The Alien Queen was a giant Alien Snapper that Ratchet encountered at the Blarg Tactical Station in the original Ratchet & Clank. It was the first boss in the Ratchet & Clank franchise. It would summon smaller Alien Snappers, as well as Alien Swarmers to aid her. When dealing with the extra enemies, the Alien Queen would back away from Ratchet until they were all defeated.

The beast would attack Ratchet with a lunge. He defeated the beast so that he could press on and obtain the Grind Boots from Fred the scientist.

It is unknown exactly why it was referred to as "Queen." It may most likely be because of its large size. While it was most certainly not the Queen of all Aliens, it was likely that the creature was the Queen of all the mutants coming from Orxon.
