Maximilian Jenius, known as Max, was born in Europe and joined the U.N. Spacy at 16. When assigned to the Vermillion Team under Hikaru Ichijyo during Space War I, he held the rank of Corporal with an A skill rating, 320 simulator hours, and 50 flight hours. His combat style featured unconventional handling of Variable Fighters, prioritizing rapid form shifts over dogfights and favoring Battroid mode for precision shooting. He demonstrated tactical ingenuity, such as disguising his Valkyrie in a Zentradi uniform to evade capture on reconnaissance. Reserved yet strictly adhering to protocol, he sometimes interpreted orders literally, conserving ammunition through near-perfect accuracy.
His rivalry with Zentradi ace Milia Fallyna culminated in three victories: first in mecha combat, then an arcade simulation, and finally a knife duel. Sparing her life, he proposed. Their televised 2010 wedding, officiated by Captain Global, marked the first human-Zentradi union and became a catalyst for peace. Post-war, they settled near the SDF-1 Macross, welcoming their first daughter, Komilia Maria Fallyna Jenius, in March 2011. The name "Komilia" (Little Milia) reflected her resemblance to her mother. Max proved a capable, though occasionally exasperated, father, especially when Komilia played with his hair. The family strategically aided in capturing a Zentradi factory satellite in November 2011 by presenting Komilia; the Zentradi, unfamiliar with infants, fled in terror, causing disarray.
Between 2011 and 2031, Max and Milia had seven biological daughters—Komilia, Miracle, Muse, Therese, Emilia, Miranda, and Mylene Flare Jenius—and adopted a Zentradi girl, Moaramia Fallyna Jenius. By 2045, Max commanded the Macross 7 fleet as captain of the Battle 7, advised by Exsedol Folmo. His marriage to Milia had dissolved, but they maintained professional contact due to her role as mayor of City 7. Only their youngest daughter, Mylene, remained with the fleet. Max initially forbade Mylene from joining Sound Force over safety concerns but relented after witnessing her piloting and musical skills. He frequently clashed with Milia over Mylene’s involvement yet collaborated with her during the Protodeviln crisis, piloting his signature blue VF-22 Sturmvogel II alongside Milia’s red unit to save the fleet, leading to a temporary reconciliation.
Post-2045, Max founded the flight school "Jenius Air" while on active duty, inspiring his granddaughter Mirage Farina Jenius to become a pilot. By 2067, his legacy exemplified resolving conflict through mutual understanding. Later, he served as captain of the Macross Gigasion, aiding the Delta Flight squadron and Walkure idols.
Noted for his blue hair and glasses, Max aged minimally, attributed to his "genius" mindset. His abilities included a "genius intuition" for predicting enemy tactics, culinary expertise with a vast recipe repertoire, and sustained piloting proficiency into old age, evidenced by mastering advanced fighters like the YF-29. Alternate depictions exist, such as in the film *Do You Remember Love?*, where he met Milia during a battle resulting in Hayao Kakizaki’s death and briefly led the Skull Squadron after Roy Focker’s demise.
