Thanks for the suggestions everyone.
Good to know that the Activators Megatron is too delicate for my son at this time.
I guess I'm going to try and track down a McDonalds Megatron first. Hopefully there will be a Canadian eBay seller out there with one.
The Bumper Battlers look like a great idea, any word on a possible Megatron Bumper Battler in the future? I definitely want to get him a Megatron, because right now it's "Megatron this", and "Megatron that" whenever we're at a store with a toy section.
