It! The Living Colossus

Constructed in Moscow by sculptor Boris Petrovski as a protest monument against the oppressive Soviet government, the colossal stone humanoid (originally 100 feet tall) became animate in Marvel Comics continuity when its body was inhabited by the transferred mind of a stranded alien of the Kigor race. Subsequent narrative arcs feature other instances of mind-transfer (notably Bob O'Bryan, a Hollywood special-effects designer), external control by antagonists (Doctor Vault, Lotus Newmark), destruction and later reconstructions (including reduction in size by Doctor Vault and rebuilding as a robot for film use).

The core depiction is a monumental stone humanoid statue approximately 100 feet in height, described as a constructed colossus by sculptor Boris Petrovski. Variations across stories include a later reduced form (30 feet after tampering by Doctor Vault), a rebuilt robotic facsimile used as a film prop, and periodic reconstitutions whose visual specifics vary by storyline; nevertheless the recurring visual motif is a humanoid, colossal constructed figure of stone or mechanical reproduction.

Its abilities derive from its colossal constructed body combined with the intentions of the inhabiting or controlling intelligence: immense physical strength, durability, and capacity for large-scale movement and combat (rampage through Moscow; attacks on U.S. Army forces; battles with superheroes and monsters such as the Hulk and encounters involving Doctor Doom). The Colossus itself does not originate independent sentience in the cited accounts—its actions reflect the aims of the Kigor alien, Bob O'Bryan, or other controllers—and narrative countermeasures center on severing or reversing the animating mind-transfer, defeating the controlling intelligence, or destroying/dismantling the construct.
