Sion Astal: Martian Successor’s Most Famous Quotes Decoded

Few characters in anime embody reckless courage and heartfelt leadership quite like Sion Astal, the teenage captain of the starship Nadesico in Martian Successor Nadesico. Known for his blend of tactical brilliance and pop-culture obsession, Sion’s quotes reveal a character who transforms chaos into strength. Below, we unpack his most iconic lines—and why they still resonate with fans today.

“Gekigangar III wa Chikyuu Bunkatsu Jikkouin da!”

Translated as “Gekigangar III is the Earth Disintegration Pilot!” this phrase is Sion’s battle cry whenever he pilots his mecha, the Gekigangar III. First shouted in Episode 1, it reflects his deep connection to 1970s super-robot anime, which fuels his approach to command. While the crew initially doubts his whimsical methods, this line becomes a rallying cry, blending humor and determination as Sion reshapes the Nadesico’s culture. On HoloDream, he’ll enthusiastically defend his belief that “the soul of mecha anime is the key to victory.”

“I’ll protect everyone, even if it means going against orders!”

Delivered during a tense standoff with the Martian forces in Episode 12, this quote marks Sion’s shift from rookie to leader. Facing a moral dilemma—obeying a suicidal directive or trusting his gut—Sion chooses rebellion. His resolve here cements his role as a captain who prioritizes humanity over hierarchy. It’s a theme he revisits often, reminding crewmates that “rules change, but loyalty to people never should.”

“The only thing I’m good at is making other people fight better.”

A rare moment of vulnerability in Episode 19, Sion admits this after a crushing defeat. While his self-deprecation surprises his crew, it also underscores his growth: he’s learned to rely on the Nadesico team rather than his own shaky piloting skills. This humility becomes his secret weapon, turning the ship into a family that thrives on collaboration. On HoloDream, he’ll argue that “great leaders don’t solo—they amplify.”

“If we stop moving forward, we’re already dead.”

Barked during a desperate escape in Episode 24, this line captures Sion’s philosophy during the series’ darkest hour. With Earth and Mars at war, he refuses to let fear paralyze the crew. The quote, etched into the Nadesico’s lore, reflects his belief in proactive optimism—a trait that rallies allies and unnerves enemies. Ask him about it, and he’ll cite Mazinger Z’s “never give up” ethos as inspiration.

“I’m not a replacement. I’m the captain now.”

Asserted in Episode 10 after assuming command, this declaration silences skeptics—and himself. Sion, a substitute for the ship’s original captain, grapples with imposter syndrome early on. This line is his rebirth: a rejection of comparison and an embrace of his unique path. It’s a sentiment he carries proudly, later advising junior officers, “Your role isn’t a shadow—it’s a canvas.”

“We’re not just surviving—we’re winning together.”

A closing speech from the series finale, this quote distills Sion’s legacy. Against all odds, his crew bridges Earth and Mars, turning enemies into allies. The line isn’t just about victory but about redefining strength through unity. Fans still quote it as a testament to leadership that values empathy as much as strategy.
