7. Doctor Mid-Nite

While I do like Charles McNider, It's Pieter Cross who holds the title of "my favorite Doctor Mid-Nite".

As a doctor running a free clinic, Pieter ran afoul of some drug dealers selling A39, which was a new drug and sadly not an indie production house distributing a bunch of cool movies (That was a joke for my film nerd pals). Said drug dealers engineered a car accident to get rid of Cross, who survived, blind, but with the ability to see in infrared and ultrasonic spectra. He decided to take up a position as crime-fighting super doctor for the capes and tights set.

He also has an owl. Because if you thought he couldn't get any better, you were dead wrong.

The Doc is the dude you hit up if you need an autopsy performed or need a superintelligent virus extracted from your brain. Plus he's a master of youth outreach, so points for that!
