Spartan Leon Sikowsky (callsign Valiant One) was a UNSC Army trooper who fought in the final days of the Human-Covenant War. After the war's conclusion, Sikowsky was selected to become a SPARTAN-IV supersoldier, and was transferred to a new branch of the UNSC military known as Spartan Operations. Sikowsky was placed in command of Fireteam Valiant shortly after.

Biography

Early Life

Leon was born to Kaitlyn Sikowsky, a well-to-do delinquent teenage youth from New Alexandria, Reach who became pregnant at the age of fifteen after an alcohol-fueled one-night-stand with a young man (whom she would later be unable to remember due to how drunk she was) at a house party in 2531. Becoming pregnant however motivated Kaitlyn to get her life together for the sake of her unborn child. Supported financially by her parents, Kaitlyn put renewed effort into her schoolwork, enough to enable her to make up for her earlier poor grades and get accepted to a local university there in the city several years later.

From his birth, Leon was strange. He sometimes disliked being held as an infant. As a toddler, he would not play with his toys when others were around, and he preferred to organize his toys rather than to truly play with them as well. In school, he associated little with other children, and performed badly in his academics despite showing exceptional intelligence for his age.

Concerned, Leon's school had him tested for Asperger Syndrome, a form of high-functioning autism, and the results returned positive.

After his diagnosis, Leon was placed in a special education program, which gave him access to adaptions in his academics, and also taught him how to better socialize with children his age. Thanks to the help of this program, Leon was able to do well in school and make plenty of friends. However, Leon never managed to have much luck in dating during his adolescence, despite plenty of interest.

After graduating from high school, Leon decided to join the UNSC Army with his good friend Jacob Steinworth, who was determined to help keep the looming Covenant threat from reaching Earth.

Military Service

Human-Covenant War

Fall of Reach

Battle at Szurdok Ridge

Sikowsky fighting in the Szurdok Ridge.

After about one uneventful year following the completion of Leon's training, the Covenant finally arrived on Reach. A small special operations team discovered an enormous Covenant invasion force secretly massing in Ütközet, and Leon and Jacob found themselves being deployed as part of a massive offensive aimed at dismantling the Covenant invasion before it even began.

Early in the battle, Leon's Falcon broke off from the main assault force to aid in the destruction of several Covenant anti-aircraft guns that were preventing the Navy from providing vital air support. Leon's platoon was deployed at a Covenant-occupied BXR mining facility between the AA guns, and attempted to clear the building to allow ground forces to pass through it. However, the platoon quickly sustained heavy casualties, and were forced to evacuate the premises of the facility via Pelican. After dropping off their wounded at base camp, the remainder of Leon's platoon was redeployed to secure the ruins of one of the anti-aircraft guns, which had been destroyed by a lone specialist operator.

However, after the UNSC Grafton destroyed a Covenant teleportation spire and revealed a Covenant supercarrier in geosynchronous orbit above Ütközet, the UNSC began to hastily withdraw their forces from the region. Leon and Jacob were sent to their hometown of New Alexandria, which, being a major population center, would be a prime target for the Covenant invaders.

Siege of New Alexandria

Sure enough, New Alexandria fell under attack by four SDV-class heavy corvettes soon after the supercarrier over Ütközet was destroyed and Covenant reinforcements arrived in orbit. The Corvettes began to deploy Brute shock troops throughout the city, who quickly took control of key locations, while UNSC forces began working to move civilians to the city starport for evacuation. Worried about their ability to maintain effective aircover so long as the Corvettes loomed overhead, the UNSC's earliest evac efforts in New Alexandria attempted to use the city's underground transit system to move civilians.

Upon arriving in New Alexandria, Leon's unit was tasked with gathering civilians in one of the city's northeastern residential districts, loading them into vehicles and moving them to the nearest emergency vehicle access point to the subway station, roughly half a kilometer to the south. Civilians were ordered to gather at a local park in the center of the district, with Leon and his fellow soldiers working to maintain order as well as keep an eye out for Covenant attack. Operations proceeded smoothly for about two hours until the mid-afternoon when several Banshees passed overhead, firing a flurry of superheated plasma into the crowd below as they did so. The initial alien craft would fly out of sight as quickly as they appeared, but minutes later Spirit dropships began landing nearby, flanked by yet more Banshees.

