At Avengers' Tower, New Metropolis City...

Ultron Sigma: *voiceover* "Thanos is trapped, the tower unguarded... Send out the Parademons. It is time we finish him."

While the separate Teams were off finding the remaining Stones, Iron Man and Spencer were hanging back at Avengers Tower with Hawkeye, Green Arrow, Superman, The Flash, Raiden and Kabal that didn't get sent away.

Iron Man: "Remind me again why we're doing this?"

Dr. Light: *on the force field* "The Infinity Stones are too powerful for mortals to wield. A device must be constructed to harness them."

Iron Man: "Rhetorical question, Doc, but thank you. *to Spencer* Spencer, can you pass me that coupling there?"

Spencer: "Sure."

Spencer uses his bionic arm to stretch to grab the coupling for Tony and gave it to him as he caught it.

Iron Man: "You know, I could whip you up a replacement -- something a little sporty, little less "last place in the high school science fair"?"

Spencer: "Yeah! I'm good, thanks."

Iron Man: "Kind of attached to it, huh?"

Hawkeye: *on communicator* "Hawkeye to Stark.. We've got movement, seven klicks out..."

Outside, on top of the tower, Hawkeye and Green Arrow are seen spotting an army of Parademons approaching as the archers shoots their arrows at them.

Green Arrow: "Parademons, closing fast. It's Dark Khan. He's coming here."

Dr. Light: "Dr. Light: Charging shield. 60 seconds to full power."

Hawkeye: *see's couple of Parademons made it inside* "Got a couple headed your way!"

Back in the tower, the demons arrives as Iron Man and Spencer spots them.

Spencer: "Stark! We've got unwanted company!"

Iron Man: "Flash!"

The Flash: "On it."

The Flash then uses his Super Speed to punch two Parademons back and forth before performing a Teleport Uppercut on the last Parademon as the demon is down and the shield is activated.

Dr. Light: "Shield activated."

Iron Man: "Good job, Barton and Oliver. Take a break."

Hawkeye/Green Arrow: "Acknowledged."

Dr. Light: "Shield holding at 80 percent. At this rate, it will be breached within minutes."

Iron Man: "Great observation, Doc. Does anyone have something useful to share?"

Dr. Light: "Shield at 60 percent."

Spencer: "Stark. We're on our own here. We need Thanos -- we've gotta let him free."

Iron Man: "Uh, what's that word I'm searching for... No?"

The Flash: "Yeah. What if he betray us?"

Dr. Light: "Shield at 40 percent."

Thanos: *evilly chuckles*

Iron Man: "Something funny, Grimace?"

Thanos: "Tony Stark, Barry Allen, and Dr. Light. Three warmongers, fighting for peace, yet responsible for so much horror. Are your hands any cleaner than mine? *crosses his arms* Your shield will not save you. Release me."

Dr. Light: "Danger shield at twenty --"

A glass break was heard as the Parademons arrives.

Iron Man: "Guys, pizza's here."

Stark and Spencer shot the drones down before Dark Khan arrived.

Dark Khan: "Thanos! We see you'd traded one prison for another. Will you not bow to your new god?"

Thanos: "Ultron Sigma is no god -- he is a fool. He wield the greatest power in all creation -- yet he wear them like trinkets, and use them like a child."

Dark Khan: *approaches Thanos* "You have served your purpose. The remaining four Infinity Stones will soon be ours. How does it feel to know such power --"

Superman and Raiden arrives behind Dark Khan and Kabal begins to cancel the force field to let Thanos free. Superman fires his Laser Eyes while Raiden fires his Bolt of Lightning at Dark Khan as he yells in pain before performing a shockwave to push Superman and Raiden back and him to fall back as the force field has canceled out.

Green Arrow: "He's all yours, big guy."

Thanos: "As it should be."

Thanos then ferociously charging at Dark Khan, punching him backwards as Dark Khan blocks it in ease.

Dark Khan: "Did you forget, Titan? Our Kombat Rage are ours to command."

Thanos: *revealing his a Kombat Rage in his eyes* "Your Kombat Rage will not save you this time."

Thanos and Dark Khan begins to fight as Dark Khan fires his Omega Beams while Thanos fires his Final Judgement as their attacks collided before Thanos' attack hits Dark Khan defense. Thanos then begins to perform his final attack, Cosmic Fall as he uses his bare punches and send Dark Khan to the air, then uses his cosmic power to strike him while he jumps in mid-air as a finishing move. Thanos landed as the Kombat Rage faded and Dark Khan barely stands up and growls in pain.

Dark Khan: "W-We-I-I-I-iiiiiii -- Y-You hurt me. Y-You hurt us. That HURT. We must retreat, and repair. In time... You will all come to us."

Dark Khan warped out back to Xgard to repair.

Kabal: "Damn! He got away!"

Superman: "Well, at least it gives us time to figured out how to take him and Ultron Sigma down. But for that to happen, we need the four remaining stones."

Raiden: "Yes. We just need to hope everyone else is able to do their part. The Elder Gods has informed me that Shinnok has been resurrected by Quan Chi himself by using his Amulet. So he must be heading this way to attack Earthrealm."

Iron Man: "Now, that's bad news. Looks like we need to deal with Quan Chi first before we go forward to stopping Ultron Sigma and Dark Khan."

Hawkeye: "Right."

Green Arrow: "This is getting crazy as we know it."

The Flash: "But, we've faced crazy things before. I'm sure we can do this without getting ourselves killed."

Spencer: "Let's just hope for a miracle."
