Shank is one of the Daluma Guild's most feared members—and honestly, the terror he personally inflicts on the galaxy might outweigh what the entire organization manages. He's bloodthirsty, sadistic, and brutal enough that both the Galaxy Police and his own peers keep their distance. As captain of the Daidalos, he has a reputation for leaving no survivors. That said, for all his cruelty, Shank is ultimately a coward at heart: he'll torture someone for hours to maximize fear, but the moment things go wrong, he's quick to use his own crew as shields and cut and run.
His vendetta against GP officer Seina Yamada starts before they ever meet. Some ancestor of Seina's broke and imprisoned one of Shank's relatives, and that shame has eaten at him ever since. When he finally encounters the "incompetent kid," he can't resist. Shank attacks a destroyer carrying Seina and stalks him for the thrill of the hunt, casually murdering GP officers along the way. The fun ends when Kiriko Masaki shows up to rescue Seina, giving the boy just enough time to stab Shank in the arm and escape. It's a humiliation Shank vows to repay in blood.
His attempts to take Seina's family hostage fall apart, and a direct confrontation with Seina's fleet near Jurai forces him to retreat. But Shank doesn't stay down for long. He orchestrates a massive infiltration: his crew slaughters everyone on a commuter ship, leaving behind a bio-droid as the "sole survivor" that Seina's ship, the Kamidake II, recovers. It works—the K2 gets captured and swallowed by the Daidalos. Shank is savoring the moment, even returning Seina's own knife to him through the chest. Except it's all a trap. Washu had replaced the real prisoners with dupes, and from inside the Daidalos' docking bay, the K2 tears the massive ship apart from within. Shank survives, but barely—the upper left half of his face and torso are permanently scarred and replaced with metal augmentations. It's a loss that costs him his shot at commanding the Daluma's newest flagship.
When the Daluma Guild dissolves and gets absorbed into the Balta Guild, Shank isn't around to see it. Instead, he teams up with a rogue faction of the Galaxy Army. Together they kidnap Fuku and the Kamidake II, hoping to reverse-engineer the ship's technology. Shank grows impatient with his scientists' slow progress and jumps at the chance to finally fight Seina again—but he's caught completely off-guard by Seina's rage and ends up fleeing for his life as the young officer's mecha nearly crushes him.
Not finished yet, Shank commands a rebuilt Daidalos and coordinates his fleet with the rogue GA ships for one final, massive assault on Seina. They aim to kill him and incinerate his homeworld to cover their tracks. The mecha doesn't fall though. Instead it teleports in front of both fleets and keeps coming. Panicked, Shank throws his own ships and crew into the fire as cannon fodder and orders a hyperspace jump. The Daidalos warps away just as the mecha reaches for him—but then something impossible happens. The mecha's hand, powered by Light Hawk Wings from a Juraian tree seed, stretches into hyperspace itself and yanks the Daidalos back out. The ship implodes under the force, and Shank vanishes with it.
Except he doesn't stay dead. Shank shows up one last time on Seina's wedding day, dressed as a butler, half-crazed from cybernetic modifications and purely focused on revenge. He moves to slash Seina with his knife, already promising to kill Kiriko next. The attack damages the floor and triggers sealant gel that locks him in place. When Seina kicks his metallic leg hard enough to snap it off, the sparks trigger the ship's automated defense systems. The sealant floods around him, immobilizing him completely no matter how loud he screams or how much he curses. Shank finally gets what's coming to him, trapped and helpless.
