Alastor of Hazbin Hotel is probably Gabriel - because as angel of messengers ....he's patron of radio broadcasting. White stags /hind are also messengers & tied up with Saints too, so maybes 🧐
Adding that I realized this after replying to a thread on the show Supernatural on Loki/Gabriel. Interesting things in movies with 'Gabriel' were going on -Van Helsing (2004), where Van Helsing is alluded to be Gabriel, portrayed by Hugh Jackman; Constantine film in 2005).
I think because it might be fallout from 2000, loads of Christians going "it's Armageddon!" & Gabriel will use a trumpet to call home the faithful according to some lore.
