Blue Flare

Blue Flare is a cold-blooded army in Digimon Xros Wars.

Kiriha Aonuma
Kiriha Aonuma (蒼沼キリハ) is the General of the blue "Blue Flare" army. Kiriha is described in V-Jump magazine as "cold and calculated" and said to "eliminate enemies, in order to spread his power and influence". He is someone that shows very little empathy towards others including that of his own Digimon, as evident by his treatment of Golemon. He seems to be obsessed with strength and shows interest in Taiki Kudou because of his strength and abilities, wishing to add him to his own army. While he has shown to be helpful toward Taiki and his friends it was only an attempt to persuade Taiki to join his army, and when his offer was declined he immediately stopped helping. He recognizes Nene Amano by the beginning of the series, and eventually joins forces with her, though he leaves her when she tries to force him to torture a defeated Stingmon for information, despite him objecting that it would be beneath him.

Greymon
Greymon is Kiriha's main partner. He looks like a blue-skinned version of a regular Greymon, but with a metal helmet shaped like a GeoGreymon's, and a cannon-tipped tail.

 * Blaster Tail: Drives its tail into opponents for 360° around itself.

Golemon
Golemon is a golem Digimon that is used by Kiriha to Digi-Xros with MailBirdramon and give it a rock hammer tail. After Golemon injured Xros Heart, Kiriha tossed Golemon away, believing that it was useless and was of no use to him, infuriating Taiki.

Cyberdramon
Cyberdramon is an alien-type dragon Digimon.

Cyberdramon first appears when Kiriha releases him from his X Loader in order to attack Blastmon. Alongside Nene's Sparrowmon, Cyberdramon manages to inflict some damage to Blastmon, but Blastmon soon gets fed up and flees.

Deckerdramon
Deckerdramon is a legendary alligator-like Digimon who protects the Forest Zone's Code Crown, and is said to be undefeated in battle. Due to this, DarkKnightmon sought him out to join Twilight, but Deckerdramon ends up joining Blue Flare, as well as giving them the Code Crown, when he sees true love in Kiriha's heart.

While he guards the Forest Zone, he is covered in a golden aura that makes him resemble a golden idol. However, when he joins Blue Flare, he reveals his true blue-and-brown color scheme.

Attacks
 * Trident Tail: By swinging the tail he creates a shockwave to blow the enemy away.

MetalGreymon
MetalGreymon is the Digi-Xros of Greymon and MailBirdramon.

MetalGreymon is first used when Kiriha is attacking the Bagra Army in an unnamed Zone, but soon degenerates back to Greymon and MailBirdramon. He later reappears when Kiriha DigiXroses Greymon and MailBirdramon, so he can fight against IceDevimon's army in the Lake Zone, and even later helps Xros Heart to fight Baalmon while they are in a difficult battle with IceDevimon himself.

He easily defeats both Stingmon and Lilamon in the Forest Zone, but is beaten up and almost killed by an infuriated DarkKnightmon. However, MetalGreymon is saved by Shoutmon X4B. MetalGreymon aids Shoutmon X4 in his battle against DarkKnightmon, but is severly beaten by DeadlyAxemon, until Deckerdramon decides to join the battle. In the Dust Zone, MetalGreymon and the other members of Blue Flare attack Xros Heart under the command of a brainwashed Kiriha. After Taiki saves Kiriha, MetalGreymon takes part in the battle against Twilight and the Bagra Empire.

Attacks
 * Trident Arm: Smashes its claw into the opponent, a technique exceptionally enhanced in offensive power due to adding extremely high-temperature claws on top of Greymon's already mighty strength.
 * Giga Destroyer: Annihilates all of the opponents surrounding it by emitting ultra-high energy, homing laser beams at them.
