While working at Pleasant Hill, a gated community holding super villains brainwashed by Kobik, Avril runs a daycare center as her cover.

When Baron Helmut Zemo and Fixer regain their memories and start a riot, Kincaid is attacked by the Blood Brothers, but is saved by Captain America and Winter Soldier.

After Captain America shuts down the security system at the Pleasant Hill Museum, Kincaid enters it and encounters the curator, a retired Wendell Vaughn.

[volume & issue needed] At some point they were left in a weapons depot by the alien Kree, where they were discovered by the Uranian Eternals and brought to Earth by the deluded Crusader, who believed himself to be the 1950s Marvel Boy.

[volume & issue needed] Foremost among the bands' powers is the ability to tap into a limitless energy source called the "Quantum Zone".

A Quantum Jump has a destructive side effect on the local environment, violently upheaving gravity and tearing holes in the atmosphere (on Earth, it would damage the ozone layer).

Vaughn initially refrains from using this ability except when in space or in dire circumstances, but eventually discovers that he can prevent this effect by surrounding himself with a barrier of solid energy before jumping.

The maximum obtainable flight speed is unknown, but Vaughn once made a trip from Earth to Uranus in approximately four years flying non-stop (this was before he learned how to quantum jump).

For instance, at one time Vaughn had the Earth surrounded with an invisible lattice-work of energy that was designed to act as a global alert system against potential extraterrestrial threats.

[volume & issue needed] Phyla-Vell discovers that the bands contain a finite amount of energy which will drain away if they are isolated from their power source (as yet unexplained) and that they also remain linked in some way to their former users.
