The human empire fleet, including the allied civilizations has gathered, forming a fleet of two million. This is the full might of the human empire, Spartans, super soldiers, Astartes, and even the custodians who were previously injured rejoined the battle.
Suddenly, a voice echoed through space. It was the emperor of humanity, Erskine himself.
"Today, humanity shall face a threat that may very well cause its extinction. "Erskine paused and continued his voice louder.
"HOWEVER, WE ARE HERE UNITED, ALL-POWERFUL IN OUR FULL GLORY, WE ARE HUMANITIES FIRST AND LAST LINE OF DEFENCE, WE ARE ITS ETERNAL PROTECTORS, WE ARE THE SWORD, WE ARE THE SHIELD, AND WE WILL PREVAIL!
WE DO NOT BUCKLE OR YIELD UNDER OVERWHELMING FORCE. WE OVERCOME IT! WE SURPASS IT.
WE WILL TRESPASS INTO THE DOMAIN OF THE GODS! AND USE THAT MIGHT TO DEFEAT OUR FOES.
Suddenly, in the deep space, a gigantic human skull made of darkness appeared, with its hollow eye sockets glowing a crimson red, the fleet of the human empire, including the enemy fleet could see it, then it disappeared and a gigantic shadow figure appeared holding a scythe, and then it raised its gigantic hand and pointed with its finger at the enemy fleet, and then an extremely loud deep distorted voice echoed through space.
"CHARGE!"
The whole human fleet, including the allied civilizations charged towards the enemy fleet. The Ancient One, Eldrin, Erskine and Sebastian led the charge.
The Enemy fleet started firing; 5 million out of 40 million spaceships fired their blasts simultaneously.
In the human empire's mothership stood several figures, who were the presidents of all the nations of the human empire, serving under the emperor.
The Japanese president, who wore futuristic samurai armour, spoke.
"I suggest we use the tesseract force fields now; arc reactor-powered ones won't withstand so many blasts."
The other presidents nodded in agreement, and Colonel Phillips, President of America, wearing a futuristic black armour said.
"Should we use the tesseract-powered atomic bombs?
The President of China, wearing a black and red futuristic armour that covered his whole body, along with his head, and with a black and red metallic conical hat, spoke.
"Those bombs are way too unstable; they would cause casualties on our side if they were to be used. I suggest using them only if there is no other option left, if the emperor agrees of course"
The human fleet, including the allied civilizations, activated their tesseract force fields easily withstanding the combined blasts of the 5 million spaceships that fired them, and naturally retaliated by firing tesseract-powered blasts, successfully taking out three hundred thousand spaceships from the enemy fleet, but they won't be able to use tesseract-powered blasts for quite a bit due to the immense energy consumption.
Both fleets started firing waves of energy blasts at each other. The human empire used their strongest arc-powered weapons, though not nearly as powerful as the tesseracr-powered ones but under constant fire, every force field could break. It took a while, but the enemy fleet started losing spaceships due to the arc-powered weapons, but it wasn't really alarming for them.
Eldrin was the first to reach the enemy fleet; he was constantly being bombarded by more than two hundred thousand spaceships, but thanks to his teleportation capabilities nothing hit him. He spun around and swung his scythe horizontally, sending a huge dark slash made of darkness imbued with the power of dark magic. It cut through thousands of spaceships like they were made of paper; they phased through their force fields and then turned solid and cut their ships in half.
Erskine used his authority of space to create a small black hole that sucked thousands of spaceships, taking them somewhere even he didn't know. He also used his now empowered telekinesis to pull even more spaceships to the black hole.
The Ancient One cast all kinds of magic spells, portals to the mirror dimension, trapping thousands of spaceships there, magic bombs that annihilated even more spaceships, and she also conjured gigantic constructs and weapons once in a while.
Sebastian was manifesting portals in front of the enemy fleets' blasts, sending them back to them and causing casualties too.
But the enemy fleet, with their overwhelming numbers and energy weapons eventually started breaking the tesseract force fields of the human empire, causing casualties.
Above the human empire's mothership was a giant cannon, which was a prototype weapon meant to harness the energy of the power stone and turn it into a powerful beam. It suddenly started glowing purple, until it illuminated the surroundings and then the purple beam came; in a mere moment, the enemy fleet lost six hundred thousand spaceships, but unfortunately this weapon had a long cooldown time of one hour. It could be used constantly, but it would start falling apart due to the cannon's inability to withstand a constant stream of the power stone's destructive energy.
Hundreds of thousands of Astartes flew through space with cloaking technology,and each infiltrated spaceships from the enemy fleet with the goal of wiping out the passengers and pilots,and destroying the spaceships.
Hundreds of thousands of small spaceships with cloaking technology and filled with Spartans were responsible for infiltrating the spaceships of the enemy fleet and installing tesseract-powered bombs in them.
Super soldiers with their increased cognitive capabilities formed all those plans, gathered intel and information on the enemy's possible weaknesses and capabilities, and made assassination plans for important figures of the enemy fleet.
The Wakandians, with their modified spaceships capable of absorbing enemy attacks, were perhaps one of the most annoying opponents to deal with. You can't hit them; the attacks get absorbed only to be sent back to you even stronger. It was a combination of absolute defense and absolute offence; their spaceships were fewer but were made of pure vibranium, including their mothership.
The Talokans, although powerful too, are not specialised for space battles, but their ships were also made of pure vibranium, making them essentially just as much of a headache as the Wakandians.
