Velguarder

Velguarder (ベルガーダー) is Sigma's pet dog/wolf. X faces 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.

Trivia

 * In Mega Man X, if the Hadouken is used just at the exact moment you regain control of X after the intro sequence, it will jump right in front of X as you shoot him point-blank, hitting him and ending the battle.
 * Velguarder also has a short appearance in the opening scene of Mega Man X5.
