Pre-Crisis

Before the Crisis on Infinite Earths changed DCU, there were two twins named Wayne and Walt trigger. The story takes place in the old west.

They appeared in an issue of All Star Squadron and was there during the Crisis on Infinite Earth's.

After the Crisis

After the First Crisis, two people Tad and Tom trigger who are unaware they are twins and haven't met yet, decides to rob a bank. They both see each other's faces and are surprised that they lookalike. They decide to team up and finish the robbery themselves. They later begin to work for a local number's runner after he talks them into working for him. The duo then begins to kill the man's enemies.

Their next appearance was in Gotham City which spelled bad luck for them because Azrael was filling in for Batman after Bane broke his back and had upgraded the batsuit to shoot sharpened bat blades and mounted the gloves with razor sharp claws. The twins started by robbing a train loaded with money but Az/bat's arrives and stops them.

Later, a blonde female criminal rescues them and claims that she is there sister and needs their help. This turns out to be a ruse so that she could pull a heist at a wild west Gotham city tourist attraction. Robin and the new Pow-wow Smith and Nighthawk defeats them.
