Donatello's Valedictorian class: the smartest whizz kid cartoon and Anime characters

[The Great Saiyaman]

No matter which version of the TMNT franchise you take, Donatello is always depicted as the technological genius of the team, there's nothing he can't built, no computer he can't hack, no complex mathematical problem he can't solve.

But there's more whizz kids in cartoon and Anime series and I figured it'll be fun to start a thread about them.

First up: Skuld from "Ah! My Goddess"

Skuld is the goddess of the future and although with her being a deity, her actual age must be several eons, she has the appearance and the behavior of a twelve year old. Which means that she's a brat and not beyond throwing tantrums if she doesn't get her way. (Or even worse if somebody has the Audacity of calling her a kid.)

Skuld's divine powers manifest in her being a technical genius, there is an episode of the series in which she participates in a Battlebots competition with a mech which she made completely by herself using only the stuff she found at a scrapyard. In another episode when she was drafted to play in a softball match, she made a jet powered softball bat with radar guidance so it was impossible NOT to hit a home run.

She apparently has teleportation powers too, she can reach inside her shirt and pull out the most ridiculous stuff, from hand grenades to Bazookas and all kinds of pliers,, tongs, hammers, soldering irons and the likes.

Can't have a Thread like this without Edd "Double D" of Ed, Edd, N Eddie

Double D isn't your typical nerdy kid, he's very neat and precise, very much keen on thinking something out completely and very much a neurotic wreck. He's also the one who makes these incredible devices from things which should never work as proper construction material. And he's a virtuoso pedal steel player even though he says that he hates that instrument.

Come to think of it, Double D and the 2012 version of Donnie have quite a lot in common, such as the fact that they can launch into analysis rants at the drop of a dime, gets flustered around girls (Nazz with Double D and April with Donnie) and tend to get very distressed when others (Ed and Eddie in Double D's case, Raph and Mikey in Donnie's case) mess around with their inventions. Oh and they both have gap teeth.

Staying with the Ed's "Cowboy Bebop's" Radical Edward is next on my list.

Despite the name, Radical Edward is actually a girl, one who is extremely dexterous and Rubbery. A free spirit to a ridiculous degree, she randomly rambles about everything or goes into a wild rampage the next moment.

Radical Edward tying with her toes.
But despite her randomness, she's actually extremely smart and calculating, there's no computer in the known universe she can't hack and she can think of some very complex battle plans on the fly, nothing escapes her attention.

Then we have Sokka of "Avatar, the last airbender"

Sokka is the odd one out in this list, he doesn't have a technical genius but he makes up for that with having a very well developed practical imagination, when working with craftsmen it was Sokka who invented the hot air balloon, the submarine and several more technical advances in the Avatar world.

Within Team Avatar, Sokka is always the one who comes up with plans and schemes because his practical imagination always sees him through. although there also have been a lot of plans which went awry.

Okay then, feel free to add more.
