A.I.M., or Advanced Idea Mechanics, is a fictional group in the Marvel Universe.

A.I.M. is an organization of brilliant scientists and their hirelings dedicated to the acquisition of power and the overthrow of all governments by technological means. A.I.M. was organized late in World War II by Baron Wolfgang von Strucker to develop advanced weaponry for his subversive organization HYDRA. They were close to developing and attaining nuclear weapons when HYDRA island was invaded by American and Japanese troops. Although HYDRA suffered a major setback, it survived and grew in secret over the following decades.

A.I.M. has created three major implements of deadly potential which stand far above the rest of their accomplishments. The greatest of these was the Cosmic Cube , a device capable of altering reality. A.I.M. did not realize that they had only manufactured the cubical containment device; the real power was an entity accidentally drawn into this dimension. The Cosmic Cube recently evolved into Kubik. The second was the Super-Adaptoid, an android capable of mimicking the appearance and superpowers of other beings. The Super-Adaptoid's powers were made possible by incorporating a sliver of the Cosmic Cube into its form. When Kubik repossessed the sliver after defeating the Adaptoid, the android was rendered inanimate. A.I.M.'s third achievement was the creation of the MODOK (Mobile Organism Designed Only for Killing), an artificially mutated human with an enormous head and psionic abilities. Modok was originally an ordinary AIM scientist who was selected by AIM's leader, the Scientist Supreme, to be the subject of the bionic and genetic experiments that turned him into MODOK. after his transformation, MODOK killed the Scientist Supreme and took control of A.I.M., and later took advantage of the organizational chaos following the destruction of HYDRA Island and the deaths of Baron Strucker and most of HYDRA's leading members to sever A.I.M.'s ties with HYDRA.
