Karai's Vendetta - April first mentions her, and Karai is distracted by the fact that April has lost her mother as well and April manages to escape. The Kraang Conspiracy - Mrs. O'Neil appears for the first time in an old family photo and Jack Kurtzman revealed the Kraang Hive Mind abducted her before April was born. The Hive Mind wanted for yet unexplained reasons a suitable human host for their plans of conquest for the Earth and finally found it in Mrs. O'Neil. They kidnapped and subjected her to experiments in which her human DNA was mixed with the genetic material of the Kraang. As a result of this engagement April was born half Kraang, half human.
