Feats

Able to take on a platoon of Decepticons

In an alternate universe, Optimus Prime killed Megatron in his battle in Autobot City and not died, because Kup managed to stop Hot Rod, so this did not enter the fight. (Transformers: Deviations)

He, with assistance from the Last Autobot, was finally able to win the war against the Decepticons.

Defeated Megatron while fatally wounded

Brought back as a zombie by the Quintessons, only to break their control and give up his second chance at life to go in a suicide run in a shuttle to destroy their fleet, and his body was still intact after the resulting explosion

Cured the Hate Plague across the universe via the Matrix of Leadership

Gave his life to stop the Swarm, filling it with Primus' vision of the Transformers via the Creation Matrix, thus changing its mentality to beings of creation and restored Prime to make amends

He, along with Megatron, saved the universe from and were forced to kill Shockwave

Defeated the combiner Menasor single-handedly

Officially annexed Earth into the Council of Worlds

Killed Demolisher, Grindor, Bonecrusher, The Fallen, Driller, Shockwave, Megatron, Sentinel Prime, and Lockdown

Weakness

Versions of him across the Transformers multiverse have, at some point, died at least once

His compassion for all forms of life can be used against him

Like Superman, he holds back his full strength as he is afraid to harm those around him or even the planet he's on

He was almost killed twice by Sentinel Prime and Lockdown

Often abandons his moral code completely and brutally slaughters his enemies if he wants to.

Often shows up late to battles that he easily wins

Inaho Kaizuka

Great Intelligience

Excellent Pilot

Skilled Tactician

KG-6 Sleipnir

Stabilizers

A set of wings and small thrusters attached to the legs that allow the Sleipnir limited hovering ability, when active both open up into an "X" shaped array of wings with two wings on the side of each leg. They can also be used as a shield, but the destruction of the stabilizers impairs the Sleipnir's ability to hover and possibly it's ability to walk and run as well.

Grappling Hook

The Sleipnir is seen using a wired grappling hook with a arrowhead-like hook, it is deployed from the wrist near the joint connecting the hand.

Tactical Suit

The Tactical Suit is a set of add-on Reactive armor plates around the forearms and chest of the Kataphrakt. (AZ: "Phantom of the Emperor")

Belisalius Conformal Power Assist System (BAH-1X)

The Conformal Power Assist equipment has a set of maneuvering and stabilizing thrusters, missile carriers. As a whole it is acts as armor.

Parachutes

A parachute can be deployed from shoulder armor.

Armaments

75 mm Cannon w/Grenade Launcher

A bullpup rifle that serves as the Sleipnir's main armament. It's capable of firing High Explosive Incendiary (HE) or Armor-piercing Shell (AP) rounds depending on the situation. The cartridge is rectangular-shaped and is loaded horizontally right in front of the trigger.

Sniper Rifle

It is produced by "Clibanarius Defence Alternatives", a defense contractor for the United Forces of Earth.

Pistol

Although the Slepnir itself does not utilize a pistol, Inaho once used the pistol of Inko's Areion.

Knife

A short tantō knife is stored in the backpack of the Sleipnir and acts as its main CQC weapon of choice.

It is produced by "Clibanarius Defence Alternatives", a defense contractor for the United Forces of Earth.

Space Load-out

Recoil-less Cannon

In space battles, Sleipnir are equipped with high-caliber long-barreled recoil-less cannons, which directed the back blast of rounds out the back of the weapon when fired. This served to keep the craft stationary, even when drifting in the middle of space. In battle they were capable of firing high-explosive rounds.

Blades

A Sleipnir can store several blades in the containers that made up their "wings."

Grappling Hooks

A Sleipnir can be equipped with grappling hooks, allowing them to maneuver in the Satellite Belt.

Feats

Able to pilot his KG-6 Sleipnir despite minimal training

His use of grenade launcher rounds that produce heat to counter an advancing enemy Kataphrakt while going through the enormous ice-field it had produced.   

Raised his own sister Yuki despite being the youngest of the two

He is the only character who has successfully defeated a Martian .  

Able to defeat multiple Martian Kataphrakt pilots by combining his strategy and cunning with his sheer piloting skills.  

