The MS-17 Galbaldy α or Galbaldy Alpha is one of Zeon's last Mobile Suit. Intended to be a successor of the YMS-15 Gyan, but due to the higher ranks rejecting the Gyan for the more versatile MS-14A Gelgoog. Refitting was needed.
The Galbaldy Alpha is thus-far unique in this game, as being the only mobile suit with a Level 2 Combat Avoidance. Which grants this suit the ability to perform a dodgeroll, twice. The first dodge reduces your thrusters to about 70%, After which you can either boost away, dodge again, or wait a bit to avoid overheating.
