The invincible War!

Let's make a What if story...

"The Clash of legends"

What if the planet called planet Vegeta was in the invincible universe, A Viltrumite is a super-powered, warrior-like alien race from the planet Viltrum in the Invincible comic series. They possess abilities such as superhuman strength, speed, and durability, as well as a long lifespan and the ability to fly. Originally, they were a civilization that conquered and subjugated planets, but the culture later shifted to focus on planetary infiltration and the use of their dominant genes to create more Viltrumites through reproduction programs.

Along with "Saiyan" primarily refers to a fictional, extraterrestrial warrior race from the Dragon Ball franchise, known for their aggressive nature and immense power and ability to transform into different forms of power! They originated from Planet Vegeta

Goku and Vegeta are kids, it's drastically different from the original, the Saiyans are at war with the Viltrumites, it's been like this ever since Omni-Man visited king Vegeta in years ago!

Vegeta and Goku end up becoming like brothers more so then rivals due to the Saiyans not being so stand offish and brutal in this timeline however Vegeta always will be Vegeta!

The Saiyans will be placed in the timeline of these events in Invincible!

* Thousands of years ago: The Immortal is born, and the Viltrumite Empire begins its galactic conquest. Coming across another warrior race called (Saiyans)

* Decades prior to the main story:Nolan Grayson (Omni-Man) arrives on Earth, adopts a secret identity, and marries Debbie. Nolan attempts to destroy planet Vegeta however he is unable to due to the large amount of warriors that attacked him!

* 17 years before the main story: Mark Grayson is born.
* The Beginning of the Story: Mark's Viltrumite powers manifest in high school, and he adopts the name "Invincible".
