In the future, basketball is played by giant robots called Bigfoots and the wealthy elite live on the moon. Dan PJ is a cocky young boy who lives on the planet Earthdash and makes a meager living working as a delivery service. He dreams of someday bringing his disabled sister to the moon to give her the medical treatment she needs. Dan also despises the boring playing style used by official Bigfoot Basketball, so the first chance he gets he crashes a game to show the world how it's really done - destroying the arena and being thrown in jail in the process! However, by the time he's released, Dan's story is legendary, spawning countless imitators who smash up the city in their Bigfoot duels. All Dan's got to do is fend off his rivals, try desperately to keep his business afloat, and aim for the moon!
Simon lives a boring life in the underground village of Jeeha, where his main job day in and day out is to dig tunnels. His close friend Kamina, however, longs to bust out of their oppressive existence and reach the surface world where open skies and adventure await! One day, during his usual digs, Simon discovers a robot with a big face buried amongst the rocks. No sooner has he shown Kamina his mysterious find when two beings from the surface crash land into Jeeha Village - one is a gun-toting woman calling herself Yoko and the other is a terrifying mecha piloted by a Beastman! Seeing their chance to escape village drudgery, Kamina rallies Simon and Yoko to defeat the invader using their new robot, Lagann. However, upon breaking out onto the surface world, Simon, Kamina, and Yoko encounter enemies more powerful than they could have envisioned. Their fight for adventure just turned into a war for the survival of the human race - will their lust for freedom hold out against such terrible odds?
Explosive, comic, highly stylish mecha silliness filled to the brim with overblown shonen melodramatics - to say Basquash wears its debt to Gurren Lagann on its sleeve is an understatement; from the pet creature our hero has (who pokes around the girl's breasts when they find their mecha) to the individual eye-catches, Basquash! is just TTGL with CGI, and basketball.
From the Animation to the Mechs and use of extreme over the top action, Basquash and Teggen toppa Lagann share copious amounts of these. Also you have large amounts of Ecchi and Breasts sharing the screen here.
