Or morph them into one person.
Pelosi is cagey and smart in her own way. Cortez is dumb but malleable so she’s easily controlled by a 3rd party. Left on her own she would soon wither and die from lack of direction. Cortex will never be anything more than the sock puppet she is today. Plus her and the rest of her goober squad are plain old fashioned evil with zero redeemable features or assets.
You may be on to something. Perhaps she is the same person, and she’s a sci fi type shape shifter?
