Tony Stark

 Early Life: 

Tony Stark was born a few years before the conduit big bang. He was a child genius and became very inventive like his father, Howard Stark. After the big bang though, Tony was even smarter then before. He was able to make robotic designs that his father even dreamed of. H.Y.D.R.A. became very interested in Stark Industries' robotics and hired them to build weapons for H.Y.D.R.A. and their soliders. For years Howard Stark never revealed to Magnus who was really making the robotics and weapons until Captain Sullivan came to check on Stark's progress on a new missile and saw Tony working on it. Howard was arrested and Tony was forced to create for them. For the next five years Tony worked until he learned his father had been killed by Captain Sullivan. Tony ran from Magnusaur to Nessa to hide but was hit by a landmine that was filled with shrapnel that pierced his heart. He was captured by H.Y.D.R.A. who had put in his chest a magnetic chest plate which keeps his the shrapnel from killing him. The only problem it needs to be recharged everyday otherwise it'll kill him, also he's being poisoned by the magnetic chesplate and needs medication so it doesn't die out. So Tony listens to Magnus and continues to make weapons for them as long as he gets the medication and recharges he needs to live. Tony fed up of helping H.Y.D.R.A. makes his own magnetic chestplate and replaces it with his own so he can recharge it himself. Although Tony hopes for the day when the Underground comes and can help him get the antidote to his sickness and then go free from Magnus' control. He's so prepared for that, that he builds the strongest robotic suit he's ever made which is ready for him to use if H.Y.D.R.A. ever attacks.

 The Original Forgotten Avenger: 

Tony was shocked to hear his stations on Vestoria were destroyed by the Underground. He began to fear for his life thinking that the Underground who try to kill him for building weapons and robots for H.Y.D.R.A. so he finishes his robotic suit names himself Iron Man while in the suit. When Thalia, Jason, Aster and Wolverine appeared in Stark Tower, Tony thought that they would try to kill him so he put on his Iron Man suit and was the first to attack. Iron Man seemed to over power the four Undergrounders until Thalia used a metal coil choking Iron Man and electrocuting him and knocking him out. When Tony woke up he explained why he was working for H.Y.D.R.A. and building things for them. Thalia agrees to help Tony get the antidote in exchange for him to join the Underground. Tony agrees and brings them to an android center where they're about to activate.
