Metropolis’ Brainiac invasion may seem like an ordinary event that citizens find themselves dealing with in Suicide Squad: Kill the Justice League’s DC universe, but it is particularly random when considering that this is occurring in the established Arkhamverse. It is fully likely that events such as this were happening all the time outside of Gotham City, but fans were none the wiser due to the Batman games being isolated incidents. Because of that, Rocksteady could still offer a lot of closure for characters who have been seemingly abandoned since.
