I always give myself writing exercises to pass the time at work. My longest running (20 years now) is creating the "perfect" Amalgam universe. My goal was to create 1000. Never did it because I'd always get hung up on something or distracted by another exercise, so I'm going to do it in public to get it out of my head. I'll post a few each day until I'm done.
1. Firestorm + Iron Man = Iron Forge, AKA Ronnie Stark
2. Martin Stein + Edwin Jarvis = Marvin Steinway
3. Dr. Fate + Sgt. Nick Fury = Sgt. Fate
4. Spectre + Sub-Mariner = Necromancer
5. Wonder Woman + Thor = Thunder Woman
6. Brother Power + Brother Voodoo = Voodoo Doll
More to come.
