I guess the official name for the Lombax is Alister Azimuth. IGN has an interview with designer Brian Allgeier:
IGN: What can you tell us about Ratchet and Clank's new buddy, Azimuth?
Brian Allgeier: General Alister Azimuth was a once-revered Lombax leader, and a friend of Ratchet's father. R&C fans will recall that in Ratchet & Clank Future: Tools of Destruction, Ratchet battled Tachyon in the "Court of Azimuth". This was architected by Azimuth, and one of our first hints of his existence.
