RAINBOW BRIDGE: ASGARD

The bifrost opened up on the Rainbow Bridge, the three teams emerged from the Bifrost. They were met with swarms and swarms of robots, thousands and thousands of them. Superman, Sonic and Cap were at the front of the large group, leading their teams. With a battle cry from Cap, the heroes then charged at the swarm of robots, the robots charged back. When the two charging factions finally met each other the battle finally commenced. Sonic and Shadow spin dashed through a horde of robots, when Shadow untucked from his spin dash, he launched himself into the air and used a Chaos Spear, destroying the horde of robots, while Sonic used his Sonic Wind attack to tear apart the robots. Silver used his psychokinesis to lift the robots into the air so Superman can use his Heat Vision to destroy the robots. Then he flew right through a group of robots, destroying them. Omega and Iron Man were using their weapons that were at their disposal to decimate the robots. Black Widow, Rouge and Batman were also fighting the robots as well. Black Widow was shooting the robots, Batman was using his gadgets and Batarangs to combat the robots and Rouge was using her spin kick to tear the robots to pieces. Thor and Shazam used their lightning abilities to obliterate the enemy forces, while Wonder Woman and Amy were bashing the robots heads in. Green Lantern used his ring to make a construct, specifically a giant train which in turn, rammed the robots to pieces. Cyborg and Tails used their arm cannons to destroy the robots. Hulk and Superman both smashed the ground causing a shockwave that knocked down the robots. Flash and Sonic then slowed down time while the fight was raging on, they ran over to a bunch of robot forces and destroyed them. Flash literally dismantled a few of them, while Sonic spin dashed them to pieces. Time then resumed to normal and just as that happened Cap, Superman and Sonic then took charge and charged towards the citadel. Teams Avengers and Justice League went towards the citadel while Team Freedom Fighters went towards the Watchtower Teleportation Bridge to take back the Watchtower.

WATCHTOWER TELEPORTATION BRIDGE: ASGARD

As Team Freedom Fighters headed towards the Teleporter, they encountered some enemy forces along the way, they destroyed them with ease but that encounter caused them to stay vigilant. They entered the room where the teleporter was located, only to find that the teleporter was guarded by Neo Metal Sonic. Sonic smirked at his robotic counterpart as they both charged at each other with extreme speeds. While Sonic fought Neo the rest of the team fought off the robots that were near the portal. Sally and Tails tried to run to the computer console while Sonic and Neo were literally bouncing around the room, they were almost there but after he knocked Sonic down, Neo intercepted them.

NEO: AW, YOU ALMOST MADE IT THIS TIME.

Neo then smacked them both away from the console with his extreme strength.

NEO: I'M DISAPPOINTED, TRULY. YOU'RE DEFEATED, AND I DIDN'T EVEN NEED TO USE MY FINAL FORM.

SHADOW: CHAOS SPEAR!

Shadow then stabbed Neo with a Chaos Spear right in the chest, then he kicked the twisted robot to the teleport pad. Tails then did his magic on the computer and activated the portal, on the screen it said "Destination: Ice Cap Zone". Before Neo had time to react, Tails activated the teleporter and sent Neo to the Ice Cap Zone.

SONIC: Nice thinking guys. Come on, let's get to the Watchtower.

They stepped on the portal and Tails activated it and quickly joined them as they were sent to the Watchtower.

WATCHTOWER

Team Freedom Fighters had arrived on the Watchtower in the teleportation room, only to be greeted by Dr. Eggman in his Death Egg Robot surrounded by a group of Badniks.

EGGMAN: WELL, WELL, WELL. IF IT ISN'T THE FREEDOM FIGHTERS, I KNEW YOU ALL WOULD COME UP HERE AND TRY TO SPOIL MY FUN. BUT HONESTLY, I THOUGHT YOU WOULD HAVE COME SOONER. BUT IT DOESN'T MATTER NOW, BECAUSE NONE OF YOU ARE LEAVING HERE ALIVE! HO HO HO HO HO!

The Freedom Fighters got into a battle stance preparing for the battle ahead.

THRONE ROOM: ASGARD

Teams Avengers and Justice League entered the throne room of the citadel, only to see Doom sitting on his throne, waiting for them.

DOOM: Welcome heroes, I've been expecting you.

THOR: THOU SHALT NOT SIT ATOP MY FATHERS THRONE, VILLAIN!

IRON MAN: Where is Odin?

DOOM: Currently in Hel, being attended to by Hela.

BATMAN: What's your end goal here?

DOOM: Glad you asked, as we speak, Mr. Luthor is preparing our dominion over the world and there is nothing you can do to stop it.

SUPERMAN: How does he intend to do that?

DOOM: By using a Motherbox.

