On the surface, she battled against Wonder Woman and was defeated. She teamed with the original Villainy Inc. during the 1940s, and then assembled a new version of the team in recent years. Both versions of the team were defeated by Wonder Woman (including one battle when Clea's own daughter, Ptra, helped defeat her mother).
In her last battle against Wonder Woman in Skartaris, Clea was de-evolved and lost.
Clea appears later as part of a large team of super-villains assigned to kill Wonder Woman. She is once again in possession of the Trident of Poseidon and now appears to possess the power of flight. She explains that she, and her fellow cohorts, have had their abilities amplified by the witch Circe. She is eventually subdued by several of Wonder Woman's allies and taken into custody by Nemesis and the Department of Metahuman Affairs.
She also wielded the mystical trident belonging to Poseidon, the Greek god of the oceans.
