The bakugan answered im not sure and i have heard many stories about humans and they bonds with bakugans i always dreamed of battlign side by side a brawler and i am asking would you be my brawler.Gunz was so excited he said yesssssssssssss i loved to we going to be great and his name was iron dragonoid.Iron dragonoid said that he would try help get gunz out of new vestrioa but it truns out thathe wasnt the only human in new vestrioa.He met a whole bunch of humans there.They had a group called the bakugan restience Gunz joined them and stared traing durign his time traing he becamed stroger and stronger he was now stronger than the leader and he became the new leader.Now beign the strongest brawler aorund new vestoria boared him beacuse he had no challange thats when he travelled and found him self in guardian where he found a next bakugan named leonidase there were many challanges in guardian he spent years traing there but somehtin terriable happen gunz brother frazer died in a brawl.
