This Hazbin Hotel collage is of Alastor and Carmilla Carmine, after I saw role swap AU YouTube videos of the two swapping roles with one another by Odette_Carmine1, (who has given Odette and Clare antlers and button deer noses so they would look like daughters of Alastor, while Carmilla with Alastor's was kind of creepy,) I got inspired to make a collage on them. The other reason I made this collage is due to the headcannon history @elsa-fogen has hinted between the two in her AU comics of Alastor, I recommend checking them out; though her Incompatiable Frequencies comic story is 18+ from having some heavy trigger themes in it, so read that one with caution. While Alastor and Carmilla's Italian voice actors (Nanni Baldini and Antonella Baldini) being siblings might get others to view these two overlords as siblings as well.
RadioGun has also been called Alarmilla, Carmilastor, RadioWeapon and RadioBallet.
