Chameleon

Chameleon is a primary antagonist in the LCU.

Origin
He was a failed experiment to recreate Jeff Stupido's DNA.

Now
He recruited Emil Blonsky to his perfection program. He then contacted the Joker and made him make a team of villains as a front for his operation. However most of the villains were killed in the process and Chameleon was the only one to escape.

He was questioned by Blonsky to ask if the program will help him get revenge. He responded with: "Yes, Mr. Blonsky it will".

They broke into Bruce Wayne's house and stole Kryptonite from him. Afterwards he kidnapped his maker, Dr. Ian Brown. Later Turretman who was working for him talked to Chameleon about how strange his client was but Chameleon payed no attention to this.

In his lab Chameleon ended up experimenting on kidnapped test subjects though he failed every time
