"Attention people of Earth," Brainiac says over a speaker.
"This is Brainiac. Your planet is now mine. Surrender to me and I will spare you all. Failure to do will result in your elimination."
"Like hell I am!" Superman yells.
"I see you have a robot ally next to you Superman. Big mistake!" Brainiac booms.
Suddenly the Iron Giant transforms. His eyes turn to green and his body becomes bigger.
"What is happening to him?"
"Brainiac has the ability to possess any form of technology. That includes him."
"That is correct Superman," Brainiac says through the Iron Giant.
"Now your mechanical friend is under my control."
The Brainiac-Giant turns his arm into a gun and starts blasting buildings and people. It tries to shoot Lex Luthor but Superman saves him.
"No buddy. Fight it!" Hogarth says.
He looks at Superman for answers.
"How can we stop him without destroying the Giant?"
Superman tries to think of a solution. After a couple of minutes, he finally has an idea.
"I have a plan. We are going to use you to get to the Giant."
Hogarth looks at the rampaging robot and then back at Superman.
"That is your brilliant plan?!" Hogarth yells bewildered.
"It's the only one I could come up with," Superman replies.
"It's not the only option," Emil Hamilton says from a STAR Labs Jet.
He throws down a mechanical cap.
"What is this?" Hogarth asks.
"It's a mind blocker. If my calculations are correct then it should force Brainiac's mind to leave the Iron Giant's body."
"Thanks, Doc."
"I am not Doc Brown Hogarth. You can just call me Emil Hamilton."
"Alright. I am going in."
"I will distract the Giant," Superman says.
Superman flies over to the Giant. The Giant starts swinging its fists at Superman. While the Giant is distracted, Hogarth sneaks up behind the Giant.
"Hey Brainy or whatever you call yourself!"
Brainiac-Giant looks at Hogarth. He laughs.
"You and what army?" Brainiac says.
Superman lifts Hogarth into the air to the Giant's head.
"Now Hogarth!"
Hogarth throws the mind blocker at the Giant's head.
"What is that?? Argh!"
The Giant struggles to free himself.
"Come on! I know you can do it!"
The Giant looks at Hogarth.
"Ho-Garth."
Brainiac's mind leaves the Giant's body.
"Noooo!" Brainiac yells.
"Good to have you back buddy," Hogarth says.
