Editing Echidna (section)

===Background===
Echidna is the codename of [[Noelle Meinhardt]], a member of the nomadic villain group known as the [[Travelers]], who were dimensionally displaced from [[Earth Aleph]] after being transported into [[Earth Bet]] during the [[The Simurgh|Simurgh]]'s attack on [[Madison]].

Noelle and the rest of her group found and drank several [[Cauldron vial]]s that they found in a briefcase, granting each of them powers. However, Noelle and [[Oliver]] split one of the vials, each of them drinking half. As a result, they received what are believed to be two halves of the same power - Oliver gained a power that adjusted his appearance to the local standard of attractiveness, and Noelle slowly became the monster that would later be known as Echidna.

Noelle was the main cause of the Travelers' nomadic lifestyle due to her occasional rage states and clones that resulted in dozens of deaths. They arrived in [[Brockton Bay]] after fleeing from [[Boston]], enticed by [[Coil]]'s promise to find a way to cure Noelle. Noelle was kept in a secure room underground in Coil's base, far away from other people, but could communicate via a microphone and loudspeaker installed in her room.
