Megaplex
From Multiversal Omnipedia
Megaplex was a duplicate of Decepticon leader Megatron, used to trick Autobots who seek to destroy the real thing. Megaplex, despite being a copy, is a formidable warrior in his own right.
Comments
The concept of Megaplex was carried over to another toy with the same name- this one being a slightly altered version of the original Megatron toy (an exclusive from the Japanese toyseller E-Hobby) released in 2003.
