Mecha-Koopas are, as the name implies, mechanic Koopas, with a wind-up key on their back. They belong to the Super Mario series, and the Koopa Troop. They attack by chasing the player, and, in the manner of Bowser, by spiting fire. If Mario jumps on a Mecha-Koopa, the Mecha-Koopa will be paralyzed, and become a object Mario can throw. He will explode after a short time, like a Bob-omb.
Despite the artificial appearance, this creature longs to be a real Koopa, even going so far as to collapse into a throwable object when jumped on, though its hard metal exterior prevents any real damage and likely would just normally bounce Mario off from it. The Mecha Koopa often sacrifices itself due to its overwhelming desire to be a real creature.
Mecha-Koopas make an appearance on the Koopalings' team in New Super Mario Baseball.
Mecha-Koopas make thier first appearance in a Paper Mario game. They appear as Bowser's minions. HP:4 Attack:1 Defense:0
