I really think this is a cool crossover. I haven't been into GI Joe for a long time. I use to have a few items and the Hiss tank and motorized tank was a few I remember.
What do you think of this Megatron crossover?
There's this Anti-aircraft Bludgeon GI Joe crossover that I think is just wickedly done. The guy who did that one (Dr. Vile I think?) is one of my favourite crossover customizers.
