Amazo VS Super-Adaptoid

Amazo
First Appearance: The Brave and the Bold #30 (June 1960)
Created: by Gardner Fox and Murphy Anderson

Origin: The android Amazo was created by scientist Professor Ivo, who became obsessed with immortality. The original Justice League of America (Green Lantern, Flash, Aquaman, Wonder Woman, and the Martian Manhunter) discover their powers have been drained and appear to be used in the theft of certain long-lived creatures. Attempting to guard the remainder of the creatures and discover the perpetrator, the League are defeated by Amazo. Ivo reveals he has created a means of extending his life span courtesy of the data obtained from studying the creatures, and almost succeeds in removing the League's memories of their having ever been heroes before being stopped by Green Lantern. The League defeat the android, and store it in their trophy room.

Powers and Abilities: The character in its various incarnations as an advanced android is capable of duplicating the powers of meta-humans, including members of the Justice League (such as the strength of Superman or the speed of the Flash. The androids apparently retain the abilities of the original Justice League of America (Green Lantern, Flash, Aquaman, Wonder Woman, and the Martian Manhunter) and were later written as being capable of simulating other character's weapons, such as the power ring of Green Lantern and the Nth metal mace of Hawkgirl.

Super-Adaptoid
First Appearance:  As the Adaptoid: Tales of Suspense #82 (Oct 1966) then as the Super-Adaptoid: Tales of Suspense #84 (Dec. 1966)
Created: by Stan Lee, Gene Colan, and Jack Kirby

Origin:The Super-Adaptoid debuted in the title Tales of Suspense, being created by scientific organization A.I.M.. The character is an android containing a shard of the artifact known as the Cosmic Cube, and is programmed to defeat the hero Captain America, which it nearly does after infiltrating Avengers Headquarters and copying the standout fighting abilities and respective traits of Captain America and his fellow Avengers (Goliath, Hawkeye, and Wasp). After a long battle between Captain America and the Adaptoid, the Adaptoid flees, incorrectly believing that it killed Captain America

Powers and Abilities: Created by A.I.M, the first Super-Adaptoid is an artificial construct capable of copying or mimicking the powers and skills of numerous super beings, including specific equipment and clothing. This ability to adapt was originally courtesy of a shard of the artifact the Cosmic Cube, although the shard was eventually removed by cosmic entity Kubik. The character, however, has proven capable of continuing to function without the shard. The Adaptoid possesses exceptional artificial intelligence, but limited imagination and an inability to understand the human condition, which has led to defeat in the past. The powers that Super-Adaptoid had duplicated (and has stored in his templates) include Ant-Man II, Atlas, Beast, Black Knight, Captain America, Captain Marvel I, Citizen V, Doctor Druid, Goliath, Hawkeye, Hercules, Human Torch, Invisible Woman, Iron Man, Iron Fist, Luke Cage, MACH-I, Machine Man, Mister Fantastic, Moonstone, Quasar, Quicksilver, Red Skull's battle suit, Scarlet Witch, Songbird, Techno, Thing, Thor, Vision, and Wasp.
