The problem with fusion is that it becomes an unwieldy plot device. It's good to have variety but not at the cost of tension or believability to the story. Think about it. Let's pretend fusion always existed. Raditz would have been killed easily by a yamcha/ten. Same with Nappa and Vegeta. Then on Namek Krillhan would take out the ginyu force and Gogeta would have wiped out Frieza. Do you see where I'm going with this? The fights are always a sure thing unless you make the villains insanely powerful. But at that point our main characters no longer matter and the show is about Gogeta, Gotenks, etc. Or they go the route of the characters refusing to fuse out of pride, despite their home and loved ones being in danger.Doctor. wrote:Fusion is a technique that brought variety to the Dragon Ball universe. It doesn't make them look like pricks, it gives them character development in some ways. It's good that it's still around to make characters like Goten and Trunks somewhat relevant.
Adding an occasional creative villain here or there will not remedy the overall problem. At some point, the Z fighters need to face a more powerful opponent for the story to progress. When that time comes, they might as well fuse and make Gogeta the main character. It was an interesting concept but from a narrative standpoint it does not work for a story like this.
All they have to do is say SSGs can't fuse, and it can all just go away.
