Scrappy doo

There's also Astroboy's taller,thinner (and forgotten) brother (from Wikipedia) : "Cobalt (Kobaruto; "Jetto"; later replaced by a character named Atlas in the 1980 anime version) - Atom's robotic brother. His origins differ in the continuities of the manga and anime versions. In the manga, he is an inferior copy of Astro created as a replacement by Prof. Ochanomizu when he was missing and presumed scrap. In the anime version, he was a defective prototype of Atom built by Dr. Tenma, then sealed within the Ministry of Science archivesand later released. Cobalt has abilities comparable to his brother's, but lacks Astro's intelligence and common sense. Clumsy, accident-prone and gullible, he is a constant source of trouble for Atom's family (and everyone else who crosses his path). Despite these problems, Cobalt is often shown to be extremely kind-hearted and loyal. In addition to the abilities that were copied from Atom, he also shares a kind of telepathic link with his brother that gives him the ability to sense when Atom is in danger and home in his location. He originally died a heroic death at the conclusion of the Midoro Swamp story arc in the Shonen Magazine serial version of the manga, but Tezuka later changed his mind and rewrote the ending for the paperback version so that he survived."

Jackdaw the elf from Captain Britain : Even Alan Moore couldn't fix this character so he was quickly bumped off..

Tom Bombadil (eft out of the Lord of the rings movies) He speaks in a rhyming whimsical way: "Hey dol! merry dol! ring a dong dillo! Ring a dong! hop along! fal lal the willow! Tom Bom, jolly Tom, Tom Bombadillo!"[4] He has a jolly, carefree attitude, and little seems to concern him. He sometimes refers to himself in the third person, as if simultaneously weaving his own epic narrative, even as he lives it. In The Lord of the Rings he twice describes himself in his songs as: "Bright blue his jacket is, and his boots are yellow."
