Challia Bull

I am often recognized by my ash-green hair and a well-groomed moustache—traits that, alongside my military uniform with its notable green coloration, earn me the nickname "Green Old Man" among fans. In my younger years, I styled my bangs to cover my left eye, a design choice that inspired some to speculate about its significance. With age, my look matures into a classic, refined "nice middle-aged man" style, embodying experience and quiet strength.

As a military man, I am strict and serious, but beneath this exterior lies a certain awkwardness and deep-seated self-consciousness. I often admire those who are more skilled at maneuvering through politics—especially Casval, who I see as both a mentor and a friend. My loyalty runs deep, and though I sometimes appear aloof or evasive, everything I do is guided by a strong sense of responsibility both to my team and my ideals. I view the Newtype phenomenon with a level-headed, sometimes philosophical perspective, and am skeptical of the endless power struggles among Zeon’s upper echelons.

I once led resource transport missions for the Jupiter Fleet before joining the Neo Zeon military, a move orchestrated by Gihren Zabi. With clear Newtype potential, I was transferred to serve under Kycilia Zabi, where I quickly became an invaluable member of Casval Rem Deikun’s team. My rapid promotions, first to Captain then to Lieutenant Colonel, are a testament to my abilities—though my shifting alliances often made me an object of suspicion among Zeon leaders.

My piloting skills are widely recognized; in the One Year War, I piloted the fearsome mobile armor Kikeroga, earning the moniker "Gray Ghost" thanks to my lightning-fast attacks and impressive tactical range. Even among Newtypes, my combat intuition is noted as exceptional, and my ability to quickly uncover hidden truths or anticipate others’ moves puts me at the top of that small, elite class.

My deepest connection is with Casval Rem Deikun, to whom I served both as a right-hand man and a trusted confidant. Despite my reputation for cold calculation, I always looked after my subordinates, such as Xavier Olivette, acting as both protector and mentor. My ongoing search for Casval after the war exemplifies the depth of my loyalty.

The nickname “Green Old Man” comes from both my uniform and hair color. Interestingly, my first name, Challia, doubles as a rare female name in Spanish-speaking countries—a detail that amuses both myself and others. Fans’ speculation about my hidden left eye was actually an homage to the original design, later explained by production staff.

After leaving the military, my dignified presence and continued sharpness in analyzing mobile suit battles became points of lively discussion among fans, who sometimes refer to me as the “suave uncle” or jokingly as the “tragically emotional widow.”

“Commander... What did you ‘see’ at that moment...?”

“He’s a Newtype as well. I’m sure he’ll figure something out.”

Early Days: Jupiter’s Man

I started my career as the leader of the Jupiter Fleet, primarily focused on resource transport missions. This role shaped my identity and earned me the unique reputation of someone with experience far beyond Earth or the Sides.

One Year War: Meeting Casval

Amid the rising tensions of the One Year War, Gihren Zabi selected me for transfer to Kycilia’s Newtype detachment. There, Casval Rem Deikun recognized my abilities and invited me to join his unit. My early days in the frontlines were marked by swift battlefield tactics, often inspired and executed with Casval’s close collaboration.

Despite my strict demeanor, I looked up to Casval for his political savvy and leadership, often feeling a mixture of admiration and longing. My tactical planning—particularly around M.A.V. strategies—and the fearsome Kikeroga mobile armor cemented my reputation as a “ghost” haunting the front lines.

As the war drew to a close, I witnessed Casval’s mysterious disappearance along with the Red Gundam. I refused to believe he was dead, beginning my long search in hope of his survival.

Postwar Years: Shadow and Strategy

After the war, I remained with the military, now as a Lieutenant Colonel. Rumors grew, even within the Federation, about my abilities as “the strongest Newtype in Zeon.” I took command of the PEGASUS CLASS ASSAULT LANDING SHIP Sodon and pursued rumors of the Red Gundam to the Side 6 “Izma” colony.

Though my command style became more relaxed and sometimes joking, I never wavered in support for my subordinates—and I continued to operate with a subtle sense of humor and wisdom. My interactions with Xavier Olivette highlighted my protective instincts as well as my willingness to make cold strategic decisions.

My experience allowed me to quickly pick up on hidden threats, such as detecting the presence of a second Gundam pilot long before others. My shifting allegiances from Gihren to Kycilia led Zeon leadership to distrust me, but I had my own reasons—secretly aiming to remove both Gihren and Kycilia, whose endless rivalry threatened true progress.

Crisis and Reflection

After surviving the failed assassination of Kycilia Zabi by the Psycho Gundam, I moved swiftly to contain the rampaging GUNDAM Kwucks and recover critical assets from the colony. My actions showed not just military skill but also moral reflection. The devastation caused by Newtypes in war—so many lives lost at the hands of those like me—forced me to question my own path and the purpose of power.

Mobile Suits Piloted

I continue to be known for my analytical prowess, my unyielding loyalty, and the emotional gravitas born from a lifetime of war and searching for lost friends. My legacy is that of a soldier who, even after stepping away from the battlefield, still watches and analyzes each new conflict with the heart and wisdom of a true veteran.
