List of Marvel Comics characters: 0–9

3-D Man was created by writer Roy Thomas and artist Jim Craig. The character was originally created as a tribute to the unsuccessful Harvey Comics character Captain 3-D. 3-D Man was originally supposed to appear as the back-up feature in a stereoscopic comic book featuring Spider-Man, but the idea was cancelled and 3-D Man made his premiere in Marvel Premiere #35 (1977).^[1] 3-D Man is described as having three times the strength, speed and physicality of an average man.^[2] 3-D Man is the alternate persona of Chuck Chandler, a test pilot who was abducted by the Skrulls. Chandler was imbued with powers by a Skrull artifact during his escape, but the same incident connected him with his brother Hal Chandler, with Hal giving up his energy and going into a coma whenever Chuck needs to access the power of 3-D Man. The character retained his association with the Skrulls, and they became his main adversaries.^[3] The original 3-D Man remained an obscure character.^[2]

The character of Delroy Garrett was created by Kurt Busiek and George Pérez.^[2] Garrett is a former Olympic sprinter who joined a cult, the Triune Understanding, after he was disgraced for using steroids.^[4] Originally known as Triathlon and first appearing in The Avengers #8 (1998),^[4] he is given the powers of 3-D Man by the Triune Understanding after they steal them from Chandler. Triathlon joined the Avengers as the new 3-D Man, but he believed himself to be a token hire as he was African-American and the team was being accused of racism at the time they allowed him to join. The character played a prominent role during the Kang Dynasty story arc, but he was unpopular with readers and was not heavily used.^[2] He played another prominent role in Avengers: The Initiative #19, in which he joins the Skrull Kill Krew and uses his abilities to see through the disguises of shapeshifting Skrulls.^[5] This ability brings him to kill Z'Reg, a defecting Skrull who he falsely believed to be hostile.^[4]

An alternate version of Chandler's 3-D Man portrayed him as a hero in the 1950s who joined that world's version of the Avengers.^[3]

4D Man is a version of Kyle Richmond from Earth X, first appearing in Universe X #0 (2000).^[6] He was cursed by Mephisto to see the future, and he works alongside Isaac Christians, the Gargoyle, to document all of history. This is used as a framing device for 4D Man to be a narrator for the story.^[7] 4D Man is ultimately betrayed by the Gargoyle.^[6]

8-Ball is the name of multiple characters appearing in Marvel Comics.

8-Ball was created by Bob Budiansky and Bret Blevins, and first appeared in Sleepwalker #2 (1991).^[8] 8-Ball has no superhuman powers.^[9] Wearing a spherical helmet designed to look like a billiards 8 ball, he wields a concussive cue stick and exploding balls.^[10] Screen Rant listed him among the worst Marvel Comics villains introduced in the 1990s.^[9]

Jeff Hagees is introduced as a defense contractor and engineer who is also a skilled pool player. He develops problem gambling and adopts the villainous persona of 8-Ball to recoup his losses. 8-Ball first appears as an enemy of Sleepwalker, confronting him alongside 6-Ball, 9-Ball, and 11-Ball. Sleepwalker nearly captures 8-Ball until Rick Sheridan (the human to whom Sleepwalker is bound) wakes up, forcing Sleepwalker to return to Rick's mind. 8-Ball escapes.^[8][9][11]

When 8-Ball and Sleepwalker next meet, 8-Ball proves victorious; he distracts the hero by shooting civilians. He attempts to kill Sleepwalker, who manages to escape.^[12] Later, when Rick and Sleepwalker had switched bodies, 8-Ball and the Hobgoblin each attack Rick, trying to kill Sleepwalker to win a $100,000 bet. The inexperienced Rick is no match for them, which makes 8-Ball realize that Rick is not Sleepwalker.^[13]

8-Ball joins Freezer Burn and Humbug into stealing a chip from Ricadonna's house, during which he is killed by Wrecker. Misty Knight and Colleen Wing later have Ricadonna arrested for orchestrating the hit.^[8][14]

8-Ball is later resurrected by Hood. For a time during the "Devil's Reign" storyline, he is the cellmate of Moon Knight at the Myrmidon, giving him another character to interact with and allowing for character growth.^[15] 8-Ball questions his choices after luring Moon Knight into a trap: unhappy with his identity as a failed supervillain and the assumptions that this creates about him, he changes his mind and goes back to save Moon Knight.^[8][16]

An unnamed character wearing the 8-Ball costume appears in The Amazing Spider-Man #600. He is among the villains who battle Spider-Man and Daredevil at the Bar With No Name. 8-Ball escapes when the police raid the Bar With No Name.^[17]

The third version of 8-Ball is introduced in The Superior Spider-Man #26. Created by Dan Slott, Humberto Ramos, and Victor Olazaba, this version of 8-Ball is recruited by Hobgoblin, who gives him one of Jeff Hagees' old costumes.^[18][19]

During the AXIS storyline, 8-Ball is among the supervillains gathered by Missile Mate to work with the Goblin Nation, claiming that Hobgoblin had abandoned him.^[20] 8-Ball goes on to join Swarm's Sinister Six before eventually returning to Hobgoblin's service.^[21][22]

803 is a service robot who joins Agent Venom (Flash Thompson)'s crew.^[23] He appears in the series Venom: Space Knight, where he plays a sidekick role. The character was created by Robbie Thompson, who described his history as if "C-3PO had stayed with Jabba for thousands of years", saying that this made the character "self effacing" and "somewhat suicidal".^[24] To help Agent Venom move without his legs, 803 builds him a set of prosthetic legs. This idea inspired editor Jake Thomas to focus on the wounded veteran aspect of Thompson's character, including a partnership between Marvel Comics and the Wounded Warrior Project.^[25]
