Appearance:
BRIEF Bio: The twins were first discovered at an orphanage as babies and soon after a man and his wife adopted them while they were still very young. Ten years into the Gotham family's lives had the twins losing the woman they'd called mother in a car wreck during a time when the Jokerz gang was really making a name for itself. Over the course of the next several years, their grieving father made it known he didn't care for the criminals in Gotham or the 'heroes' who hide behind masks trying to battle them. However several months ago, the twins' father Greg Winston, went out to pick up dinner and never returned home. It more than likely had something to do with him witnessing the kids using their new metahuman abilities days earlier. After only a few weeks the kids were evicted from the apartment. They were close enough to eighteen that nobody really cared if they were homeless or not.

That's when Matt McGinnis and his mother saw the twins defending themselves against a handful of Jokerz. Matt knew that those kids had nothing to lose and everything to gain. Days later the younger brother of Batman found the teens picking up an internet signal outside of a Pizza Play resteraunt on electronic devices they hadn't yet pawned. A couple bags full of clothes and a few belongings were all they had to their names. Matt explained how he was the new Robin and was forming his own team of Titans, and the twins quickly agreed to join. Living in an abanndonned 19th century arcade, they agreed to let it also serve as the base of operations for this new team who's first mission was to knock Batman himself down a peg. 

Two weeks later when Matt McGinniss was killed the boys were back to square one. That was until Batman returned and said he was putting the team back together. He told the twins Matt was his brother, and how he had to do it to honor him. Both understood and helped Terry construct a bunker HQ under the old arcade. The twins moved downstairs into the HQ where one or two other teammates could also have a room there. Over the last four weeks, the eight times Batman had showed up for training were the highlights of the month. Each member of the team got new suits and in memory of Matt a statue was put up towards the entrance of Robin.

Notes: * After the first arc the boys will get tired of being called Wonder Twins and stop dressing alike. Their powers will also begin to evolve [like Beast Boy to Animal Man and Poison Ivy to Swamp Thing]. 

* J and Z no longer attend school. They were both however juniors in high school when they dropped out, with Z accelling in academics and J being into more physical sports at Hamilton High. Matt McGinnis was a sophomore before bein killed and Terry/Batman is currently in college. 

* Only the members of the team who saw Matt more frequently at school [possibly any who were in his grade or in several classes with him] knew his identity but they were still unaware he had an older brother who was Batman. The twins now know his identity as well as Batman's since Terry opened up to them about Robin being his younger brother. His secret is safe with the twins.

* One of the twins will have a day job. 

* Bruce Wayne is funding the team but also on the verge of dying. With Paxton Powers in jail the ownership of Wayne/Powers falls on the stockholders and Terry McGinnis' shoulders, as Bruce Wayne gave Terry his remaining shares of the company.
