I notice that Batgirl (Barbara Gordon) and Batgirl (Stephanie Brown) cape is either black, yellow, or purple on the inside and black on the outside while Batgirl (Cassandra Cain) is either black or yellow. If you were do come up with a modified Batgirl (Helena Bertinelli/Wayne) Maybe something like Barbara Gordon's but a purple suit or purple boots and gloves with everything else the same as Barbara's suit here. Maybe a Yellow or purple suit with black gloves and boots, and if yellow either purple or black bat symbol and belt.
You should do one of Batgirl (Helena Wayne) She's a counter Earth version of Helena Bertinelli were Bruce is her father and Selina Kyle (Catwoman) is her mother. I came up with an alternate Batman Beyond, were the suit is like Terry's but has a yellow bat symbol like the Batgirl here and he suit has yellow arms and a black belt. You've probably seen the Green Lantern Movie with Ryan Reynolds, there's a part where this guy infected by the yellow energy like the yellow energy in the Yellow Lantern's power ring throws this woman through a window, that lady is Amanda Walker, she is a government agent that deals with superheroes in case they go Rouge, She is also the woman who creates Terry McGinnis, She steals DNA from Batman (Bruce) cause "The world needs a Batman" planting the DNA into Mrs. McGinnis, I don't remember how. Well, in this alternate Earth Amanda Walker is killed when she is thrown into the glass, so no Terry, But Black Canary and Green Arrow have a son, he becomes the new Batman, cause Batman (Bruce) has alway been like a grandfather to him. This new Batman learned how to control his sonic cries from his mother, how to shoot a bow from his father, and his ninja skills from Bruce.
Why did this Batman and Robin pairing ever happen? It's dark and dreary Sr. and dark and dreary Jr.! It just... wouldn't work. Bruce needs a lighter personality to balance him out. And so does Damian. *cough cough Dick cough*
That's precisely why I loved those two together - besides, it's father and son . There was a moment in an issue of Batman & Robin when Damian was trying to tell Bruce that he appreciated him, and Bruce replied with "huh, what? I wasn't listening" - hahaha poor Damian. But I promise once you see the animated "Son of Batman" feature, you'll love this pairing. Not that I've seen it, but I have faith it'll be a good one!
I just realized that the new 52 just brought back what happened after dick became Nightwing with Damian standing in for Jason and even his death and we got both Nightwing on his own his own and with the teen titans with red robin
