Rick Flag serves as an A.R.G.U.S. operative and field commander of the original Task Force X squad dispatched to a fantasy realm. When his team—Katana, Killer Croc, and Thinker—abandoned him to join the Imperial opposition, he was apprehended by Queen Aldora’s knights and incarcerated. His objective initially centered on harvesting resources for Earth but entangled him in the kingdom’s civil war after Aldora’s forces misidentified the Squad as hostile.

Breaking from stoic archetypes, this iteration portrays him as a comically neurotic leader, branded a "drama queen" for his anxious, inexperienced demeanor. These flaws counterbalance the Squad’s volatility, grounding him as a relatable figure. Yet he retains strategic acumen, brokering a fragile alliance between Aldora’s kingdom and the new Task Force X to combat the Empire. Neither faction fully embraces him, wary of his allegiance to Amanda Waller.

His expertise in nano-bomb deactivation and unique rapport with King Shark—whom he addresses as "Nanaue"—cement his indispensability. Frequently excluded from mission planning by both allies and Aldora, he nonetheless salvages crises through unorthodox tactics and battlefield ingenuity. Past leadership of earlier Suicide Squad units, marked by betrayal and imprisonment, reflects his turbulent history with authority and teammates.

This anime interpretation contrasts prior media depictions, such as the DC Extended Universe’s disciplined colonel overseeing lethal operations until his demise, or comic iterations exploring his military lineage and moral dilemmas. Here, his arc interweaves vulnerability with humor, exemplified by frantic attempts to validate his leadership despite constant skepticism. The result is a figure oscillating between self-doubt and tenacity, diverging from his typically rigid, duty-focused persona.
