Fictional character biography
Esteban Corazón de Ablo was a court alchemist in 9th-century Saragossa. Isolated and obsessive, he made a pact with Mephisto, trading his soul for longer life as he sought the secret of immortality. Over the years, his mastery of alchemy advanced to the point where he could break the known laws of science, but it was not enough. Seeking even more power, he relocated his lab to Transylvania in the 19th century and formed an alliance with vampires, hoping to learn the secrets of the supernatural.
This brief starts where responsible research should: with the source description of “Diablo (Marvel Comics)” as fictional character in Marvel Comics. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as fictional character in Marvel Comics. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q1207986. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1964 and 2013.
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.