GREEN LANTERN: WHAT? IS HE CRAZY?

IRON MAN: I don't follow, what is a Motherbox?

SUPERMAN: A box that allows you to traverse through space as you see fit, it can also reshape the world into anything the user sees fit, with the right power source.

BATMAN: Superman, if Luthor's plan doesn't work, HE could have a direct gateway right to Earth, and invade again.

THOR: Who?

DOOM: NO ONE BECAUSE DOOM'S PLAN SHALL SUCCEED!

Doom then used his mystic gauntlets to blast at the heroes. Doom then summoned some robots to aid in this battle, the two opposing teams then began to fight.

LEX'S LAB: ASGARD

Luthor was working on the Motherbox, trying to open it. He then remembered his encounter with Darkseid.

(FLASHBACK)

Darkseid sat on his throne while Lex was on his knees.

DARKSEID: Why is this taking so long, Luthor?

LEX: I'm doing the best I can in my current situation, I can't have the others knowing I'm working with you.

DARKSEID: Ever since you merged the three dimensions together and I came in contact with you, I have been patiently waiting for results! You remember our deal?

LEX: Yes, if I open the gates to Apokolips, you would give me knowledge only a New God would know.

DARKSEID: Then do not delay. The gate had better be open in the next few hour's Luthor, or you I will make you wish you had never been born!

(END FLASHBACK)

Lex kept on working, hoping his plan would work.

THRONE ROOM: ASGARD

Doom and the heroes were in a ferocious battle to decide the fate of the new world, while everyone else fought off the robots, Doom and Iron Man were battling in the air. Doom grew tired of these games and decided not to hold back. He smashed Iron Man to the ground, Superman was about to punch him but before he made contact, Doom fired a Kryptonite blast at the man of steel, knocking him to the ground.

DOOM: I've prepared myself for you, Kryptonian.

Iron Man then tried tackling Doom to the ground, but Doom used his mystic abilities to create a shield blocking the armoured Avenger. Shazam and Thor then used their lightning against the villain, but Doom deflected it with his arcane gauntlets and then proceeded to blast the two lightning powered heroes.

DOOM: You see, there is no defeating me! I AM THE MASTER OF THIS WORLD!

Hulk then smashed Doom from above, but Doom had his shield prepared for the beast.

DOOM: Disgusting creature.

He then blasted the raging beast across the room. Things were not looking good.

WATCHTOWER

The Freedom Fighters were battling against the Death Egg Robot in a fierce battle for control over the Watchtower. Shadow and Sonic then spin dashed the Doctor from opposite directions stunning him, then Knuckles and Rouge used their own unique attacks against the robot with full force knocking the robot back. Eggman was not happy.

EGGMAN: YOU BOTHERSOME PESTS! YOU WILL NOT RUIN MY PLANS THIS TIME!

Eggman fought back with full force, but it didn't do him much good as the heroes just fought back harder and stronger. No matter what Eggman did, he knew that this was a losing battle, and he was not going to lose to that hedgehog again. So Eggman used his trump card, The Reality Stone. He bent reality to his will and summoned an army of Neo Metal Sonics to aid in this battle. Quickly the tides had turned into Eggman's favour as his army was quickly taking down the heroes one by one. Eggman began to cackle maniacally as he was certain victory was within his grasp. However Shadow had grown tired of these games and decided to take matters into his own hands. He Chaos Controlled behind Eggman and used his Chaos Spear attack on the mad Doctor, breaking his armour, Sonic saw what Shadow was doing and decided to act on it. He ran over behind Eggman and spun right through the robot, launching Eggman right out of it in the process along with the Reality Stone. The army of Neo Metal Sonics disappeared after that, the battle was won. Eggman wasn't done however, he had one last trick up his sleeve, he went to the control console and activated the teleporter, Sonic saw this and used his spin dash to stop him, but Eggman dodged the attack causing Sonic to hit the console. It started to malfunction and instead of just teleporting the heroes away, it teleported everyone away, not just the people on the Watchtower, but the people on Asgard as well. One by one everyone was teleported away to a different location.

ICE CAP ZONE

Everyone was teleported to the Ice Cap Zone, both heroes and villains. They stood on opposing sides of one another. But this wouldn't stop the villains from achieving their goals. Eggman summoned his Big Arms mech and entered it ready to battle, Lex was in his mech suit ready to fight and Doom used the Space Stone to summon an army of Doombots. Eggman held two Chaos Emeralds in his hands, but due to this oversight, all the Emeralds were in one place. Sonic and Shadow seized this opportunity and summoned the Emeralds together and began to power up. After their transformations, they were now in their Super States ready to fight. As they stood opposite each other, both sides knew that their final battle was about to begin.
