Fan Casting Scarlett Beetle in Edgar Wright's Astonishing Ant-Man

The Scarlet Beetle is a product of genetic engineering on a beetle designed to control other insects. The Scarlet Beetle was designed and developed by Dr. Elias Starr as part of a scheme to wrest control of the ants from his scientific rival, Dr. Henry Pym, better known in some circles as Ant-Man. However, the Beetle grew too fast and intelligent for Starr to fully control, and took control of the solitary insects in their native Chicago with the intent of destroying all humans and claiming the world for himself to rule. To defeat his renegade creation, Starr had to make an alliance of convenience with his rival. In the end, the Scarlet Beetle was destroyed. However, the Beetle at the last moment transferred its mind to another beetle, eventually turning the beetle into a duplicate of his original form. Months later, the Beetle reappeared, having formed an alliance with the robotic Ultron, who had similar goals. It took the combined efforts of the Avengers, of whom Ant-Man is a member, to defeat their combined forces. Ultron was seemingly destroyed (he got better), but instead of destroying the Scarlet Beetle, Pym and the Avengers used Ant-Man's Pym particle infused shrinking formula to reduce the Scarlet Beetle to the size of a regular insect and imprisoned him in an insect habitat. During a later confrontation between the Pym and Ultron, the Scarlet Beetle's habitat was cracked open, enabling the Beetle to escape. Where and when the Scarlet Beetle will appear next is unknown.
