I can't believe they opened a children's cartoon with a satanic ritual: 1.23%
Count Duckula is an interesting character to discuss - he, like Danger Mouse, is an icon in the UK, almost on the same level as British characters who Americans would be more familiar with such as Wallace & Gromit or Peppa Pig, beginning as a blood-sucking, fame-seeking villain in Danger Mouse's show and then being quite literally resurrected as a vegetarian anti-hero with a teleporting castle. He also has a peculiar spot in Nickelodeon history, as the first cartoon Nickelodeon specifically commissioned rather than just syndicated, following the success of Danger Mouse on Nick in the Silver Ball years. In terms of guests, this gives him a peculiar place in NASB - being, by technicality, the first Nicktoon! I do think if he does get in, it'll probably be alongside Danger Mouse given how intertwined those shows are (Duckula still appears in the recent DM reboot) and DM's slight popularity edge. That being said, the NASB devs have made it pretty clear they don't care too much for being a comprehensive Nick history guide, so that shoots in the face of almost everything Duckula has going for him

I've grown a bit more iffy on guests as a whole with time - while I doubt Duckula would be as much as a Timmy-level price investment, let alone a Goku or a Doug, there are those floodgate concerns and such - that being said, this character is a fun part of British culture I'd love to share with others, and I think a history pick in NASB would be incredible, but even then - with the Silver Ball and Pinwheel puppets around, they don't really have to dig into guests to do that.

Arnold is a Nicktoon icon. Even if you got into Nick after his show was cancelled, that football shape is instantly associatable with Nickelodeon. Arnold is also a pacifist. A pubescent, thin-bodied Buddha who wants to help everyone, and is regretful when things can't work out that way - I'll briefly get into my personal thoughts on this in the Want section - but it's clear from him being sidelined 3 times that Ludosity may not want to budge on this trait regardless of fan demand, or maybe even just don't see the moveset there that so many others do. That being said, he does get extra points for being well, a Nicktoon icon.

Like... what's the point?? His show is represented, and the only reason anyone gives for wanting him in is iconic factor rather than his potential moveset or fun make-believe situations. I don't think it'd be breaking the character to have him fight in this silly non-canon sports game or anything, at least not any more than giving Garfield movement tech or allowing Michelangelo to team up with Shredder against Leonardo, but I can't really see much reasoning for or against him, which is probably worse than just being a decent idea with a lot of downsides.
