Alexis Kerib is an immortal cosmic entity serving as the primary antagonist throughout the Gridman franchise. He maintains a superficially polite and gentlemanly exterior while fundamentally manipulating others, exploiting their negative emotions to sustain himself. This parasitic behavior stems from his eternal existence, driving him to orchestrate cycles of suffering for amusement. Physically, Alexis manifests as a towering figure at 215 cm, predominantly black with a royal blue cloak revealing a red interior. His head features an angular design, a glowing turquoise mouth and visor, silver chains adorning his shoulders, upward-pointed shoulder guards, and gray cords extending from his mouth to his shoulders. His signature power is "Instance Abreaction," enabling him to animate kaiju sculptures into living entities or transform humans into kaiju, exemplified by his conversion of Akane Shinjo into Zegga. Additional abilities include mass resurrection of defeated kaiju, teleportation, energy manipulation, portal generation, attention manipulation to cloak his presence from ordinary humans, and conjuring weapons like swords or spears. He augments these powers by feeding on negative emotions. In *SSSS.Gridman*, Alexis collaborates with Akane Shinjo, a disillusioned teenager unknowingly inhabiting a digital world she created. He nurtures her loneliness and resentment, coaxing her to design kaiju that devastate their city—only to rebuild it repeatedly for his entertainment. When Akane resists creating new kaiju, he resurrects past monsters en masse. After she hesitates to accept Rikka Takarada's friendship, he forcibly transforms Akane into a kaiju to weaponize her despair. During the final battle, Alexis absorbs Akane to evolve into **Giant Alexis Kerib** (75 m, 65,000 t). This form retains his base abilities while gaining immense strength, energy beams, bolts, pulses, flame transformation, and rapid regeneration fueled by Akane's negativity. Gridman defeats him by healing Akane's psyche with the Fixer Beam, severing Alexis's power source. His remains are sealed as a shard by Gridman and the Neon Genesis Junior High Students. In *Gridman Universe*, Alexis resurfaces after multiple dimensions chaotically merge. Akane Shinjo employs "Instance Domination" to fuse with his sealed form, creating **Alexis Kerib (New Order)**—a purple, red, and white variant (59 m, 33,000 t). This form retains Instance Abreaction and regeneration but falters under rapid bodily destruction. Alexis cooperates with Akane to battle the entity Mad Origin, rescuing Gridman and fighting alongside other heroes. When Mad Origin ambushes and consumes him, Alexis expels Akane to safety. Gridman and allies exploit Mad Origin's absorption of Alexis's infinite energy to destroy it. Alexis, severely damaged and discolored, disintegrates into dust after declaring mortality "enjoyable." The Neon Genesis Junior High Students remain skeptical of his permanent demise and vow to reseal him if he returns. Conflicting lore surrounds his origins. One account identifies him as a corrupted future iteration of Over Justice (from *Space Patrol Luluco*) after millennia of multiverse travel, later restored by Gridman's Fixer Beam—though this is alternatively suggested as a mistranslation or voice-actor joke. Another theory proposes Alexis is a demonic manifestation of Over Justice's inner darkness. Design elements, including a sheriff's badge outline on his forehead, support connections to Over Justice.
