Arcanna is a native of the other dimensional alternate earth inhibited by the team of super human champions known as the Squadron Supreme. Arcanna was born with an aptitude of wielding supernatural powers as well as certain psychic powers which developed as she matured. It is not yet been revealed how she learned to master her magical abilities
Arcanna originally worked as a medium but after marrying Philip Jones, she decided to support her family as a professional crime fighter. Her husband stayed home to raise their children.
Arcanna's success as a crimefighter came to the attention of the Squadron Supreme, who made her their fifth recruit.
Like most of the rest of the Squadron, Arcanna was mentally enthralled by the Overmind, a collective alien intelligence working in concert with the demonic entity Null the Living Darkness. The Overmind used the Squadron as his agents in the conquest of the Earth-712. However, the Squadron member Hyperion, who retained his free will, in alliance with superhuman champions from Earth-616 called Defenders, freed the Squadron from the Overminds control. Together the Squadron and the Defenders vanquished the Overmind and Null.
The Squadron's Earth was left in a political and economic ruin in the aftermath of the Overmind's takeover. The Squadron, including Arcanna decided to take control of the United States for a year in order to implement their "Utopia Program", by which they intended to solve all the nation's major problems, ranging from hunger and crime to illness and death itself. During this year Arcanna became pregnant again, but fearing the Squadron would compel her to take less active role if they knew the truth, she kept her pregnancy a secret at first. Later she misled the squadron into thinking she had become pregnant months later than she actually had, using her magical illusion casting powers to conceal the changes in her figure.
Finally, Arcanna went into labor during a battle in Squadrons City, The Squadron's headquarters, between the Squadron and the members of the Redeemers, a team recruited by Nighthawk, a former Squadron member had resigned in opposition to the Squadron's assumption of political power. The Shape, a Squadron member who had joined the Redeemers but still regarded Arcanna as his friend, left the battle to take her to the Squadron Capital Hospital. The Squadron lost the battle, and Hyperion, conceding that Nighthawk had a right to oppose them, surrendered on the Squadron's behalf. The Squadron pledged to give up control of the United States and to help dismantle the Utopia Program.
Meanwhile, at the hospital Arcanna gave birth to her son, Benjamin Thomas Jones. She remains a member of the Squadron Supreme today.