Career Service Vitae

Sikowsky, Leon Spartan Team Leader FULL NAME: Leon Kurtis Sikowsky SERVICE #: 75526-26721-LS Unit: Fireteam Valiant Enlistment Date: 11/06/2550 Location: UNSC Vegas Gender: M Birthplace: New Alexandria, Eposz, Reach Birth Date: 05/14/2532 Blood Type: O+ Height: 205.74 cm Weight: 89.3577 kg General Notes Sikowsky has Asperger Syndrome, a high-functioning Autism Spectrum Disorder. While this impacts some of his skills regarding organization and social interaction, it does not affect him to such a degree as to significantly impair his performance as a soldier. Sikowsky is a perfectly if not exceptionally capable fighter and leader. Sikowsky's IQ and understanding of technical subjects are also well above average. As such, Sikowsky has been formally waived of any restriction to post or occupational specialty that would normally accompany an Autism Spectrum Disorder (ASD) diagnosis (see attached document 01D/03-2551). Sikowsky has been grafted into the SPARTAN-IV program [REDACTED] He has been placed in command of Fireteam Valiant, despite being one of the youngest and least experienced members of the team. However, Sikowsky is the most natural leader in the group, and the other members of Fireteam Valiant (with the possible exception of Spartan Corin Davis, though it should be noted that Davis has on multiple occasions been stated as being somewhat insubordinate) seem to trust his judgement. This trust is impressive, considering the reputations of some of his teammates (Spartan Davis is a decorated soldier whom has spent most of his career as an ODST, and Spartan Dorton is a former member of the highly exclusive 21st Fallschirmjäger Regiment of Germany's UNSCDF 6th Army). His place as Valiant's leader [REDACTED] Per request of Lieutenant, Junior Grade Colin-142, acting under the authority of CINCONI Admiral Serin Osman, Sikowsky and the rest of Fireteam Valiant have been indefinitely tasked under Operational Detachment-Sigma of the Office of Naval Intelligence Special Activities Division as of November 2558 (see attached document 14B/24-2558). Performance & Equipment During Valiant's time stationed aboard the UNSC Infinity, Sikowsky and his team all consistently ranked within the top 20% of Spartans aboard the vessel, and he was noted by superiors as being proficient in all simulation modes featured on the Infinty's holographic training deck. He has previously noted that he prefers the standard deathmatch-style modes known colloquially by Spartans as "Slayer", but performs well in all scenario types. Based on data gathered through the simulations, Sikowsky has historically favored the MA5D ICWS and the M6H PDWS heavily. Sikowsky used the Warrior variant of the MJOLNIR [GEN2] PAA, citing the variant's operational flexibility as its primary appeal. He also utilized an upgraded VISR 4.05, which prevents moisture from adhering to the visor, so that it does not freeze and limit visibility in subzero conditions. [REDACTED] Fireteam Valiant and the rest of Operational Detachment-Sigma were provided with [GEN3] MJOLNIR armor systems in July 2559. Sikowsky requisitioned a mostly standard set equipped with the Cavallino helmet system, outfitted in a similar fashion to his previous WARRIOR-class [GEN2] armor. Service History [REDACTED] Special Notice[s] Spartan Leon Sikowsky filed a Personal Relationship Form on October 30, 2556 (see attached document 07E/21-2556), and is thus officially recognized by the United Nations Space Command Defense Forces as being involved in a romantic non-marital relationship with UNSC Navy civilian attaché Dr. Annette Darvinshire. As such, Spartan Sikowsky and his partner are obligated to conform to all official UNSC codes and regulations relating to personal relationships of this nature. As of this date (March 3, 2560) no violations have been made by Spartan Sikowsky and/or his partner, nor have any request[s] for a termination of this contract been made to date.

Personality & Traits

"I met some real Spartans back during the war, you know. Man, when I think about them, sometimes I wonder if us IVs are just Spartans in name only."

―Sikowsky, on the differences between the SPARTAN-IIs and the SPARTAN-IVs.

Unlike many early SPARTAN-IVs, Sikowsky did not allow his newly-gained Spartanhood to change him or his behavior, and looked down upon Spartans who became overconfident as a result of their newfound abilities. Sikowsky tried to model himself after the Spartans of Sapphire Team whom he'd fought alongside during the war, and he encouraged his comrades to behave similarly.

Due to his Aspergers, Sikowsky sometimes struggled with maintaining his patience, as well as with paying attention to small details in non-critical aspects of his career and day-to-day life. Though these problems would slowly improve over time, they would remain areas of weakness for him throughout his military career. However, he proved to be exceptionally capable at thinking on his feet, able to conjure solid plans and tactics even while under intense stress and pressure. While not coming to him naturally, Sikowsky had subconciously trained himself throughout his youth to become quite skilled at reading both people and situations, something which helped him greatly as a soldier and a leader.

Socially, Sikowsky fared well, appearing mostly normal. However, he did exhibit a few quirks, such as a tendency towards overenthusiasm, and some extremely minor obsessive-compulsive habits. While his friends and teammates became accustomed to these things, and a few, such as Annette Darvinshire, even found these traits endearing, others like Sarah Palmer found these habits annoying and would lose patience with Sikowsky very quickly.

Equipment

Suit Name	Image	Time Worn	Description	Status
RECRUIT-class MJOLNIR		December 9, 2554—April 21, 2555	Issued to all newly-augmented SPARTAN-IVs, RECRUIT-class MJOLNIR is designed to allow one's body to adjust to the stresses of wearing the MJOLNIR PAA. Rather than use the standard steel and gold scheme of the rest of Infinity's Spartan contingent, Sikowsky customized his suit with a steel and dark green color scheme in a unique pattern, although this customization remained compliant with UNSC Equipment Code 20.00.62.	Recycled
WARRIOR-class MJOLNIR		April 21, 2555—July 15, 2559	After graduating from the Recruit armor, Sikowsky was presented with the option to either keep fielding the Recruit armor, or transition to one out of a small list of MJOLNIR variants selected specifically for him. Sikowsky ultimately chose to transition to WARRIOR-class MJOLNIR, commonly considered by many to be the [GEN2] platform's baseline variant, and easily its most popular. This armor variant allowed for exceptional speed and mobility, while at the same time allowing for minimal compromise in regards to protection. Sikowsky retained the steel and dark green scheme from his previous Recruit armor, and also added the VISR 4.05, or the "Frost" visor. In May 2558, this armor was upgraded with an integrated thruster pack as part of a system-wide update. Additionally, after transferring to the UNSC Orphellion in July 2558, Sikowsky would repaint his armor, using a new pattern and two different shades of green instead of just one.	In Storage

Trivia

• After transferring to the UNSC Orphellion, Sikowsky repainted his MJOLNIR [GEN2] armor. This explains the difference between his armor's paint scheme in Halo 4 and Halo 5: Guardians.
