Giganteki is a colossal, humanoid robot appearing only in the special "Dorami-chan: Mini-Dora SOS". Built by the antagonist Dr. Sewashi, its sole function is the capture of the Mini-Doras. Its name, translating to "Giant Enemy", directly signifies its role. This machine wields immense physical strength, effortlessly lifting and hurling massive objects such as cars and buildings. Jet propulsion units on its back and legs grant it flight capability. Giganteki's primary weapon consists of destructive red energy beams projected from its eyes. Its durable metal body, dominated by red and silver tones, features visible rivets and mechanical joints. Giganteki operates exclusively under Dr. Sewashi's remote control, exhibiting no independent personality, speech, or sentience. It functions purely as a tool for destruction and capture, pursuing its targets relentlessly as directed. While demonstrating considerable resilience, the robot possesses vulnerabilities. Developed solely to fulfill its creator's immediate objective, Giganteki has minimal narrative development. It is ultimately destroyed during the special's climax when Dorami and Doraemon exploit its weakness. The robot possesses no background story beyond its creation for this specific mission by Dr. Sewashi and receives no further elaboration in other Doraemon media.
