Saiyan Younger Brother of Superman

Twelve years ago, the first spaceship brought the Kent family a superhuman son.
Twelve years later, the second spaceship brings them a Saiyan son.
A brotherhood between Superman and a Saiyan—
what kind of shockwaves will their bond unleash upon this world?
PS:
The setting takes place in a brand-new, fully reimagined American-comics composite universe, formed after the fusion of universes involving the protagonist of a previous work.
This world blends elements from:
DC films and animation
Marvel films and select comic storylines
Jackie Chan Adventures
and various films featuring supernatural or extraordinary powers
Some characters and abilities will defy established conventions, and the story will not follow original canon timelines.
Instead, it extracts major events and rewrites them from the ground up, reshaping the narrative into something entirely new.
