Blue Flare

Blue Flare is a cold-blooded army in Digimon Xros Wars. Following the defeat of Dorbickmon, Kiriha and his team join up with Xros Heart.

Golemon
Golemon are golem Digimon, and Kiriha has several of them in his army. One 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.

Kiriha's surviving Golemon appear with his army when he rushes Dorbickmon's forces in Dragon Land. However, Dorbickmon, in his Darkness Mode, opens up a sinkhole beneath the Blue Flare army, then attacks them alongside his Flarerizamon, forcing Kiriha to recall his forces to his X Loader.

Gaossmon
Gaossmon are small blue dinosaur Digimon. Kiriha has multiple Gaossmon that serve in his army. He uses them to attack Blastmon's forces in the Disc Zone, in a contest for the sum of their Code Crowns, but the contest is ended when Blastmon and several of Kiriha's Digimon fall into one of the Zone's growing fissures.

Kiriha's surviving Gaossmon appear with his army when he rushes Dorbickmon's forces in Dragon Land. However, Dorbickmon, in his Darkness Mode, opens up a sinkhole beneath the Blue Flare army, then attacks them alongside his Flarerizamon, forcing Kiriha to recall his forces to his X Loader.

"MailBirdramon + Golemon"

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 Army. During the battle against Dorbickmon, MetalGreymon gains the ability to digivolve into ZekeGreymon.

MetalGreymon is later put into a forced Digi-Xros with NeoVamdemon shocking everyone especially Kiriha. However, he is rescued by Shoutmon.
