Fusion and death | DBM (Extended Discussion) (2024)

I'm not entirely sure about the Fusion Dance, but for the portaras, didn't Old Kai sacrifice his life so that Goku could restore his? Old Kai is the fusion of his original form and the witch, but post death, we see him in the world of the Kais (and in a gag scene in the anime, lol)

According to DBM, Old Kai enchanted the earrings to work for Goku and Vegeta. Since the fusion worked for those two mortals, it is safe to say they obey the same rules as Old Kai. Meaning Vegito is dead if he gets killed, no defusion.

What'll make a good "what if" is when he meets King Yemma and is told he does not deserve to go to heaven bc of his Vegeta half and his violent tendencies.

His Kid Buu reincarnating into Uub wish was not granted precisely due to that, so I think that same criteria would apply.

Oh yeah, forgot about old kai... guess the question is just about the dance method then. I'll revise it.

Personal opinion:

Fusion Dance - the fusee splits into components, still alive.
Potara - the fusee dies and leaves a corpse. Components' souls split in Otherworld.

My headcanon is both methods of fusion are literally creating new bodies: Gotenks isn't, say, one arm of Goten's and one arm of Trunks. Not even necessarily Goten and Trunks' bodies liquified and poured into a Gotenks-shaped mold. Gotenks is a completely new body that just happens to have 100% Goten's DNA and 100% Trunks'.

Maybe it's because of Hirudegarn smacking Gotenks in two in Wrath of the Dragon(which is a Toei idea), or maybe it's the temporary nature of the fusion dance, but I think when the fusee is "killed" the magically-created body dissipates and the two fusees remain. Maybe they're drained, but still physically unhurt. This is why I didn't have a problem when Gotenks got hit with carbonite and eventually defused, though many people thought it didn't make sense. I see it as the two fusees' actual bodies being magically stored in hammerspace somewhere until the fusion runs out--whatever state they went into the fusion, is the state they'll be after the fusion.

Since Potara's permanent, though (YES IT IS, SUPER NEVER RETCONNED IT, LALALA CAN'T HEAR YOU) I think it'd leave a corpse. What happens to the components afterward varies. If U18 Vegito died against Buu, Goku and Vegeta would show up in Otherworld. In U16 Vegito's case, if he were to die a Vegito soul would show up in Otherworld.

Yeah, Vegetto is interesting because he states that he's neither goku nor vegeta and that he was literally born with his fusion and is his own entirely unique person. So what's up with his soul? Is there a unique vegetto soul that would go to otherworld or would they split as you suggest. If there is a vegetto soul then that would mean goku and vegeta's souls were essentially destroyed with the merger (or liquefied and poured as you suggested). If vegetto were to have his soul split with his death that seems almost as bad as goku and vegeta's being destroyed as this unique person basically has no soul of his own.

I'm going to lean towards he has a new fused soul that will go to otherworld as is and goku and vegeta's unique souls are simply gone for good. Although I can certainly see it being possible that death could somehow break the fusion for the souls.
