((Assuming I can drop in using a character from an already established universe uvu)) 
Name: Robert-016

Gender: Male

Age: 27

Appearance: [MJOLNIR Armor](http://imgur.com/9uNdVF7)

World: UNSC Controlled Space, Earth, Alternate Universe

World Description: The UNSC controls a large portion of space with the capitol of Planet Earth.

Power: SPARTAN II Augmentation + MJOLNIR Powered Armor

Power(s)' Description: The augmentation and training granted to Candidate 016 has catapulted him over every normal human subject, and his armor amplifies his combat efficiency.
Speed- Spartan Robert maintains an average speed of 40 MPH, and brief bursts of 55 MPH by temporarily overloading MJOLNIRs speed capacitors.
Strength- Robert has strength that has never been properly measured, due to danger to the trainers. In the field, Robert has shown the capacity to flip a 66 ton M808 Battle Tank over, lift 15 metric tons of equipment in a non-combat scenario, with possibly more strength when under pressure.
Reaction Time- Just under fifteen miliseconds in combat. Robert has been reported to occasionally see things happening in slow motion, during what is called "Spartan Time."
Training- Robert has received advanced military training since the age of six. He is able to out-think his opponents more often than not, and has the skill and ability to preform countless advanced combat maneuvers. Master of hand-to-hand combat as well as ranged, Robert can also adapt to learn new weapons to strategies quickly.
MJOLNIR Armor: MJOLNIR armor is a major key to his success. It allows him to achieve the strength and speed listed, and is also equipped with a regenerating energy shielding system that can take a small amount of damage, titanium-A armor plating, and magnetic plates for his weapons. The armor also have biofoam injectors that heal his wounds after a period of time in which no damage was taken(one min. or more w/o damage).

Equipment:
-MA5D Assault Rifle: Semiautomatic weapon. 32 round magazine, he carries 224 rounds extra into battle with him(total of 8 magazines, counting the one already loaded.)
-M6H Pistol: High-powered sidearm, good for headshots. 8 rounds to a magazine, 32 rounds extra. (5 mags total)
-SPNKR Rocket Launcher: Rocket launcher, fires rockets at high velocity. 6 rockets total, only two may be loaded at a time. 

Weaknesses:
-if MJOLNIR is EMP'd or sufficiently electrocuted, it will stop running, causing Robert to be severely impaired and nigh motionless in a fight.
-Sufficient damage will destroy MJOLNIR and its occupant.
- There's always the possibility of running out of ammo.
-The idea of 'powers' is completely new to Robert, and in the first five or so minutes of a fight they may be taken advantage of before Robert beings to understand their limits.

Backstory:
Robert was born on planet Earth. He lived a normal childhood until age six; when he was abducted by the Government. The Office of Naval Intelligence decided they needed a team of badasses stronger than an entire platoon of marines- Their answer was The SPARTAN II program. Robert, along with his companions, were trained to be the deadliest force in the galaxy- And they were. They were augmented and given power armor- Then they were next to unstoppable, destroying many operations by the insurrectionists. Unstoppable until the Covenant came, anyway.
The Covenant were a race of aliens bent on destroying humanity. The Spartans, Robert included, fought hard. The war went on for years, but eventually, thanks to the efforts of another Spartan, it was won. But many of Roberts friends were dead. He was reassigned from the Navy to a new branch, the Spartan Branch. After a few successful missions he was visiting an ancient alien site, accidentally activating some technology. This technology zapped him to some alternate universe- Where he was told he was a 'champion'. He didn't know what that was supposed to mean, but he knew what he'd use his wish for- To get back to UNSC controlled space.
