Question: What two persons created the fictional anti-hero who appears in the Marvel Comics and is the sone of Romani witch Cynthia VonDoom?
Context: Scarlet Witch is a fictional superheroine appearing in American comic books published by Marvel Comics.  The character first appeared in "X-Men" #4 (March 1964) and was created by Stan Lee and Jack Kirby.  The character has since starred in two self-titled limited series with husband the Vision, and has historically been depicted as a regular team member in superhero title "The Avengers".  She has numerous alternative versions throughout the Marvel Comics multiverse. Cipher (Jennifer Swann) is a fictional character appearing in American comic books published by Marvel Comics.  The character appears in the newuniversal imprint of Marvel Comics, and is one of the four initial superhumans created by the White Event in 2006 (the others being Justice, Nightmask, and Star Brand).  "newuniversal", designated Earth-555 in the Marvel Comics multiverse, is a re-imagining of the New Universe imprint from the late 1980s.  The name Cipher actually refers to two things: a powerful extra-dimensional glyph (tattoo) that confers superhuman powers on a sentient being, and the name of the being that wields the glyph.  Cipher is a new superhuman created by Warren Ellis and Salvador Larroca who were inspired by the original Spitfire and the nature of the Star Brand itself (as an extra-dimensional tool of near-unlimited power), combined with strong conceptual ties to Iron Man. Namor the Sub-Mariner ( ) (Namor McKenzie) is a fictional character appearing in American comic books published by Marvel Comics.  Debuting in early 1939, the character was created by writer-artist Bill Everett for Funnies Inc., one of the first "packagers" in the early days of comic books that supplied comics on demand to publishers looking to enter the new medium.  Initially created for the unreleased comic "Motion Picture Funnies Weekly", the Sub-Mariner first appeared publicly in "Marvel Comics" #1 (cover-dated Oct. 1939) – the first comic book from Timely Comics, the 1930s–1940s predecessor of the company Marvel Comics.  During that period, known to historians and fans as the Golden Age of Comic Books, the Sub-Mariner was one of Timely's top three characters, along with Captain America and the original Human Torch.  Everett said the character's name was inspired by Samuel Taylor Coleridge's poem, "The Rime of the Ancient Mariner".  Everett came up with "Namor" by writing down noble sounding names backwards and thought Roman/Namor looked the best. Hybrid (real name Scott Washington) is a fictional anti-hero appearing in American comic books published by Marvel Comics.  Scott Washington first appeared in "The New Warriors" #21 (March 1992) by writer Fabian Nicieza and penciller Mark Bagley.  The symbiote first appeared in the back-up stories in the "Venom: Along Came A Spider" (1996) miniseries by writer Evan Skolnick and penciller Patrick Zircher. Doctor Victor Von Doom (or simply Doctor Doom) is a fictional supervillain appearing in American comic books published by Marvel Comics.  The son of Romani witch Cynthia Von Doom, Doctor Doom traditionally has been the archenemy of the Fantastic Four, and the leader of the fictional nation of Latveria.  He is both a genius inventor and a sorcerer.  While his chief opponents have been the Fantastic Four, he has also come into conflict with Iron Man, Spider-Man, Black Panther, the Avengers and multiple others.  Doom has been depicted as a superhero, taking up the mantle of Iron Man from Tony Stark, and going on to join the Avengers. Captain America is a fictional character appearing in American comic books published by Marvel Comics.  Created by cartoonists Joe Simon and Jack Kirby, the character first appeared in "Captain America Comics" #1 (cover dated March 1941) from Timely Comics, a predecessor of Marvel Comics.  Captain America was designed as a patriotic supersoldier who often fought the Axis powers of World War II and was Timely Comics' most popular character during the wartime period.  The popularity of superheroes waned following the war and the "Captain America" comic book was discontinued in 1950, with a short-lived revival in 1953.  Since Marvel Comics revived the character in 1964, Captain America has remained in publication. Bleez is a fictional anti-hero and supervillain appearing in American comic books published by DC Comics.  Created by writer Geoff Johns and artist Shane Davis, the character first appears in "Final Crisis: Rage of the Red Lanterns" #1 (December 2008). Symkaria is a fictional Eastern European country appearing in American comic books published by Marvel Comics.  The country was created by Tom DeFalco for the Marvel Universe.  It is one of several fictional countries in Eastern Europe created for Marvel Comics.

The country has appeared in issues of "Silver Sable", "Silver Sable and the Wild Pack", "The Amazing Spider-Man", "Thunderbolts", "Citizen V and the V-Battalion", and other comics published by Marvel Comics.
