User blog comment:Numnum22/The Simpsons characters with similarities to other villains: Cecil Terwilliger/@comment-31330278-20190209235039

Here are some: Simon Gruber (loyal brother who'll kill anyone who'll hurt his brother Hans), Debbie Loomis (loyal to family, but a sociopath to everyone else) and The Big one from Jurassic Park (cruel, insane, avenged her siblings/soldier despite killing anyone who opposed her, including her other siblings).
