Lord Ballister Blackheart, a knight, has assumed the role of a supervillain in order to expose the nefarious schemes of the kingdom's front organization, The Institute of Law Enforcement. The kingdom's champion is Lord Blackheart's nemesis and former best friend, Sir Ambrose Goldenloin. Blackheart's prickly relationship with Goldenloin further explores the limits of their friendship. Enter the title character, a brash young shapeshifter who doggedly follows Ballister until he agrees to take her on as a sidekick. Nimona's skills as a shapeshifter up the ante in the ongoing rivalry between Ambrose and Ballister.
Despite her anger management issues, the teen becomes Ballister's invaluable ally and together they form an alliance of mutual trust and dependence. Action scenes dominate as Nimona shifts with Hulk-like ferocity from frightful creatures such as a fire-breathing dragon to a docile cat or a timid child.
Dialogue is fresh and witty with an abundance of clever lines. A complementary color palette of Blackheart's muddy browns contrasts with Goldenloin's fresh transparent yellow-greens. Both color schemes highlight Nimona's intense reds. Readers will note subtle visual differences in webcomic images. The print edition includes an exclusive epilogue not available online.
At its core, Nimona is a story of rescue. Each of the main characters rescue allies, friendships, the Kingdom, and ultimately, themselves.
