The daughter of Pinky and the Brain named Lucky is not mine, but I just found this art in Deviantart. But I really like this girl and want to add her to Pinky and the Brain's family tree. If you don't mind of course. :3
Something I love about Pinky and Brain’s relationship in the show is that it is unlike other villain/dumb sidekick tropes. Most villains treat their sidekicks like shit and care very little about them but Brain ACTUALLY cares for Pinky. Every time Pinky is in trouble, Brain goes to save him. In the beginning of the episode To Russia With Lab Mice when Brain realizes they are about to crash, he grabs Pinky and gets him out of there. That is just one of the many, many examples of Brain caring for Pinky and it really makes them unique in that trope.
