The Cyclitharans, a species known for their strength, bulk, and close resemblance to Human beings. These species, though strong, were a somewhat peace-seeking race that often didn't seek battle. Though strong and large, they abided more on the gentle side only when it came to getting what they needed.
Some speculated that the Cyclitharans could wipe out the Ethisians and Granians in one go without requiring assistance from any other species if they felt like it. However, the reason it remained a "speculation" was due to the aggressive mindset the Granians possessed, their battle tactics, and the sheer size and physical/military strength the Granians AND Ethisians possessed.
So in all honesty, the Cyclitharans wouldn't manage wiping out both races but they certainly could go toe-to-toe with them and escape with severe damages and casualties. In terms of strength across the Galaxy, they were the fourth strongest directly under the Parsians.