Weakness

Anti-social

Unable to relate with others and expressing himself although he has gotten over that weakness

Unable to express his emotions well

Usually criticized for not sharing his plans with others and only capable of giving orders

At a young age, he badly injured his childhood bullies, resulting in him and Yuki being forced out of an orphanage into a Government paid apartment

Although the KG-6 Sleipnir is Earth's most sophisticated weapons, they are too primitive compared to their Martian Counterparts

Before the fight, let's all wish MothGoji a happy birtday

Fight

Space, 5 km away from the moon

Deep in the dark cold void of space, all seems to be silent as asteroids and satellites drifts aimlessly in space.

However, a KG 6 Sleipnir flies across the void, surveying the area.

Inside

Inaho Kaizuka stares at the computer screens, scanning through the area.

Just then, the computer screen flashes, broadcasting Yuki's face on it.

Yuki: Find anything Inoha?

Inaho: Nothing so far.

However, just then, something on the moon caught his eyes, causing him to squint them for a closer look.

Yuki: Inoh?

Inaho: Hold on Yuki, I found something.

Moon

As the KG 6 Sleipnir flies towards the moon, Optimus sat on the rock, staring at the blue and green sphere below him.

Optimus: All seems to be well.

However, just as Optimus stood up, all of a sudden, he heard a loud thud from behind.

THOOM!!!!!

Optimus spun around, only to find a huge massive humanoid robot facing him.

Optimus: Who are you? What do you want?

The KG 6 Sleipnir faces the Autobot and Inaho replies.

Inaho: You must be a spy sent by the Martians aren't you?

Confused, Optimus said to him.

Optimus: I haven't the faintest idea what you are talking about.

The KG 6 Sleipnir then draws out it's pistol and Inoha said.

Inaho: Very well. I shall deal with you myself.

THOOM!!!!

Optimus launches himself forward just as Inaho opens fire.

THOOM!!! THOOM!!! THOOM!!!

Optimus jumps across the area, dodging the machine's gunfire before launching himself upwards.

Just as Optimus throws a punch, the KG 6 Sleipnir swerves it's head back, dodging the blow before throwing out a downwards punch.

WHAM!!!!

Optimus: ARGHHH!!!!

Optimus grunts out as he falls back onto the ground.

THOOM!!!!

The KG 6 Sleipnir points it's Sniper Rifle at the Autobot and it opens fire at him.

THOOM!!!

Optimus looks back and he rolls across, the floor, dodging the attack.

KABOOM!!!!

As Optimus pushes himself up, he draws out his Laser Blaster and he opens fire at the flying machine.

POOM!!! POOM!!!

The KG 6 Sleipnir swerves to the side, dodging the blast, only for the second blast to suddenly strike it.

BOOM!!!!

Inaho: ARGHHH!!!!

Inaho screams out as the entire robot shook from the attack.

Optimus races forward, activating his Blaster Cannon before launching a blast at it.

THOOM!!!!

KABOOM!!!!

Inaho: WHOAAA!!!!

Inaho screams out as the KG 6 Sleipnir was sent tumbling down from the attack.

WHOOSH!!!!

The KG 6 Sleipnir activates it's stabilizers, stopping it from falling.

CLICK!!!!

The KG 6 Sleipnir draws out a Recoiless-Cannon and it points it at Optimus.

Optimus looks up and he said to the machine.

Optimus: Give it up. I do not wish to harm you.

Inaho: Your tricks won't work on me Martian.

THOOM!!!!

The robot opens fire at Optimus, launching a powerful explosive projectile right towards him.

Just as the projectile struck onto him, it lets out a massive explosion, blasting Optimus back.

KABOOM!!!!

Optimus: ARGHHHH!!!!

Optimus screams out as he was sent flying back from the attack.

WHOOSH!!!!!

The KG 6 Sleipnir swoops forward, ramming right into the Autobot.

BAM!!!!

As the machine is flying, Optimus draws out his Laser Gun and he points it at the machine before opening fire into it's chest.

THOOOM!!!!

KABOOM!!!!

