4. Frankenstein
Yes, this is the DCU one whose name ACTUALLY IS Frankenstein. So please take your "Frankenstein is the name of the doctor" comments and bring them back to 1983 when they were original.
So Frankenstein is the perfect, seemingly immortal, soldier to act as the team's resident bruiser. Grumpy, grouchy, and prone to cut things he dislikes in half, Frank would easily be the best depiction of the classic monster we've seen onscreen in a long time.
A world-weary grumpus, Frankenstein feels perfectly suited to a team of sky's-the-limit magic users. Everybody needs someone around to ground them, and if that someone is a hundreds of years old monster with a penchant for stabbing, that sure would make for a great movie.
Also, throwing a creature brought to life by science into a team of magicians is a great balancer for some of the weirder stuff this movie will need to show.
