Source-derived summary

Doctor Spectrum is the name of several fictional characters appearing in American comic books published by Marvel Comics. There have been five versions of the character to date—three supervillains from the mainstream Marvel Universe belonging to the team Squadron Sinister (Earth-616) and two heroes from different alternate universes. The two heroes each belong to a version of the team Squadron Supreme, the Squadron Supreme of Earth-712 and the Squadron Supreme of Earth-31916 respectively). Spectrum is a pastiche of DC's Green Lantern.

Fictional character biography

Squadron Sinister

The first version of the character, Kinji Obatu, appears in The Avengers #69 (Oct. 1969), and is created by Roy Thomas and Sal Buscema. The story arc introduced the supervillain team the Squadron Sinister, created by the Grandmaster to fight the Avengers. The four members were loosely based on heroes in DC Comics' Justice League of America, with Doctor Spectrum based on Green Lantern.

The Grandmaster assembled the Squadron Sinister to battle Kang the Conqueror. Spectrum is defeated when Iron Man deduces that Spectrum's Power Prism (a sentient entity called Krimonn) is vulnerable to ultraviolet light.

Editorial analysis

Why this record matters

The phrase “comics character” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 11, 2026. The linked authority identifier is Q1761283. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1969.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
