Believing their teammates in the X-Men to be dead after fierce battle with the Goblin Queen and the demon Sym in Dallas, Shadowcat and Nightcrawler formed a new team. A rescue mission to save Rachel Summers (Phoenix III) from Mojo's synthetic hunters, the Warwolves, lead to joining forces with England's champion Captain Britain and his shape-shifting companion Meggan.
After the rescue, the five adventurers formed a team dedicated to investigating and combating superhuman menaces in Great Britain and continental Europe, as well as to the promotion of mutant-human peaceful coexistence throughout the world as Excalibur.
