Battle of the Century! Or Something!
While I've found nothing to suggest that Black Lio Convoy is and evil version of the original, it is almost inevitable that a Western release of this model would have been rebranded Nemesis Prime, and given dark red eyes. Assuming this to be the case, here's a comparison/face-off between the two...

Lio Convoy: "Give me your best shot, evil one!"
Black LC: *snikt*

Thanks to the intricate system of joints, Lio Convoy is quite a posable
figure.
The only real drawback is that his hips don't allow a huge range of
motion,
and the lion parts on the shoulders, while dramatic to look at, hinder
the movement
of the arms to some degree. The right shoulder is hit hardest.

Normally the black/grey/metallic turquoise would be applied to a
Nemesis version,
but they tend to have either red or black eyes, whereas Black Lio
Convoy has blue eyes.

In many ways, the original's lion mode looks far better - a black lion
somehow doesn't quite
look right. I'm very fond of this model and black repaints, though, so
I think this one is
pretty cool. I don't hink I'll be getting Flash Lio Convoy, however. A
translucent/glittery
lion just doesn't work for me!
