Mechtogan Control Bracelet
From The Bakugan Wiki
Mechtogan Control Bracelets (Unofficial name) are used by Anubias and Sellon to control Mechtogan in Bakugan: Mechtanium Surge. They bear a resemblance to the newer model of BakuMeter.
They can be used to forcefully summon a Mechtogan at will, with the downside of hurting the wearer whenever the Mechtogan tries to break free, or if it takes damage.
