Ryusei Ningen Zone, better known in the United States as Zone Fighter, is a 1973 tokusatsu series from Toho, their second attempt at a superhero series. It is especially notable for crossing over with the Godzilla franchise.The Sakimori/Zone family resembles a normal Japanese family, but they are an alien family that came to Earth after their home planet, Peaceland, was destroyed by the evil Garoga aliens. To stop the Garoga army's invasion on Earth, the Sakimori family's three children, Hikaru, the oldest son, Hotaru, the teenage sister, and Akira, the youngest brother, transform into the superheroes Zone Fighter, Zone Angel and Zone Junior, respectively. Zone Fighter can also turn into a giant sentai to fight kaiju, but only for a few minutes. Zone Fighter must use several different powers to kill the Terror Beasts and stop the Garoga once and for all.The show sadly had a very short run (so short that making a paragraph on the series as a whole can't be done, or can it?) thanks partly to the 1973 oil crisis and partly due to low ratings. The show has also been criticized for being a "rip off" of the long-running Ultraman. The show is most famous for having Toho's Godzilla, Gigan, and King Ghidorah making guest appearances on the show. That's right, that Godzilla. The show has many campy moments since it was aimed at kids. Despite this camp however the show could be surprisingly violent for a kids show. You haven't lived until you've seen Zone Fighter rip out a monster's eyes, cut off its arms, shoot off its head, and then fly its corpse into space just for cheating in ring toss. There's a lot of Monster of the Week so you'll rarely see the same kaiju twice, especially given what happens to said monster.Zone Angel and Zone Junior will often help their brother recharge when he is running low on energy by shooting a beam into the capsule on the tip of his head crest or by using their aircraft called Smokey to fire a replacement capsule after the current one falls off. Zone Great, the grandpa, will sometimes help by pulling a lever which will send his energy into the sky and rain down on an attacking kaiju as a lighting bolt called the Thunder Bolt. The family friend Hideaki Obara is only human but will also lend a hand in stopping the Garoga. Godzilla will also help time to time, and the family even made a sort of "Godzilla Cave".Zone Fighter's trademark power is his Meteor Missile Might in which wristbands filled with anti-kaiju missiles are fired. Unlike the armies', they actually kill monsters and are very accurate, to the point that they even rival Showa Mechagodzilla's Finger Missiles or Heisei Moguera's Spiral Grenade Missiles. These missiles' destructive power rivals even the first Mechagodzilla's finger missiles. He can also fire a Meteor Proton Beam which can blow up a kaiju with a single blast and is used on monsters too powerful to be killed by the Missile Might Attack. He can also fire a stream of arrow shaped energy which can be either two little red stream, one large red stream, or two very short yellow ones. He can fire a Subduing Mist which acts as a sort of drug to calm down a monster, he can run at jet speed and fly. He also can make a Zone-Barrier to block projectiles or make a Hyper-Barrier to reflect projectiles back at the source.
Zone Fighter provides examples of the following tropes:
