And because you can't have Optimus Prime without Megatron.... I present Megatron from the short-lived line of die cast Omron prizes. In the box first. Front: Side: Back: Other side: Top: Once again, the bottom is just solid red, so no pic. Similar to the die-cast Omron Optimus Prime, Megatron is cast in solid metal. However, Megatron stands slightly taller than Prime at 3.5 inches. Also, while Prime has a golden color to him, Megatron is silver. I've borrowed the following description from the entry for Omron Starscream. Omron Entertainment (a child company of Omron Corporation until it was sold off and changed the name to Furyu in 2007) released a series of gaming arcade prize figures and merchandise in 2003. Even though there was a nation-wide TV commercial for the figures, the distribution was bad and not many gaming arcades actually carried these figures.
Megatron (Micron Legend, Omron, Diecast) - Japanese Transformers - TFW2005 Entry added, thank you for the contribution
Just an added bit of trivia..... I got out a kitchen scale and weighed Megatron. For being only 3.5 inches tall, he comes in at a hefty 13 ounces!
