NEEDLESS/Shout Out

NEEDLESS has several Shout Outs.
- Holy hand grenade.
- The settings itself seems to be ripped off directly from Hokuto no Ken: wasteland as far the eye can see dotted with ruined high-rise buildings.
  - To further drive this point home, the narrator of the opening segment is Kenji Utsumi, better known as the voice actor for Fist of the North Star Big Bads Raoh and Kaioh.
- If you didn't know when the NEEDLESS manga started, you might think that there are a fair number to Gurren Lagann.
- Mio uses a giant stuffed animal to do a variation on the Kinniku Buster.
