This is an idea so please don’t criticize too hard on me here.
This hero’s full name is Terrariss Verith. He is from Amsterdam. He is 35 years old and was 17 when the Omnic war started. He saw the carnage and felt he had to take a stand and protecting some people from the invasion. He spent most of his long years after the war to build himself. This has lead him to add to himself making him stronger and reach his goal to help again when overwatch returns.
His passive is True Vitality. This hero gains bonus healing from everything and reduced cc duration.
His shift is Brute rush. This ability gives him increased movement speed and damage reduction while active.
His E is called: Great Taunt. This ability gives him bonus armor and all enemies in an area around him must attack him or take damage.
His Ultimate is called Great Cataclysm. This causes him to go into a stance and any enemy who attacks him deals increased damage to him but he can not die. After a period of time he will then attack back dealing massive damage equal to the damage he takes to an area. If he is hit with another Ultimate ability he will then take all the damage from it regardless if it also hits an ally or not.
This character is built to be a tank but to him being a tank is becoming a tank.
