Some things that have not been said yet...Remember how Miserix has owned pretty much everyone? Yes, he did lose to Teridax, who we know is pretty much hard to beat. But after being imprisoned for millennia, he has1. Absorbed Spiriah, a fellow Makuta.2. Absorbed Makuta of Stelt, also a fellow Makuta.3. Destroyed machinery in Core Processor, only to be defeated by Teridax, now with powers of Great Spirit.4. After being freed by Tren Krom in Lewa's body, he defeats him in the fight by SLAMMING HIM TO WALL! I know, not so good usage of Makuta's powers, but still cool.Alternate Teridax have also been not mentioned. DM Teridax isn't killed by Toa Empire. Kingdom Teridax was killed, but how strong would you be after being alone for 10,000 years? Melding Teridax managed killed several Takanuva, using his battle skills, not his powers, and only got slightly injured.Maybe using so much powers is diffifult? The DH Conjurer sunk comatose when he tried to copy the powers of a Makuta. So it could take a lot of concentration to master all of their powers, and not all of them might not have been interested in training.About the powers of Rahkshi: wild Rahkshi are not even close as powerful as the Rahkshi in BoM's armies. Nokama, a novice Toa, managed to subdue three of them in BA3.
