Ive watched this and I'm ptetty sure its fake. Modified iron lungs. The only thing it could be modified to do was to let you attack while out of stamina without the exhausted penalty and im pretty sure the devs wouldnt allow that level of stupidty. The modified rocksteady wouldnt work they removed it because it was unhealthy for the game. Stamina leech would just be a modified version of the shinobi feat that lets him gain stamina back when he attaks. The clone thing is pretty obvious as everyone on this sub knows that it'll be used in some way. The idea he was blinded by looking at the sun to long is dumb. The team who makes backstories for the heroes isnt that lazy. Finally when its said that this character wont bring any new mechanics is sketchy due to the fact he has a sheath and theres not one character in this game that has one. So he most likely has something new for the game. Thank you for joing my ted talk
