I was completely unaware of this character until I read the Grayson volumes of comics back in 2017. I always loved Nightwing as a character, and this was a sort of new phase of Nightwing's career as an Agent 37. He works for Helena Bertinelli's (Huntress) spy group Spyral, and he encounters Midnighter keeping an eye on Spyral. They initially clash, and later Grayson convinces Midnighter to join him in his fight against a cult group, the Fist of Cain.
But Midnighters story is more or less that of a normal human bioengineered and enhanced with neural implants to give him abilities. He was initially part of a covert group, then transitioned to The Authority, which watches over world governments. He hasn't directly dealt with Batman, but he has with many of the Batfamily. He is usually depicted as a pretty violent, brutal fighter with superhuman speed, resilience, pain control, and strength. He is equipped with a neural implant that allows him to process every possible combat outcome. Basically, if there's a possibility he can win, he will!
The figure is pretty good, and this simple design and colour palette is exactly McFarlane's wheelhouse. I love that he comes with punching hands, but where were those with EVERY Batman figure?!? I also like the batons, but I don't remember him fighting with these; he was just using a bo staff.
