Implicating asriel_dreemurr_(god_form) → asriel_dreemurr
Link to implication

Reason:

Specific form of base character

EDIT: The tag implication asriel_dreemurr_(god_form) -> asriel_dreemurr (forum #280478) has been rejected by @bitWolfy.

-1, they look different enough to be tagged with different character tags. It would also become impossible to avoid posts tagged asriel_dreemurr when trying to only search for their god form, since all of the latter would also have the former's tag. asriel_dreemurr_(god_form) -asriel_dreemurr wouldn't work.

The tag asriel_dreemurr looks to me to be for his young form so I don't agree with this implication.
It would be nice if there was a tag only for young-form, but I can't imagine that coming true.
