On Young Justice, Wally is making his first foray out there into hero-dom on his own, having been a sidekick for a while. Despite his joking nature, he wanted to be taken seriously for what he could do.
What I love about Wally is that humor. A lot of superhero stories are dark, about tortured souls and ugly temptations. You see a lot of the theme that power corrupts, or that massive self control and denial is the only way to deal with superpowers. But Wally is full of joy and fun. He delights in his own skill and in making a difference in the world.
And, while he loves to flirt, I don't know what he would do if anyone took him up on it, besides stammer and blush. He's adorable.