The KG 6 Sleipnir recoils back just as the thrusters on it's chest explodes, sparking out electricity.

Optimus throws a punch right across the robot's face, striking it across it's faceplate.

WHAM!!!!

Optimus then swung his arm up, throwing an uppercut.

WHAM!!!!

The Autobot then draws out his Ion Cannon and he opens fire at the KG 6 Sleipnir.

THOOM!!!!

KABOOM!!!!

Inaho: ARGHHHHH!!!!!

Inaho screams out just as the KG 6 Sleipnir's chest explodes from the attack.

WHOOSHHH!!!!

The KG 6 Sleipnir flies up into the air, flying across the Autobot.

Inaho: This isn't over!

The KG 6 Sleipnir whips out it's Grenade Launcher and it opens fire at him.

THOOM!!! THOOM!!!

Optimus narrows his eyes as he swerves to the side, dodging the explosive projectiles raining from the sky.

KABOOM!!! KABOOM!!!!

Optimus whips out his Energon Axe and he ducks just as the KG 6 Sleipnir fires another explosive at him.

WHOOSH!!!! KABOOM!!!!

Optimus sprints across the ground, running past the KG 6 Sleipnir before dashing up a rock.

As the reaches the peak of the rock, Optimus launches himself upwards, flying right towards the KG 6 Sleipnir.

Inaho: What?!

Before Inaho knew what was happening, Optimus swung his Energon Axe right across the KG 6 Sleipnir's blades, disabling it's wings.

SLASH!!!!

KABOOM!!!!

Inaho: AAAHHHHHHH!!!!!

Inaho screams out as the KG 6 Sleipnir was sent spinning in the air, flying out of control before crashing right onto the ground.

BOOM!!!!

Optimus raises up his hands just as his feet slams right onto the floor.

THOOM!!!!

Optimus looks to the side and he stood up, facing the damaged robot.

Optimus: Are you ready to surrender?

Optimus questions Inoha just as the KG 6 Sleipnir pushes itself up.

Inside

Inaho pants in exhaustion just as blood flows from the top of his head.

BOOM!!!

Sparks explodes around the control panels, it's engines badly damaged from the fall.

But the KG 6 Sleipnir still have some fight left in it.

Inaho presses a button and he said to Optimus.

Inaho: Never. As long as I live, you will never touch my home planet.

Outside

SHING!!!!

The KG 6 Sleipnir swung it's arm downwards, brandishing it's knife.

The KG 6 Sleipnir puts it's fist into it's palm before bending down, performing a psuedo bow before getting into a fighting stance.

Optimus stood back and he bows back in respect before raising his Energon Axe upwards.

Optimus: You fight well human. For that, I shall give you an honourable death.

Both robots faces each other, neither moving from their place.

Space rocks drifts past them as the two narrows their eyes, their grips around their weapons tightens.

After what seems like forever....

WHOOSH!!!!

Both the KG 6 Sleipnir and Optimus launches themselves forward and a loud slashing sound cuts through the air.

SLASH!!!!!

Silence broke through just as Optimus and the KG 6 Sleipnir faces opposite each other, their weapon hands outstretched.

Both stood in their place, not moving an inch.

As the two stood there, a meteorite drifts through the dark void of space before hitting a space rock with a light tap.

Tap!

Suddenly.....

KABOOM!!!!

Optimus shuts his eyes just as the KG 6 Sleipnir's chest explodes, causing the robot to crumble onto the ground.

BOOM!!!!

Optimus stood up and he looks back, staring at the damaged sparking remains of the robot.

Optimus turns back and he steps forward, approching the fallen robot.

He then bends down and he grabs the control room of the KG 6 Sleipnir before ripping it out of the robot.

PSHHHHH!!!!

The Autobot stares in solemn silence as he looks at Inaho, who was rendered unconscious from the attack.

Optimus: I purposely kept away from the controls to spare you human. I shall return you to Earth.

Optimus then tosses the control room down towards the planet, watching as it slowly shrinks and disappears as it enters the globe.

Optimus Prime then turns around, solemnly staring into space as he said.

Optimus: You were a fomidable defender of the planet but rest assured, the Autobots will defend your people at all cost.
