OSR Deadly NPC - The MOLCOS (Maintenance Of Law Cybernetic Organism Suit) From Yoshiaki Kawajiri's 1990 cyberpunk OVA Cyber City Oedo 808 For The Cepheus Engine rpg

The MOLCOS (Maintenance Of Law Cybernetic Organism Suit) appears in Case 02 (Psychic Trooper) of Yoshiaki Kawajiri's 1990 cyberpunk OVA Cyber City Oedo 808. Designed by the military as a ruthless heavy-assault cyborg law enforcement suit, it consists of a recently deceased subject’s amputated torso and brain housed inside a massive armored frame. Chemical brain stimulation unleashes latent telekinetic abilities alongside its physical firepower.

Below are stats and mechanics designed for the Cepheus Engine (and compatible 2D6 sci-fi RPGs).

Special Capabilities & Weaponry

• Extendable Hydraulic Limbs: Its arms and legs can extend up to 15 meters on multi-jointed hydraulic shafts, allowing it to scale vertical surfaces or deliver crushing melee strikes at long reach.

  • Telescoping Hydraulic Claw: Reach 15 m, Attack Skill: Melee (Unarmed) 3, Damage: 4D+3 Crushing.

• Telekinetic Blast: The brain core is chemically overdriven to unleash directed kinetic shockwaves.

  • TK Shockwave: Range: 30 m, Attack Skill: Psi (Telekinesis) 3, Damage: 5D Energy/Force. Hits all targets in a 3-meter radius from the point of impact. Ignores soft personal armor (applies full damage unless the target is wearing powered/hard vehicle armor).

• Deflective TK Barrier: Can spend a minor action to create a telekinetic shield. Adds +6 to its Armor against incoming physical projectiles and energy fire for 1 round.

• Thermal Immunity: Internal self-cooling units make MOLCOS completely immune to environmental heat up to 100°C (200°F) and resistant to flame-based attacks.

Weakness & Malfunction: Resonant Audio Susceptibility

Because the subject's brain is held in an extreme, chemically stimulated near-death state, high-frequency metal-on-metal vibrations and extreme sonic feedback directly disrupt its neural stabilization core.

• Acoustic Feedback Trap: If a character intentionally generates heavy sonic distortion (such as striking steel girders or playing back high-decibel resonant sound near MOLCOS):

  • MOLCOS must make an END check (DM-2) or become Stunned for 1D rounds.

  • While stunned, its TK Barrier fails, and all attack rolls against MOLCOS receive a +2 DM bonus.
