Gang tensions continue to ratchet up between the J-Pops and the Cryptids as Whoofy (and his consigliere Li’l Boy) fight The Mountain for what’s left of the uranium trade. Meanwhile, the crooked Dr. Zhang gets a reminder from the Moon Bunnies that she’s late on her drug payments and they stress—in no uncertain terms—that it is not healthy for her to cross them. Powerful inmates return to the prison and threaten to upend the precarious species truce. Also: Severed heads! The Sharkmon of Kaijumax! And… a pep-talk from Satan?

The Creature from Devil’s Creek has finally turned state’s evidence against his tormentor, the mountainous leader of the Cryptids. It seems as if his arrest is about to mark the decline of the gang, but a certain tattooed cryptid supremacist stokes their dormant belief in SPEFIWA—Species Final War—and the whole prison waits for the final match that will ignite the unstable nuclear pile. Also: Geosurgery! Unlikely reality checks! And… a rap musical about our founding fathers?

Under the new leadership of Hellmoth, members of the Cryptid Supremacist gang doggedly seek to uncover the identity of the one who turned state’s evidence, while the Creature from Devil’s Creek comes to understand how hollow the warden’s promise of witness protection really was. The compromised prison physician Dr. Zhang has finally escaped all suspicion for sneaking in contraband uranium, and life for her and her inmate paramour Zonn has gotten much calmer… perhaps too calm. Also: Ethical quandaries! Classic evil spirit banishment! An ill-considered attack! And… “You and me, let’s take a walk.”

KAIJUMAX’s last good drug connect has been gone for a while, and the kaiju inmates are fiending for uranium; enter Zonn, Terror of Nagoya and the doctor he’s got in his… er, pocket to bring the good stuff from a new operation on the moon. Meanwhile, Whoofy, the young mob boss picking up the pieces after his father’s death starts to learn what tough rules must be followed -- and whose appendages must be broken -- to stay in power on the inside. Also: Bullying flashbacks! Terrifying moon bunnies! And… astro-kiestering?

SEASON FINALE! All-Out Gang Attack has erupted in KAIJUMAX prison between the Cryptids and the old-school J-Kaiju and it’s every mon for himself amid flying claws, fire breath, and stomping action. Interspecies alliances are broken! Antediluvian lifespans come to an end! In the chaos, Mechazon and Electrogor put their risky plan to murder the crafty and sociopathic Zonn into action, but there’s just so much that can go wrong. Also: New evolved kaiju powers! Two long-awaited comeuppances! A bloodless squishing! And… a new pet for the Sharkmon?

New Season! New jumping-on point! Ah, KAIJUMAX Prison... that cesspool of corruption in the South Pacific! Tensions among the city-destroying convicts have eased after a month-long lockdown and Electrogor's capture, and now the kaiju gangs have begun vying for power again, all-out-attacking their rivals, trading addictive smog and dioxin, and abusing weaker inmates. The Creature from Devil’s Creek, after a long time as the low mon in the Cryptid hierarchy, stumbles upon some information that makes him think it doesn’t have to be like this. Also: Mind-controlled murders! Pre-smartphone navigation fails! And… some VERY old timey religion?

Ah, KAIJUMAX Prison, that cesspool of corruption in the South Pacific. Stomp once again into this toxic holding facility for giant monsters and get to know its most fearsome—and most pathetic—inmates! A seething undercurrent of species hatred now grips the pound, and the gangs are vying for ultimate control of the uranium trade. The claws and flame-breath come out as a knock-down, tear-out-heart species riot rips across the crater block!
