The tag alias #78173 w.d_gaster -> gaster is pending approval.

Reason: They refer to the same character, yet we have two separate tags for him.

Idk about this one. *gaster* -gaster -w.d_gaster shows other characters and artists with 'gaster' in their names. Might be worth looking into a disambiguation.

Honestly, the Gaster tag should probably either be disambiguated or aliased to whatever tag is currently applicable for insect abdomens.
