Here's my version of Robin:
Name- Dick Grayson, the original, the one and only.
Age- Somewhere between ages 14 and 17
Origin- Same as the comics,but here's the twist: Bruce didn't attend the circus, thus Dick feels alone and joins a street gang. He meets Bruce, who comes to his defense when Dick is on the run from a rival gang. He lets Dick stay for the night at Wayne Manor. Just when Bruce is asleep, Dick discovers the Batcave by removing a bat from a grandfather clock. The next morning, Bruce takes him out of an juvenile services system when he finds out that it's abusive. Feeling neglected by Bruce, Dick sneaks out of the manor late at night to exact revenge on Tony Zucco. He takes down his men by using his acrobatic skills and streetfighting skills. Batman stops Dick from killing Zucco, telling him "you'll be back to square one". Dick said he wanted to make up for his actions, Bruce felt sympathic and offers him to be his "son", but not before revealing his identity to Dick.
EPILOGUE-
Dick is sitting at a chair at Wayne Manor;looking at a window
DICK(V.O.)
Come on, there's gotta be some inspiration.
Bruce walks into the room
BRUCE
Why are you looking at the window, Dick?
DICK
Trying to find some bats. You can't be Batboy without some inspiration.
BRUCE (laughs)
I doubt you'll find more bats out there than in the cave
DICK
So, no "Batboy"? Then, what will I be?
Just as he says this, a little red robin flew past the window
BRUCE
How about being a "robin"?
DICK
I don't know. That name would encourge bullies to beat me up.
BRUCE
But, being a robin won't so bad, you'll get your own set of wings.
DICK
Ok, fine. Besides I will be like Robin Hood, but I don't have to wear a dumb red hood.
BRUCE
Okay, Dick. You'll be Robin. Good night son.
DICK
Good night, dad.
Costume- Basically this costume, but without the cape:
Instead of an eyemask, Dick would wear hi-tech sunglasses (like the Green Arrow in Smallville.)
But the coolest thing about Robin's suit is that it's not just a costume. It's a "powered suit" that is form fitting and highly responsive (just like Terry's Batsuit in Batman Beyond). This suit conforms to the size and the physique of the wearer. It's very durable and it's resistant to heat,water,electricity,wind and vibrations.
This costume would give Robin the following:
-retractable wings under the arm to glide on
-Built-in cloaking device which renders him nearly invisible
-a two-way radio and surveillance system that allows Robin to keep in constant contact with Batman
-Enhanced ballistic protection
-Built-in rebreahter for underwater combat & exploration
-Dispensable R-shaped shurikens
-Grapple guns built into the forearms
-and some of Batman's gadgets and equipment
