Significant storylines for the character include his and his brother's search for their original mother, learning to master his powers, and an ongoing relationship with his teammate (later husband) Hulkling.

4, written by Al Ewing, as a member of an Avengers team led by Sunspot, alongside Hulkling, Songbird, Squirrel Girl, Hawkeye, Power Man and White Tiger.

Soon after, Wiccan became a main character in Strikeforce, also written by Howard, alongside Blade, Angela, Spider-Woman, Monica Rambeau, Daimon Hellstrom and Winter Soldier.

[14] Somehow, years before the marriage of Wanda and Vision, their twins are reborn as Thomas Shepherd (later the hero called Speed) and Billy Kaplan, two boys physically identical (except for hair color) but born to different families.

However, the Runaways believe that the Young Avengers have come to capture them and a fight ensues until Eli Bradley (Patriot) convinces Nico Minoru to stop the hostilities.

This liberation is made possible largely by Teddy's shape-shifting ability, which allows him to mimic Hank Pym's retinal and voice patterns, and thereby release all the prisoners from their cells.

[31][32] Wiccan, a lover of Asgardian mythology, fought in the battle, and alongside Hulkling defeated the Wrecking Crew, who were looting the Throne Room after the fall of Asgard.

The Avengers arrive and take Wiccan to their base stating that they want to examine his full capabilities, concerned that, like the Scarlet Witch, if he were to lose control of his powers, he could cause massive devastation.

In the process, the Avengers reveal to the team that the Scarlet Witch, having had a mental break after losing her twin sons, killed several of her teammates, changed all of reality into House of M, and then was responsible for the depowering and deaths of millions of mutants.

Seeing the Avengers' and his friends' distrust of the Scarlet Witch and their discomfort with him due to uncertainty of his powers, he storms out, only to find that Captain America has informed his parents of what occurred during the early battle.

Wiccan blames himself for everything that has happened, and ends up falling into a depression, but with Hulkling proposing to him the two get back into costume with Hawkeye and Speed (Patriot moved to Arizona) and Captain America makes the team full-fledged Avengers.

The three soon reunite with Kate, who has been having one night stands with Noh-Varr, while joined by America Chavez, a god from another universe with super-strength and the ability to kick holes in reality.

Despite the future avengers preparing to kill Billy, Teddy encourages him to fight and he successfully drives Moridun out of his body, averting the huge amount of death that was to be caused.

[41] When Dark Elves invade Manhattan, Billy is summoned by Loki, who is initially disguised as Kate Bishop, to a drag bar where he attempts to convince him to side with Malekith in the war.

Loki tries to gain Billy's forgiveness for attempting to manipulate him and steal the power of the demiurge when they both served as Young Avengers but he refuses, telling him it is not his place as he was not the only one wronged.

The group is attacked by Daimon Hellstrom and, assuming he is a shapeshifter in disguise, Blade kills him before receiving a phone call from Satana who explains that her brother is with her in Las Vegas and is acting strangely.

[44] Teddy later accepts his heritage and the mantle of "Dorrek VIII" at the cost of leaving Billy, becomes the new ruler of the Kree–Skrull Alliance, upon which he begins preparations to invade Earth for "the final war".

As Human Torch burns the Inhibitor Mask off of Hulkling, Captain Marvel uses the Universal Weapon on the imposter who states that the Pyre's trigger has been activated in the sun and faces his Accuser.

By stating an intent and focusing on the outcome, Wiccan is capable of a variety of feats, including, but not limited to tracking and locating others, illusionary disguises, tearing down force-fields, mass teleportation, concussive blasts, enchantments, astral projection, and telekinetic force beams.

[56] Heinberg stated on the situation in a transcript with fans, "According to Billy's theory, the souls of Wanda's twins inhabited his and Tommy's bodies when they were dispersed from Mephisto.

[67] In the aftermath of The Children's Crusade, Billy falls into a months-long depression, watching from the sidelines as New York is turned into "Spider Island" and the Human Torch is resurrected.

It was important to co-author Oliveira that the one-shot depict the everyday "queer life" that Hulkling lives and to expand on his character, who is often "left on the bench" while "Wiccan is off saving the world".

[68] Oliveira had previously shown the couple having a queer everyday life with Wiccan going to a drag brunch with Loki, with Hulkling largely lounging on the sofa at home, eating cereal from a bowl balanced on Excelsior, his Star Sword.

When Kate suggests 'Wiccan' to Billy in Young Avengers #6, she, like me, was not thinking in terms of the specific religious practice of Wicca, but rather attempting to find a suitable counterpart for the word 'witch.'

[74] Andrew Wheeler of ComicsAlliance wrote, "Something about the sweetness of the love between Hulkling and Wiccan, aka Billy and Teddy, has struck a strong chord with readers looking for a little romance to melt their hearts.

Their recent exploits are depicted in Hulkling and Wiccan Infinity Comic #1 (by writer Josh Trujillo and artists Jodi Nishijima, Matt Milla, and VC's Ariana Maher), in which they even explore a life without the other.

"[76] Eric Diaz of Nerdist stated, "Marvel Comics took a big and necessary step into the 21st century today, as they announced the very first marriage between two LGBTQ superheroes will soon take place in their pages.

Some fans of the couple will surely love it, while some won't — but there's definitely a fun sense of artistry on display, particularly with Jodi Nishijima's art and Matt Milla's dreamy colors.

[86] In a reality where after the Hulk was jettisoned into space and discovered by Annihilus, killing him and taking the Annihilation Wave to Earth; Wiccan appears as one of the few remaining superhumans and a member of Quentin Quire's Exiles.

[91] Billy Maximoff and William Kaplan appear in media set in the Marvel Cinematic Universe (MCU), portrayed by Baylen Bielitz as a five-year-old, Julian Hillard as a ten-year-old, and Joe Locke as a teen.
