By the wiki definitions, fusion and chimera are the same and should be combined into one tag. I'd suggest using fusion, which allows chimera to be used for posts currently under chimera (creature), removing the qualifier.
Tangentially related: merge contains posts depicting aquarionmecha pilots having orgasms as a consequence of combining their mecha (gattai). But since the act of combination itself is not actually depicted, I'd argue that the tags merge and gattai should be removed from these posts.
Is there a point in keeping a distinct chimera tag though? I also like fusion better because the word chimera has creature connotations. There are also plenty of posts with more than 2 characters in a fusion: fusion chartags:3..
-1 to this. The chartag search has always been horribly inaccurate to begin with, and the fusion chartags:3.. is no exception. At least 9 (56% of the images that aren't already tagged chimera would not qualify for that tag, as it's two characters fused and then a 3rd person present or a similar setup. 2 of the remaining then may not even qualify for the fusion tag, post #266964 and post #464787. There is also a post like post #221154 where two characters fuse, shaped shift through several other named characters/creatures and then finally emerges as one normal 2 character fused being.
Further concerns are what if an image depicts several unnamed characters who fuse together, the chartag search will bring nothing up.
I wouldn't be against renaming what's under the current chimera tag to something like chimerism.
I didn't say that the chartag search was an alternative, I meant to say that the fusion tag already has pics with more than two characters fused. So we have:
fusion: 2 or more characters fused chimera: 3 or more characters fused, implying fusion
Is that chimera tag really necessary? And if so, why not define yet another tag for 4+ characters?
Because typically with 3 or more characters it generally becomes the same thing of one central character with only 1 or so traits from all the other added characters.
edit: Additionally a fusion of just 2 characters usually ends up with a fairly equal distribution of characteristics between the two characters in comparison.
