Chironex uses Number 4: Stealth Kragen's ability to summon two Kragen Spawns, bringing back Stealth Kragen and another Spawn when Quattro uses Giant Grinder's ability again. As the poison continues to worsen Shark's condition, Quattro summons Number 40: Gimmick Puppet of Strings, but it has its abilities blocked by Chironex's trap card. After receiving encouragement from Quattro to stand up, Shark manages to summon Abyss Splash and works together with Quattro to defeat Chironex. This allows Shark and Rio to be cured of the poison, and earns Quattro the Stealth Kragen card. Before disappearing, Chironex remembers that he was responsible for the car accident that killed Shark's family. However, he muses that Shark and Rio shouldn't be here, because he remembered that they were killed in the accident. Afterwards, Shark finds an emblem in his family's mansion, similar to the one he saw in his visions of his past life (the Barian Emblem), implying that he and Rio had died in that accident.
