Splatter Phoenix is a minor villain in Darkwing Duck, and notably the only recurring villain on the series to be killed off.
A rejected artist known for her pompous speech (in "Paint Misbehavin'," she proclaims herself a "daringly innovative pseudo anti-neo post modern deconstructionist"!), her chief weapon is a brush covered with paint that can allow her to enter paintings, animate them, or even to paint wholly new (and usually surreal-looking) creatures that help her.
Her second (and seemingly final) appearance was in the episode "Paint Misbehavin'," where it was revealed that she, like her creations, is actually painted, possibly by herself. In this episode, she was melted when splashed with turpentine. It is implied by Launchpad that she is actually aware that she herself, along with the entire universe of the TV series, is actually animated/painted by "some higher being."
In spite of Splatter Phoenix's death on the show, the cover to the third issue to Joe Books' Darkwing Duck comic book shows her gloved hand, complete with paintbrush, sticking out of the mob of villains trying to grab Darkwing, suggesting that she will be returning in the new comic.
Phoenix is one of the few characters in the series to die onscreen, the other being Major Synapse.
Phoenix's death is closely similar to the Wicked Witch of the West's in the 1939 film, The Wizard of Oz (The Witch is melted by water; Phoenix is melted by turpentine)
