Firewalker, Lefty's Monsuno is pure danger on legs. Beware of spiny tail whip lashings and vicous helpings of spewing volcanic lava. It is able to shoot lava out of the three volcanoes on its back and from its mouth.
Firewalker debuted in Underground, where it fought Charger in the subway and was beaten.
In Failsafe, its Core was taken from Lefty following a battle with One-Eyed Jack, whom had NA Man use his hammer to return Firewalker's Monsuno Essence back to the ground.
