I wanted to see if others have viewed this the same way aswell. Every time I have seen mumm-ra do his supposed power-up where he invokes the ancient spirits of evil and gets more powerful lately, I’d actually start to cringe a bit because this invariably means he’ll actually make himself weaker instead of stronger. I never had this in the OS, but here he 100% of the time does fine, until he transforms then he fails. In the finale it is even worse, he does yet another “power-up” which makes him EVEN WEAKER.
If only you had always stayed in decayed mummy form you would have conquered third earth already!
