Tristan Metellus, a unique individual with the incredible ability to manipulate everything around him, was approached by the legendary warrior Vegeta for some much-needed training. Vegeta had been inspired to reach the level of a Super Saiyan God after witnessing Goku's epic battle with Beerus while Goku was in that divine form.
To get the help he needed, Vegeta turned to Whis, who had never met Tristan before. Whis noticed a strong presence of godly energy around Tristan, not realizing that Tristan had intentionally created an aura that resembled divine ki just for Whis to sense. Recognizing this potential, Tristan agreed to train Vegeta and even created a special training realm just for them.
In this mystical space, Tristan infused Vegeta with a bright essence of white ki, which helped Vegeta transform into a Super Saiyan God. After some time getting used to his new powers and experimenting with them, Vegeta was able to fully embrace this strength, similar to what Goku had experienced. In just five minutes, Tristan helped Vegeta master the Super Saiyan God form without any major issues. Soon after, Vegeta pushed his limits further and achieved the Super Saiyan Blue transformation.
Meanwhile, Goku was also training with Whis, who was more than happy to teach him due to his love for teaching. They moved to Beerus's planet, where Goku worked hard under Whis's guidance, eventually mastering the Super Saiyan God form through intense training. Whis then focused on helping Goku reach the Super Saiyan Blue transformation.
When Vegeta and Goku finally met for a sparring session in the time chamber, they found their powers were remarkably balanced, both significantly stronger than before. However, after a tough match that ended in a stalemate, Vegeta was puzzled by their equal strength and sought Tristan's help for further improvement.
Taking this chance, Tristan began a new training phase with Vegeta, giving him specially designed skills that blended seamlessly with Vegeta's fighting style. One of Tristan's notable creations was a new transformation called "Super Saiyan Blue Evolution," which made it seem like Vegeta had achieved this new state through his own hard work.
At the same time, Goku was learning from Whis about the complexities of Ultra Instinct and essential combat techniques. Thanks to these lessons, Goku managed to combine Kaioken with his Super Saiyan Blue form, though he capped it at a 20X multiplier, similar to Vegeta's recent transformation. All of this training was happening quietly while Beerus was asleep.
Eventually, Goku unlocked the first stage of Ultra Instinct, known as Ultra Instinct Sign. Meanwhile, Tristan was secretly watching and working on a custom form for Vegeta. During a break, Tristan created a Hakai orb for Vegeta, leading to an intense moment where Vegeta absorbed the destructive energy, triggering his transformation into Ultra Ego.
