Some TMNT stuff really isn't for little kids.

StockGen was a New York City-based scientific research company in the IDW Publishing version of Teenage Mutant Ninja Turtles.


StockGen is a research company owned by Baxter Stockman who is secretly in league with Krang.

It employed many scientists, including Chet Manley and Lindsey Baker as employees and April O'Neil as a college intern. It was the place where various animals were kept who would be secretly mutated, including Splinter, the Turtles, Old Hob, Slash, Wingnut and Screwloose.

After arranging for Splinter to steal a stockpile of mutagen from the company, StockGen was destroyed by Old Hob.

A parallel universe version of StockGen is featured in the miniseries Bebop & Rocksteady Destroy Everything, which is responsible for mutating a time-displaced Rocksteady and Bebop into Bopsteady.
