Velguarder

Velguarder is Sigma's pet wolf-like Reploid in the first Mega Man X game. He acts as a replacement for Treble, Bass' pet wolf-like dog.

Strategy
In all games where he appeared, Velguarder will run and jump around the room to make the fight more difficult for Mega Man X. He'll also shoot fire and projectiles from his mouth, making the fight tougher and then he'll repeat again.

In Mega Man Xtreme 2, Velguarder shoots sticky orbs in Extreme only.

Trivia

 * Velguarder makes a cameo in Mega Man X Collection.
