Dragon Ball: The Gogeta Chronicles.
When Gogeta defeats the dimensional demon Janemba, he expects the fusion to end like always. But something went wrong in the otherworld....the fusion is permanent. Now Goku and Vegeta are gone forever, replaced by someone who carries their memories but isn't quite either of them.
Returning to Earth as a completely new person, Gogeta must navigate the complicated emotions of two grieving wives, confused children who've lost their fathers, and a world that doesn't understand what he's become. When Kid Buu emerges more destructive than ever, killing beloved Z-fighters, the desperate wish to bring back Goku and Vegeta only confirms the impossible truth....they no longer exist as separate beings.
From the otherworld's mysteries to universal tournaments, from family dinners that seat two wives and one husband to battles that shake reality itself, follow Gogeta as he forges a new identity while carrying the legacy of two legends.
In a universe where fusion was meant to be temporary, what happens when forever becomes the only option?
