- Memetic Hair: Astro Boy in all versions.
Astro Boy (manga)
- Germans Love David Hasselhoff: Australians make up a large fanbase, partly due to being one of the few countries outside Japan that got the 1982 series.
- I Want My Jet Pack: Despite nuclear energy being utilized rapidly for civilian purposes today, as Tezuka hoped, we're nowhere nearing jetpack stage.
- The Woobie: Astro, during the retelling of his origin in the Scara arc.
Astro Boy (1963 TV series)
- Woolseyism: The original title theme was instrumental. When NBC dubbed the show for their English audience, lyrics were added, sung by a children's chorus.
Astro Boy (1982 TV series)
- Macekre: The English dub is abysmal, with the dialogue sounding like it was made up on the spot by the voice actors.
Astro Boy (2003 TV series)
- Jerkass Woobie: Dr. Tenma.
- The Problem with Licensed Games: The PS2 entry by Sega ended up being incredibly bland in terms of gameplay, among other problems.
- They Wasted a Perfectly Good Character: Atlas. His first 2 episodes built him up as the perfect Shadow Archetype to Astro. Then, he's sent adrift in space for thirty-something episodes, only to be brought back for one Redemption Equals Death episode, and is brought Back from the Dead to be a minor player in the Grand Finale.
Astro Boy: Omega Factor
- No Problem with Licensed Games: This game on the other hand was much better received. Treasure knows their stuff when it comes to making fun games.
- That One Boss: Carabs, Pluto, Sharaku.
Astro Boy (2009 film)
- Anvilicious: President Stone will say it again and again: he is the president, and for Metro City to depend on him he needs to make a war.
- Big Lipped Alligator Moment: The attack of the giant alien at the end whose only purpose was to give a shirtless Astro an action shot, probably.
- Coming-Out Story: Astro Boy's secret of being a robot resembles most Coming Out Stories, especially the nighttime scene when he almost "comes out" to Cora.
- Complete Monster: In this Animated Adaptation of Osamu Tezuka's manga, President Stone, at first seeming to be nothing more than an impulsive and childish leader, is slowly revealed to be far more wicked. Stone commissions Doctors Tenma and Elefun to build him a super robot, known as The Peacekeeper, and plans to use it to wage war with the harmless Surface-Dwellers. Despite the scientists' pleas, Stone uploads a highly dangerous power source into The Peacekeeper, resulting in the death of Tenma's son, an accident Stone barely acknowledges. Learning Tenma rebuilt his son as a robot and used another highly effective power source to give him life, Stone tries to capture or kill the boy to extract the power source, causing copious amounts of destruction to the city in the process. After detaining the child, now known as "Astro," Stone strong-arms Tenma into removing his power core, which would kill the boy. When Tenma refuses, leading to Astro escaping, Stone orders both Tenma and Elefun arrested and plans to have them executed. Stone then reactivates and takes control of The Peacekeeper, starts destroying the city looking for Astro, and prepares to crush several of Astro's friends, all children, trying to draw him out. Doing everything in the hopes that he would be re-elected, Stone was power-hungry, delusional, and sociopathic for an ultimately petty reason.
- Hilarious in Hindsight: Donald Sutherland plays President Stone in the film. Sounds a lot like President Snow, now does it?
- Older Than They Think: Quite a few people claimed that giving him butt lasers was disrespectful to the source material and Astro's creator...
- The Problem with Licensed Games: The tie-in game tried to borrow gameplay from Omega Factor and failed miserably.
- Retroactive Recognition: Grace, the girl Cora gives a chainsaw to, is voiced by Elle Fanning.
- WTH, Casting Agency?: In Brazil, Astro Boy was voiced by this guy.
