I think the "miraculous" is a pun that doesn't translate well..
If you'd transpose (not! translate..) the german Grausam into english you would get "Terrific".
Which actual meaning is "One who inspires terror" , instead of it's modern use in the english language with its connotation of magnificence.
I feel in full english his name here would be closer to "Magnificent Terror" ( or if he's cast as a pretentious idiot: Terrific the Magnificent), but then you'd give away the dad joke, or lose the pun entirely.
