Rimmicu was a protoss of the Templar Caste who served alongside Iaalu.
During the Great War, Rimmicu had lost his entire unit to a pack of zerglings, as well as all of his limbs. Through his will, he used the remains of his muscles to fly a hover-platform modified from interceptor parts. He then broke from his orders, and started hunting down every zergling he could find, before finally being killed by a zerg queen.
The last words he said to Iaalu, "Uhn dara ma'nakai," ("Our duty is unending" in Khalani) would stay with him through his service, and drive Iaalu to push through immense pain.
