Personally, I found body fusion in which the individual characters are fused but retained their characteristics to be a creepy idea. I don't mean like when they fuse into a new character, like how Yu-Gi-Oh handled fusions, or something like Steven Universe's fusion dances (which by the way was surprisingly not creepy until they showed the ugly side of it). I mean something like this:
In case you don't know about the Spongebob one, that one is due to the teleporter mishap by Sandy, where Spongebob was teleported between Squidward's arm, and bringing Spongebob back to her caused Squidward to be teleported, resulting in the fusion you see above. The episode did have a worse fusion later on that I suggest saving your eyes from seeing, unless you are that curious.
You might not know the picture on the left, but it's from Donald's Quack Pack, which have the Duck triplets (Huey, Dewey and Louie) being teenagers. Anyway, that image is from the episode "Pardon My Molecules", where there is a machine that fuses two things and it was used to fuse a washing machine and a television earlier. Huey and Dewey ended up in the machine to hide from their pursuers (Louie hid behind the fused appliance) and an unknowing and unintentional action by their pursuer fused them to the side. The same episode also has a fusion that I found equally creepy: one character's face fused with an abstract painting, giving him a very odd look that I can't imagine how it would look in real life.
Perhaps the reason I find these types of fusion to be horrifying is perhaps stemmed from the fear that something similar would happen to me. I know it's mostly fantasy, but when something like that happened, I imagine that it's very difficult to reverse. I imagine this is something people don't find horrifying, but it certainly did it for me, but I got over it unless a new idea comes up, like how in Adventure Time, there was a story explaining Magic Man's mayhem where he fused the limbs (both arms and legs) of the people in Mars (I don't believe the scene was depicted as a present event or a flashback, but that would have been a nightmare to see).
