Elmo on steroids? You could say that. Bimf is the muscle of the Range Patrol. His people, the Sanslorian, were victims of the Cartel's ruthlessness, and Bimf (with help from Beamer, as we will see in Range Patrol #4, "A Sanslorian's Tale") helped lead the last few hundred of his people to safety in Eastern lands. The Prycenes trained the Sanslorian in the art of war and set up a system in which the Sanslorian refugees were "loaned out" to various police organizations elsewhere on Hearthstone to help combat Cartel influences. Bimf ended up assigned to Nullabor's Range Patrol, and over the approximately eight revolutions he has been with her team has come to regard Sheila as an adopted daughter. (A joke goes around that no one goes on a date with Sheila unless Bimf chaperones...it's actually true.)
Like all Sanslorian, Bimf has what would be considered unusual biochemistry. He is capable of eating metal (and in fact, needs it to survive) or even rocks and minerals, and also doesn't need to sleep. This makes him a valuable asset to the Range Patrol as he can constantly be on guard.
All we have here are some pics of Bimf's fellow villagers. The second is the village elder S'Jayce. The first is Leiara, "She Who Speaks" for her village. They'll both appear in RP #4, and Leiara will appear in ST #3 as well as in the future Claw of Vengeance series.
