Thought exercise

Sometimes I like to take a particular superhero and imagine some kind of random skill or ability or talent that character might have, which has no support what-so-ever in the actual comic book merely because the idea amuses me.

For example, I think Guy Gardner can bake a mean quiche. He doesn't advertize this fact, but if you ever need to save the world with a baked egg dish, he's your man.

I also think Damian Wayne secretly knits. Alfred taught him. He's making a hat.

Can you think of any similar ones? :-)
