Here's some odd facts about him:
- He's the only current Robin to have been asked to take on the role. New 52 has Alfred asking along with Bruce.
- Counting pre-Crisis he's the sidekick that's had the most parents. Try guessing how many if you don't already know.
- I don't think they ever said how tall future Damian was/is or the Heretic (although he had his genetics messed with) but Jason is taller than Dick and Tim. Two inches shorter than Bruce.
- Although his current rebirth is still sketchy pre-52 Jason dug his way out of his coffin with nothing but a belt buckle.
