Here are my updated incarnations of Solitaire (Elaine King) from 4th Edition Champions and Solitaire (Shannon Havelock) from Champions: The New Millennium for 6th Edition. They are what I considered "experienced" versions of the character, as the original stats were "rookie" versions, with an updated design for each.
Included are the Hero Designer files, Adobe PDF, and Microsoft Word versions in case you want to tailor make some changes for your campaign.
Solitaire (Elaine King) - 425 points
Solitaire (Shannon Havelock) - 475 points
