A new hero

You decided to add your self as a new hero to the world itself. You will give yourself a non-hero life as well and with your powers you can easily be a hero at the same time as you live the non-hero life. The non-hero life will be a CEO of a company which you set up to be a fairly well off one.

Now for your Hero powers and name. You decided make yourself akin to Iron Man and made yourself a suit of high tech armor with your right arm being replaced with a cybernetic one. The suit and arm are powered by a Arc reactor and it has all the tricks of the Iron Man suit but non of the weapons being lethal be you do have the ability to go lethal in the event you are able to kill one of the more dangerous criminals like the Joker, no way in hell you are letting him live if you are able to deal with him permanently. You set up a base hidden in the Rockies unable to be found unless a signal was sent from the base to the Watchtower. You set up defenses as well and scanners linked to a data base to know who are the ones in the base and for the defenses to know to go lethal or non-lethal on the invaders unless you allow them to be there.

You upped the ages of the younger superheros like the Titans and Young Justice to 17 or 18 years out and put yourself at the age of 18 as well while the other you would be 21 years old and with the same mind set of Tony Stark without the personality he had with the right arm being human and your looks slightly different from one another.

You set up both of your new lives files into the government servers and then made both form as the DC earth came to life. You drop yourself randomly in location and time. You appear near Jump city and decide to go for a fly to get used to the armor. You were going to do a fly by of the city when suddenly a explosion happening in the city with more following. You turn and fly in and found the Titans fighting....
