S.P.D.! DekaBreak!"
―DekaBreak's roll call[src]

Tekkan Aira (姶良 鉄幹 Aira Tekkan) is DekaBreak (デカブレイク Deka Bureiku) of the S.P.D. and Dekarangers. His nickname is Tetsu (テツ/鉄). His designation is the roman numeral VI.

Character History


A super elite from S.P.D.'s Tokkyou division who was sent to earth to fight the Hell Siblings, an elite group of Alienizers who have already destroyed 79 planets, Earth being their next target. An Alienizer named Genio killed Tetsu's parents when he was about five years old. Tetsu was raised by the Space Police off-planet. He pilots the DekaBike. His catchphrase is "Nonsense!".

His fighting style is the Seiken Accel Blow, a martial art style of that all Tokkyou officers use when battling Alienizers and utilizes the BraceThrottle for various effects.

In episodes 26, 45, and in Magiranger vs. Dekaranger, Tetsu dresses up in drag to disguise himself. There's some indication that he is interested in Swan-san. In addition, he treats Umeko like a baby sister. He also develops a strong friendship with Ban, calling him "Senpai" (veteran), and promptly replaces him as Jasmine's partner when Ban joins the Fire Squad.

Some time around the conflict betweenFire Squad andAgent X's Alienizer faction, Tekkan has given the Tokkyou badge again, thus returned to serve as the Tokkyou and double as Ban's replacement member at Earth Branch from now on.

10 Years After

Ten years after the Dekaranger's final battle against Abrella, Tetsu later became the acting commander of S.P.D. Branch on Earth after Doggie Kruger was being framed.

He secretly orders Ban to disguise as Carrie while the real Carrie is brought to the Dekabase in a remote planet by Houji in order to protect her as being witness to her dad's murder.

Ranger Key

The DekaBreak Ranger Key.

The DekaBreak Ranger Key (デカブレイクキー Deka Bureiku Renjā Kī) is Tekkan's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key, along with the other fourteen sixth ranger keys and the ten extra hero keys, were initally acquired by Basco ta Jolokia and later used by the Gokaigers. Like all of his Ranger Keys, Basco used his trumpet, the Rapparatta, to turn the DekaBreak key into a puppet to do his bidding. The copy DekaBreak was one of the first five sixth rangers that Basco showed Captain Marvelous (Gokai Red), revealing he had found more Ranger Keys. These five puppets fought the Gokaigers and were all defeated, with DekaBreak being defeated by Gokai Pink. Basco left these five keys to Marvelous.

A short while after, the first fourteen Sixth Ranger Reys, along with all the Ranger Keys of the first 33 Super Sentai, were briefly taken by the Black Cross King and turned into Ranger puppets that were fought by the Gokaigers and the Goseigers. The DekaBreak key was among ten of these Sixth Ranger Keys who fought, and were defeated by, Gosei Knight. Gokaiger Goseiger Super Sentai 199 Hero Great Battle

While in the possession of the Gokaigers, the DekaBreak Ranger Key was mainly used by Gai Ikari (Gokai Silver), who used it to fight as DekaBreak. It was also used by Joe Gibken (Gokai Blue) on one occasion.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Tekkan received his key and became DekaBreak once more.

Tekkan "Tetsu" Aira is portrayed by Tomokazu Yoshida (吉田 友一 Yoshida Tomokazu). As a child, he is portrayed by Yuta Komuro (小室 優太 Komuro Yūta). As DekaBreak, his suit actor was Eitoku (永徳).
