- Alternate theory: The Count Duckula in Count Duckula is the Reincarnation of the one from Danger Mouse.
- That, in essence, is the same thing. Duckula is constantly re-incarnated so he is his own father many times over.
- Pretty much "unofficially official" as the creators have confirmed that the idea was that the Duckula from Danger Mouse was somehow killed. When Igor tried to resurrect his master, Nanny mistook a bottle of ketchup for the blood that was needed in the ritual. By using a veggie-based product instead of blood, he was brought back to life as a vegetarian. As he does not need to hunt vegetables as such, he lost much of his aggression and other personality traits came to the fore.
- It's actually heavily implied that, at least for 'the Count Duckula, there's actually no difference: when the current Count Duckula the __ is slain, the ritual that Igor and Nanny perform causes him to reincarnate, rather then straight-up resurrect, allowing each new Count Duckula the __ (the present Count is Count Duckula the 17th) to have his own unique appearance and personality. Of course, the Duckulas are also able to breed (sort of) like normal vampires, hence explaining both the menagerie of cousins and relatives that show up in the show (like the miserly Rory McDuckula, a Scottish Duckula) and the more bizarre ancestors (like Lady Pintail Duckula, a female vampire duck who attempted to eat Castle Duckula).
- This seems quite possible, although both Duckula's were shown as being obsessed with getting fame as an entertainer. Igor's reaction to this development always seemed to imply that it was a recent development, new to this incarnation.
- This can be explained as a product of the improper resurrection. The 16th Count Duckla (the one in Danger Mouse) was into showbiz but was still a nefariously evil vampire, so Igor (perhaps reluctantly) tolerated it. But when he was resurrected as the 17th, as we all know, the ritual went wrong. This resulted in some of the previous Duckula's traits being carried over into the new one, including his obsession with show business. Without evil in him, this obsession became even more of a driving force, and one Igor could no longer ignore.
- Presumably, the Duckula in the 2015 reboot of Danger Mouse is the 18th. He's some kind of weird composite of the 16th and 17th Duckulas, still showbiz-obsessed and a vegetarian like the latter, but nefarious and evil like the former, since he uses his powers to turn people into vegetables and eat them. He's also a Fully Dressed Cartoon Animal now, breaking the long-standing tradition of cartoon ducks like his forebears not wearing pants.
- Jossed by the mere fact that the new Danger Mouse series is clearly a reboot, despite claims to the contrary.note It would only work if it were the same continuity, which it clearly isn't.
Count Duckula can't get hurt by the sun BECAUSE he's a vegetarian.Ok here's a wild one, but what if the fact that he refuses to drink blood and become a traditionally vampire is protecting him from the sun. Seeing as traditional vampires and even the stone one we see in "a dark and stormy night" dies when coming to contact with the sun and our count is anything but traditional.
