(Avengers: The Ultron Imperative (fb)) - The Bio-Synthezoids were created by Alkhema using a "Plastoid Birthmatrix" as her third attempt (after the War Toys and Robos) to create a race of synthetic life. However, unbeknownst to her, she was actually following programming from Ultron in building the Bio-Synthezoids. Once created, they set about rebuilding Ultron.

(Avengers: The Ultron Imperative) - Alkhema proudly unveiled her Bio-Synthezoids, but was horrified to learn they had rebuilt Ultron and were under his control. Ultron started a four way war between the Avengers, Bio-Synthezoids, the Robos, and Alkhema's War Toys, as well as Alkhema and Ultron himself. Alkhema was eventually destroyed by Hawkeye with an Antarctic Vibranium (Anti-Metal) arrow, and she destroyed her base and detonated her creations in the process.

Comments: Created by Kurt Busiek, Roy Thomas, Steve Englehart, Pat Olliffe, and Livesay.

Just about every index corrects the spelling of synthezoid to synthozoid, but I'm going with the spelling used in their only appearance.
