Vulcan

Halfway through the series, the Savage Hammer team employ three mercenaries named Miguel, Vulcan, and their leader Watts to undermine the Mach Storm team. At their disposal were a Nightwise, Mosasledge and Unelagia, respectively.

After obtaining information from Dr. Pierce concerning quad-combining Zoids, the three formulated a plan to find a Leoblaze to create such a Fuzor. Despite the Savage Hammer supply of Leoblazes, only one Leoblaze was compatible: the one belonging to Matt of Mach Storm. Tricking Matt into giving them his Leoblaze's data under the pretense of using to help him in Zoid battles, the men attacked RD and Matt while the two were in battle. The Leoblaze was forced in to a fusion with the Unelagia, Mosasledge and Nightwise, forming the Matrix Dragon. After ejecting Matt, the Liger Zero Phoenix was easily beaten. A week later, after numerous failed attempts to recover the Leoblaze (Sandra had forged registration paper claiming the stolen Zoid was theirs to begin with), RD challenged Savage Hammer in a battle for it. Midway into the battle, the three turned on both teams, leaving the Buster Fuhrer and Liger Zero Phoenix fighting it. Despite the "combined" (Blake was also after RD) forces plus the plan of Mach Storm, the Matrix Dragon emerged victorious. Immediately after, the Energy Liger revealed itself and destroyed the Buster Fuhrer and Matrix Dragon. Vulcan, Miguel and Watts were subsequently fired from Savage Hammer.
