Goku Vs. Oregon

Goku first encounters Oregon in the future timeline when Trunks notices something strange in the sky and all they could see was a man floating above the cities absorbing the energy from the planet.

Oregon notices the Super Saiyans and challenges them to a fight one on one to test their strength and power because Oregon is too a Saiyan but one far more powerful then anyone could imagine. Goku was the one Oregon picked first and the fight had begun but in a matter of minutes... Goku was down. Goku had even transformed into Super Saiyan 3 form to try and stop Oregon but it was not enough. Oregon used his Spiritual Palm attack which blasted Goku into the floor.

Vegeta Vs. Oregon

Vegeta in rage attacked Oregon as Oregon blocked and dodged every one of Vegeta's attacks. Oregon then pummeled Vegeta and Stamped on his stomach.

Gohan and Trunks were speechless as Oregon destroyed Goku and Vegeta and the only option for them was if they did a fusion. This created the form Truhan which rated a power level of 3,500,000,000. Truhan fought Oregon landing a few hits but Oregon was on top smacking Truhan around and using ki balls which exploaded on Truhan when he got close.

After a long fight, Goku and Vegeta transformed into Gogeta and fused with Truhan to makethe supreme being. Goku, Vegeta, Gohan and Future Trunks became one being known as Gohantaks

Gohantaks power level: 16,700,000,000

Gohantaks Vs. Full Oregon

Oregon once seeing this transformation and viewing it's power level decided to use his fully power by powering up into a Super Saiyan but it seems it was far greater then the super saiyan ability. Oregon became Full Saiyan, a form in which you cannot change back into a normal saiyan which will mean that you would need an unlimited supply of energy that broly seemed to have. It was Oregon's only chance of beating Gohantaks.

The final showdown had begun between Oregon and Gohantaks. Oregon started off by using turning the planets atmosphere into pure energy that Oregon could use in his attacks but before he could, Gohantaks landed a devistating blow to Oregon's body which stopped him. Gohantaks then used the Mega Kamehameha wave and Oregon used his Spiritual Blast which the moves were even till Gohantaks boosted to Super Saiyan form which destroyed Oregon's Blast and destroyed Oregon himself.

Full Oregon power level: 14,000,000,000

SSJ Gohantaks: 20,000,000,000
