The belief that she was some sort of monster was also affected by the fact that Meggan's birth took place near an ancient British fortress that was rumoured to be the site of dark magics.

Meggan's family hid her away in their camper, where she watched television incessantly, totally immersing herself in the fantasy of the various British TV shows of the time (such as Gerry Anderson fare, Quatermass, Doctor Who and many more).

Meggan then fought Gatecrasher's Technet alongside Captain Britain, Nightcrawler, Phoenix, and Shadowcat, and with them became a founding member of Excalibur.

[8] A few months after she and Brian helped found Excalibur, Meggan resumed the search for her parents, traveling to Europe with Phoenix (Rachel Summers) tracking a rumor of a "magic creature" hidden in a Gypsy's van.

[volume & issue needed] When Roma stepped down and let Captain Britain become the Omniversal Guardian of the Otherworld, Meggan came to rule beside him as his queen.

Working with Princess Royal Elizabeth Glorianna Braddock and Rachel Summers, Meggan and Captain Britain located the hole in reality through which the tidal chaos wave was about to spread.

Allowing the others to seal the gap, Meggan ventured into the void beyond and sacrificed herself to briefly slow the progress of the impacting chaotic energies to give Betsy, Rachel, and Captain Britain time to sew the reality tear.

[13] When reality was restored, only a few remembered what had occurred during the House of M. Captain Britain and the others were among the many who didn't, having only vague memories of the ordeal and believing it to be a dream.

[14] After Pete Wisdom releases the dark and evil magic to prevent the Skrull invasion in England, Plokta, a duke of Hell, tries to make a deal with Captain Britain and reveals what appears to be Meggan in his collection of otherworldly realms.

[15] Captain Britain, knowing it might be merely an illusion, states that he can't take the chance of it being real and plunges through the dimensional gate.

After a while she forms a kingdom, "Elysium", to serve as a sanctuary for souls to escape torment, and gives Pluto part of her conquests in payment.

[20] During the "Infinity" storyline, Meggan represented the Braddock Academy when Henry Pym planned a "Contest of Champions" event.

Meggan's empathy enables her to sense the emotions and feelings of living creatures (from people, to animals, to plants), and including the ability to psionically perceive an object's or person's psychic, natural, and mystical energy aura.

Primarily when she herself was either in a vulnerable emotional state, distracted, focused on the person in question or her powers were in a minor flux from lack of mystical sustenance.

Through thought alone, Meggan can extinguish forest fires, summon gale-force winds, and part the waters of a lake or cause earthquakes in a flash of anger[citation needed].

By combining her powers with Rachel Summers on an alternate Earth filled with magic, Meggan succeeded in bringing the dead back to life.

It was not until she began adventuring with Captain Britain and working with psychic Alison Double[volume & issue needed] that she came to understand the extent of her powers.

It took several more years for Meggan to discover her natural form: taller than a normal human, with longer platinum blond hair, pointed ears, and black eyes.

Her elemental powers also cause Meggan to change in response to her surroundings, growing fur in extreme cold, or gills when she is submerged or swimming underwater.

She can increase the density of her muscle tissue to boost her strength and/or speed to superhuman levels, shown capable of exceeding that of Captain Britain on two separate occasions.

[29] Meggan's most formidable talent is her ability to instantly mimic the powers of other superhumans, in one case turning into fully empowered duplicates of Dazzler, Rogue, Colossus, Longshot, Storm, Wolverine, Rachel Summers, and Havok in rapid succession.

She has no formal education and is self-taught about contemporary culture through television viewing, although her allies from Excalibur take the time to bring her 'up to speed'.

[35][36] On Earth-99746, a world populated by humanoid dinosaurs,[37] the Excalibur-equivalent contains an alternate version of Meggan called Megon who helps defeat the Fantastic Five before traveling to Earth-616.
