One personal Magmatron Easter Egg for me -- when I first got the Japanese BW Neo in 1999, in my review I described his combined beast mode as a "Tri-Dino Fuzor." Then when the Hasbro version of Magmatron came out in 2000, the last line of the tech specs reads,
"Mitotic spark allows for separation into three aggressive dinosaur modes: Landsaur, Seasaur, Skysaur then recombines into an unstoppable tri-dinosaur Fuzor."

That's 1 of 2 times Hasbro's quoted me in a tech specs bio (the other time was in Tripredacus Agent's tech specs - first half of the first line only that they changed "Cybertron" to "Maximal").
So you know for sure that your Magmatron is the Takara version and not the Hasbro version? Cos they're both nearly indistinguishable from each other loose - the best way to tell is from the box. There are some differences with the toys (as noted
here), but in real life they're so slight that it's really, really, really hard to tell even when you're staring at both versions side by side! I nearly went cross-eyed once trying to spot the difference with a side-by-side comparison once. (@_@)
