they ran into someone, they said sorry and got up. It was Yugi Moto! They were amazed as they looked up and saw him. All they said was "Oh sir I am so sorry please forgive us." Yugi let a small chuckle escape him at this. He said "No, it was me and here I believe these are yours." In which he handed a card to each of them To Jaden was a winged kuriboh and to Ashton was a card that depicted what looked like an elemental hero but went by the name of Animal Hero Slitherick. It had a picture of what looked like a gigantic snake. With mad attack power of 3000 attack and 1500 defense. It fit his deck of animal hero's. The boys thanked him with awe and ran off again. They made it just in time for last Min. signups. But at first they wouldn't let Ashton sign up and that made Jaden mad, when Jaden gets mad his eyes turn to Yubel's. When that happened the guards kind of just let him signup.
(that's chapter one, I know VERY short chapter I just want to post this and see if I can get any ideas for OCs or cards or story plots.)
