1. Bart Allen
2. Booster Gold (wherever those two are right now)
3. Donna Troy
4. Big Wally West
5. Blue Beetle (both Jaime and Ted, you can't force me to pick one over the other)
6. Midnighter
7. Nightwing
8. Roy Harper (who would likely be higher on the list if someone brought back his daughter)
9. Tim Drake
10. Ralph Dibny
Honorable mentions: Jon Kent (Superboy) and Little Wally West (Kid Flash) are starting to grow on me.
It was harder than I thought to pick 10 characters. I think I'm more a fan of team dynamics than single characters, tbh.
