(Washington DC, USA)

When Superman, Batman, and Wonder Woman arrived at the White House, the place was not even guarded. Superman used his x ray vision on the place and found only one person inside. He noticed that the person is walking outside the building; from the looks of things, it was Lex Luthor.

Wonder Woman: Luthor? What are you doing here?

Batman: Thats not Luthor; its just his body with The Brain using it.

Brain: Correct. This is to be expected from the World's greatest detective.

Superman: What happened to the real Lex?

Brain: I used his technical know-how to build the MASE suit's primary functions and experiment on the captured heroes and villains I acquired. Once he was finished, I erased him and the others that refused to work for me anymore. The rest that agreed to my proposal and the ones that are still allied with me have been moved. Only I am here.

Wonder Woman: So all this just so you could make a weaponized suit to conquer the worlds under your command.

Brain: Yes! And I know have the power to do so. And one other thing: Thank you(Batman and Superman) for making sure I could get kryptonian blood for myself.

The fighting started with the Brain attacking first. Superman managed to get in front of him first and stop his attack briefly, but Brain bounced back. Batman then threw his batarangs that doubled as explosives. They had no effect, but Wonder Woman used the cover as a way to attack him. She used her sword to attack him, but he managed to stop the attack and break her sword. Superman used his heat vision on the suit to heat it up, but it did not work since the suit adapted to the the heat. However, Batman used a special EMP on the suit and shut down the suit; it was designed to shut down the MASE suits.

Brain: Well played Batman.

Batman: Once the MASE suits were introduced, I made countermeasures for them in the event they got out of control.

Brain: You may have shut down my suit, but…..(flying in the sky) I have Kryptonian powers thanks to the blood Deathstroke collected for me.

Superman: You may have my powers, but that doesn't mean you own them.

Brain tried to hit them with heat vision, but they managed to avoid it. Wonder Woman then used her lasso to restrain him; this would give Batman and Superman time to attack. However, Brain escaped the lasso and went over to attack Wonder Women; he then grabbed her arm and twisted it. Superman then intervened with his assault and took Brain into the air where they continued to fight. They were both evenly matched in their fight since they both had kryptonian powers. Superman then used his laser vision on him, but the Brain counteracted it. They kept punching each other until Brain manged to land Superman on the ground. Batman attacked Brain from he got up close to him, Brain grabbed Batman and used all his power to hit him in his spine. Once he was hit in the spine, Batman could not move. However, Batman had left a canister near the Brain. Once the canister opened, it revealed green Kryptonite and it weakened. Then Batman used something that he never thought he would have to use: Gold Kryptonite(which takes away Kryptonian Powers).

Brain: Where did you get that?

Superman: I gave it to him when I discovered it a long time ago on one of my space adventures. It takes away kryptonian powers permanently.

Wonder Woman: Its over!

Brain: You may have defeated me, but that does not mean…(his chest and the suit he was wearing was starting to tick; it had 3) I am finished.

Batman: What have you done?

Brain: In the event I could not take over this planet, I plan to destroy bomb I placed in my body and the suit are powerful enough to destroy this entire planet. It is made of a powerful material that are enough to destroy organic life of any kind. Thanks to my "friend".

Batman: Who gave it to you?

Brain: You will find out 12 years from now, if one of you can stop this thing.

(Superman grabs the suit and the Brain)

Wonder Woman: What are you doing?

Superman: Only I can do this.

Batman: You know this is a one way trip?

Superman: I know! Tell Lois goodbye for me.

Superman went into the air with both Brain and his suit. He went far into space as far away from earth as possible. Once he was far enough, the suit and the Brain exploded with him and the Brain with it.

Once things were cleaned up, a team went to search for Superman in case he was alive. Unfortunately, they found his body completely burned and parts of his bones being shown. There was no doubt that the Man of Steel is no longer with us.
