Fencer runs extremely fast and battles with its four bladed legs. Blinding lights shoot from its center eye to stun challengers during battle. Its long whipping tail has a blaster on the tip that can rip through opposition. Fencer has extremely strong pincers that are impossible to break free from. After combined with Cyborg Helios and other Mechanical Bakugan, Fencer is the tail of Maxus Helios, giving him even more Pyrus power.
By putting the little peg on Fencer's neck a little opened, you can do an alternative form of Battle Unit Mode by combining it with Viper Helios, Turbine Helios, and Cyborg Helios, without the use of Metalfencer.
On Bakugan Dimensions, Fencer's attack used to come from his pincers, but it was later updated to come from his tail.
