Mechanical Bakugan (メカ爆丸, Meka bakugan?) are Bakugan that were created artificially in labs by the Vexos, namely Professor Clay. These Bakugan have a mechanical appearance, and resemble mechanized animals. After their creation and their prototype, the first Mechanical Bakugan, Ventus Altair had its bugs worked out, Mechanical Bakugan became commonplace in the Vexos with several of the brawlers having Mechanical Guardian Bakugan and the majority of them having Mechanical Bakugan Traps.
Early Mechanical Bakugan tend to spin like a top when they are thrown unlike normal Bakugan which roll like a ball when being thrown. These Mechanical Bakugan have spinning rings inside their body in their Bakugan form; Examples include Altair, Hades and Cyborg Helios.
All Mechanical Bakugan cannot talk (with some only being voiced by AI programmed to them) while half-mechanical ones like Cyborg Helios can. The new and improved Mechanical Bakugan such as Aluze, Macubass and Dryoid lack supporting mechanical Bakugan Traps as well as spinning chest pieces compared to their earlier counterparts. However, the only new Mechanical Bakugan that has a supportive device is Farbros. The Assail System and Farbros can also combine.
Mechanical Bakugan often have dots patterns in their ball or Trap form. Sometimes the dots pattern are also shown in Bakugan form. Some of them have diamond patterns in their ball form such as Altair. Most of the Mechanical Bakugan have a silvery body in their ball form except Farbros and Dryoid. No Mechanical Bakugan Traps have silvery bodies like that of a normal Mechanical Bakugan.
