Even with Thor and the Pillars on their side, the defenders of Canterlot were still being overpowered by the invading forces. From the northeast wall, Tempest Shadow and Razzle Fizzle watched as the army fought valiantly along with the rest of the wall's defenders.

But they didn't watch for very long as they saw a group of Donkeys and Evil Changelings heading towards them.

"Incoming!" shouted Shining Armor. "Attack!"

Firing barrages of magic and weapons, the Northeast wall defenders blasted at the invading forces, sending them back. However, Razzle's lack of fighting concerned Tempest greatly. Her aim was off, her fighting prowess was not as strong as hers. Right away, Tempest finally realized the reason for her sister's decision to fight.

"Razzle, are you seriously wanting to die?" Tempest thought to herself as the thought crossed her mind. "Is that why you wanted to fight?"

Those were the thoughts that went through Tempest's head time after time as the fights intensified. Using whatever magic was inside her broken horn, Tempest fired spell after spell at her attackers, sending them back and killing with her eyes still locked on her sister.

…

Back on the battlefield, the remaining Avengers and Guardians of the Galaxy continued to also fight as valiantly. Now, Tirek and Cozy Glow were also on the battlefield, striking down Wakandan and Equestrian soldiers. Then, they confronted Starswirl the Bearded.

"Well, well," laughed Tirek, looking right at Starswirl. "We meet again, Starswirl."

"You still haven't learned anything," cried Starswirl, firing a blast of magic at Tirek which he merely absorbed and consumed in strength. Firing a blast of his own magic from his horns, Tirek had his attacked deflected by Starswirl and instead striking at several Storm Creatures and Donkeys. "You will never have the magic of Equestria."

"It's more than magic we are after," snapped Cozy Glow, flying down and kicking Starswirl in the face, knocking him down to the ground. "Face it, Starswirl, you are just second best."

"Never!" roared Starswirl, firing a blast of magic at Cozy Glow, nearly striking her. The young Pegasus filly and her mentor kept their eyes locked on Starswirl until they were knocked back by a barrage of gunfire from Bucky and Rocket. "Thanks, rabbit."

"I'm a raccoon, beard horse," replied Rocket as they returned to fighting. "What is with him?"

"He's senile," answered Bucky. "Just concentrate on the enemy and don't ask for the gun or the arm."

"If you say so," muttered Rocket. "I'm still gonna get that arm eventually."

…

At the same time, Mistmane and Somanmbula were aiding Romanoff and Spider Woman in fighting a combination of Sombra's and Chrysalis' forces. The two mares and two female humans had their hands full in fighting.

"Behind you!" cried Spider Woman as Mistmane turned around to see a soldier of Sombra charge towards her. The old unicorn used a shield spell to protect herself from the soldier and fired a barrage of blasts at them.

"You know, for an old mare," remarked Romanoff, amazed at how Mistmane was able to handle her own. "You sure know how to fight well."

"Thank you, dear."

But a swift kick to the face by a changeling sent Mistmane back down to the ground. Somanmbula retorted by picking the Changeling up and tossing him into the air, causing him to be hit by a barrage of missiles from the Wonderbolts, killing him.

"In fact, I stand corrected," remarked Romanoff again before being taking down by several evil Changelings.

…

Back on the northeast wall, Tempest and the defenders continued to hold their own with casualites being taken on both sides. However, Tempest felt that her sister needed to be taken out of harm's way.

"Razzle!" cried Tempest, trying to reason with her. "This is crazy! You've got to take shelter now!"

"Get off me, Fizzlepop…" Razzle started to reply, only to be taken down by several soldiers which Tempest managed to shake off.

"You want to be with mom and dad, is that it?!" cried Tempest. "That's why you wanted to fight, the real truth? To get yourself killed?!"

"Fizzlepop…" cried Razzle Fizzle, much to Tempest's shock. "I…I…"

Just then, a loud blast and a rumbling sound rocked the wall and shook down everypony. Without warning, parts of the wall started to collapse, taking both invader and defender down onto the streets of Canterlot. Helping her sister to her feet, Tempest now had a different mindset: she needed to protect her sister at all costs.

"Fall back!" shouted Shining Armor in a panicked voice as the defenders began to pull back from the wall. Nevertheless, the invaders kept coming now being backed up by Storm Creatures.

Racing down onto the streets, Tempest attempted to drag her sister to a safe place, only to make a shocking discovery that made Tempest feel sick to her stomach.

"Well, well," laughed the Storm King, alive and determined to finish off his former lieutenant and her sister.

"You should have killed me," snarled Tempest, her horn glowing with anger over being used by him.

"It would have been a waste of parts!" cried the Storm King as he and Tempest charged towards each other while Razzle Fizzle watched. "You fight strong, Commander Tempest. But you could never make the hard decisions!"

In a bold move, the Storm King struck Tempest in the face with his staff, scratching her eye and giving her the same scar as her other one.

"Fizzlepop!" screamed Razzle Fizzle, but the Storm King didn't care. He had death in his eyes and that death was aimed at Tempest. Acting fast, Razzle Fizzle charged and fired a blast of magic at the Storm King, hitting him in the side. Before she could lay a hoof on him, however, Razzle was also struck down at that moment, much to Tempest's horror.

There standing before her and Razzle was Proxima Midnight.

"You could use some assistance," she laughed, looking up at the Storm King, who smiled and proceeded to return in finishing off Tempest.

"Thanks," replied the Storm King, aiming his staff right at Tempest, Fearing the worst, Tempest now had a major conflict on her hooves: fighting both her former superior who took advantage or trying to protect her sister from Proxima Midnight's wrath.

…

Back at the Castle of Friendship, the rest of the Avengers and the Guardians of the Galaxy continued to hold their own against Grogar and the Mean Six. However, fighting against a demonic monster like Grogar was beginning to take its toll. Struggling to her feet, Twilight coughed up some blood as she tried to figure out a way to strike at Grogar again.

"You okay, Twilight?" asked Iron Man, to which Twilight silently nodded. "How the hell are we going to get this guy?"

"Pathetic fools," remarked Grogar, his horns glowing. "Your efforts are futile against me. Why don't you just surrender to me now?"

"Never," coughed Dr. Strange, cuts and bruises now all over his body from being tossed around.

…

Suddenly, they heard a loud roaring sound from inside the Castle of Friendship and breaking through a window was the Hulk, ready to join in the fight.

"You are so screwed now, goat," whispered Dr. Strange, his spirit restored from the Hulk's arrival.

…

But the question remained on everyone's mind was would they be able to defeat Grogar despite their growing injuries and the arrival of the Hulk himself?

The answer to that question would be found out in due time…
