Kaiketsu Noutenki (快傑のーてんき, Kaiketsu Nōtenki), is a series of tokusatsu fan film parodies produced by Daicon Films (now Gainax). A parody of the 1977 Toei superhero show Kaiketsu Zubat (created by Shotaro Ishinomori), the title hero of this series has the same exact alter-ego, Ken Hayakawa, only he is a comically fat fanboyish young man wearing the same exact gringo cowboy attire. As Noutenki, Ken Hayakawa is decked out in a pink & red jumpsuit (with a "no"/の on the chest), fixed navy blue galoshes, blue gloves, white hood and a yellow crash helmet. He rides a fixed scooter.

Ken Hayakawa/Noutenki is played by Yasuhiro Takeda, who also produced this series, and went on to produce many of Daicon/Gainax's projects.

"Noutenki" is the Japanese word for "scatterbrain".

Bloopers/Outtakes (especially with the special effects sequences) are shown during the closing credits of each episode (and consequently, the credits sometimes deliberately went almost out of focus).
