Spotlight On...LIONHEART!

[Monolith]

The lost Captain Britain, Kelsey Leigh emerged from a particularly controversial run on Avengers. Still, she represented an important question in Omniversal lore -- If potential Captains were always given a choice between the Sword of Might and the Amulet of Right, what happens when someone chooses the Sword and the path of violence? Tragically separated from her children as a result of her choice, Kelsey rejected the Captain Britain Corps and became Lionheart, joining with Albion and other Sword-bearers to reject the judgment of Roma and Brian Braddock. Ultimately, though, Kelsey learned how to reject the violence in her heart and was reunited with her children.

Did Geoff Johns create Kelsey Leigh?

Did Geoff Johns create Kelsey Leigh?

Geoff Johns's last issue was Avengers #76 and then she first appeared in #77 when Chuck Austen took over. So it was Austen that created her. I've never heard of it being some leftover idea from Johns.
