"Well, usually he looks all ancient and creepy like you'd think a mummy would," Kit said, briefly hunching her shoulders and curling her fingers like claws to demonstrate. "But then he goes 'Ancient Spirits of Evil, transform this decayed form into Mumm-Ra, the Ever Living!' Then he grows like ten feet tall with big muscles and bat wings! And now that he has the Tech Stone, he can turn into an even bigger, tougher form that's all covered in armor and stuff!"

Kit gestured at appropriate intervals to indicate Mumm-Ra's increased size in his Ever Living and armored forms before settling down. "But even when he's just old and creepy, you gotta watch out for his magic. He's really powerful."
