Velguarder

Velguarder (ベルガーダー) is Sigma's pet dog/wolf. X will face him before facing Sigma himself in Mega Man X. Velguarder's weakness is Shotgun Ice (provided that the Hadouken wasn't acquired earlier).

In Mega Man Xtreme 2, Velguarder is the first boss of the final stages.

In Mega Man X: Command Mission, the Velguarder is a mass-produced robot called Wild Dog. Wild Dogs are common enemies that appear in the Vanallia Desert.
