Machine Dragon

Machine Dragon (機竜; kiryu) is a family in the Battle Spirits trading card game premiered in BS01. Machine Dragons are primarily Red, with some of them being White. In terms of design, they are mechanical, armed dragons or dinosaurs. Not to be confused with the primarily White Armored Dragon family. It is also worth noting that instead of Spirit, this family is very frequently assigned to Braves.
In the Grand-Lolo era lore, Machine Dragons are artificial beings created by the Dragons to counter their enemy, the Terra Dragons. They caught some of the Terra Dragons, and changed them into Machine Dragons using the machine parts from White World that washed up in the Red World. 
Despite being a family introduced in the first set, it is far from being the focus as a family for supports, and has purely been serving as a family of Braves for a long time. It wasn't until the True-Rebirth era that the family was finally chosen as the spotlight family in main set, and received its first wave of family support. The deck is mainly Red with a slight splash of White, and relies on the new mechanic Mirage. The deck is a control-heavy deck, with various means to destroy nexuses and grandwalker nexuses. It also comes with BP destroys that pierces through armor and immunity, and aims to finish the game with The CosmicCruisingDragon Astra-Dragon's life burn. 
In the lore, the True-Rebirth era Machine Dragons are members of the Dragon Crusaders (ドラゴンクルセイダーズ), a vigilante from the future that travels through time with Polluc to seek the Oracle Spirits, in order to save the future world. 
On the collaboration side, cyborg dragons are commonly categorized in this family.
