Mega Man 6 countries question

[edify]

Hey, folks:

As we all know the robots from Mega Man 6 were all created by inventors from around the world. My question is what countries are the robot masters from? I think I have seven of them. If I'm wrong, by all means let me know. But the seven I have are:

Tomahawk Man (United States)
Yamato Man (Japan)
Knight Man (England)
Centaur Man (Greece)
Wind Man (China)
Flame Man (India)
Blizzard Man (Canada)

And the one I'm missing is Plant Man. So if you know which country he's from, I'd love to know. Also, if I'm wrong on any of the others, feel free to correct me.
