Wiccan and the Young Avengers continued fighting crime after the launch of the Superhuman Registration Act, and were arrested by the Initiative's "Cape-Killer" squadrons. Captain America had come out aggressively against the Registration Act, and began forming an underground resistance. He and the Falcon rescued the Young Avengers from their captors, bringing them to one of Nick Fury's safehouses which was being used as the resistance's headquarters. [Civil War (1st series) #2] While the war was raging on, Wiccan and the others made contact with the 
Runaways in Los Angeles, trying to provide support to another underage super-team. The two teams bonded, but the Runaways ultimately decided to remain neutral in the adult super-heroes' war. [Civil War: Young Avengers / Runaways #1-4] During a trap set by Iron Man and the registered forces, Wiccan was rendered unconscious and taken prisoner at the 42 prison in the Negative Zone. He was released along with the rest of the prisoners when Captain America and his "Secret Avengers" took the fight to Iron Man and the battle spilled out over New York. [Civil War (1st series) #3-7]
Despite being well-known to Iron Man, Wiccan and the Young Avengers somehow escaped registration under the act. They still occasionally fought crime in public, avoiding the police and were in touch with the remaining unregistered Avengers who went underground to continue resisting the Act. The Wiccan and Hulkling of Earth-A are known to have vacationed on Earth-616 and joined the Initiative in their names, which may have caused confusion in the official records.

Wiccan and Speed teamed up on a quest to locate the Scarlet Witch and find out the truth about their origins. Their search touched on Genosha and the Transian villages near Mount Wundagore, but proved fruitless. At the New Jersey home where Wanda and Vision once lived and raised their twins, Wiccan and Speed discovered Master Pandemonium lying low. Pandemonium didn't 
approve of his solace being interrupted and banished Speed to his Hell dimension while trading spells with Wiccan. Soon, though, Preston recognized Wiccan's magic as having the same qualities as Wanda's, and ended their fight. Pandemonium was surprised the twins still existed, and told Billy and Tommy everything he knew about his and Mephisto's involvement with their origins. He encouraged the boys to stop looking towards the past and embrace their present. Wiccan and Speed ultimately agreed, and decided to put their search for the Scarlet Witch on hold for now.

The Young Avengers were present in Times Square when an invasion of religiously zealous Skrulls descended on Manhattan. Their scriptures naming Earth as a new Skrull homeland was at odds with the prophecy of the hybrid prince Dorrek VIII becoming the great unifier, and so Hulkling was specifically targeted for execution. Billy worked with the Skrull Xavin of the Runaways to keep Teddy alive, partly hoping he could speak out and end the invasion. Most of the Skrull invaders were too devout to listen to the lost prince, however. Wiccan and the Young Avengers were gathered by Nick Fury and served as part of the final army that defeated the Skrull Queen Veranke and her forces in Central Park.

Tony Stark was cast aside and replaced by Norman Osborn and his Thunderbolts Initiative in the aftermath of S.H.I.E.L.D.'s failures during the invasion. Even under Osborn, the Young Avengers' official status remained undecided. Wiccan and the Young Avengers did have to deal with a copycat group calling themselves "Young Avengers" and questions over what it meant to be a hero or not under Osborn's "dark reign." Although Billy and Teddy initially liked the other team's sorceress, a young Enchantress, her cavalier attitude towards abusing magic and her origin as a creation of Loki led Billy to reject the idea of her joining the group. These Young Avengers soon 
became the Young Masters as Norman Osborn himself exerted influence on the group. [Dark Reign: Young Avengers #1-5] Billy's talent for spell-casting proved skillful enough for Doctor Strange to seek him out. The mantle of Sorcerer Supreme was being passed to a new practitioner by the Vishanti, and Strange considered Wiccan a likely candidate. Although the responsibility ultimately fell on Jericho Drumm, Billy was honored to even be considered for such a high-profile magical role. [New Avengers (1st series) #51-52]
When Stature and Vision started working with a second team of globally active Avengers, they had a surprising teammate in the Scarlet Witch. Stature considered Wanda responsible for her father's death, but she was suspicious of this "Witch" and began to doubt it was really Wanda Maximoff at all. Cassie brought Wiccan and the other Young Avengers to the Infinite Avengers Mansion to confront the Scarlet Witch, trying to work around a spell cast on her by the Witch which prevented her from revealing her concerns. Billy forcibly summoned the Scarlet Witch with his powers once he learned what was going on, and he and Tommy tried to speak with her. In fact, as the Avengers would soon learn, this Scarlet Witch was Loki in disguise and had no interest in the twins' mother issues. [Mighty Avengers (1st series) #28-29]
Norman Osborn finally went too far, using a pretext to launch an all-out assault by the Initiative on Asgard as it floated over Oklahoma. Steve Rogers returned to life as Captain America and led the unregistered Avengers, Young Avengers and Nick Fury's Secret Warriors against Osborn's forces. Billy Kaplan was particularly affected by Asgard's fall. He remembered back to his original codename as Asgardian, and the Norse mythology his father read to him as a child which inspired that love of the myths. When he 
happened upon the Wrecking Crew looting from the treasuries of Asgard during the attack, Wiccan became furious and demonstrated just how powerful his spell casting had become. [Siege #2-4, Siege: Young Avengers #1]
