Implicating god_of_hyperdeath → asriel_dreemurr
Link to implication

Reason:

Different form of same character. If we're not implicating forms to characters any more then add implication:
god_of_hyperdeath -> undertale

EDIT: The tag implication god_of_hyperdeath -> asriel_dreemurr (forum #240001) has been rejected by @bitWolfy.
