The variant is on the left.

A variant is any toy in a line that is a different version of another, pre-existing toy in that line. They tend to be rare, and usually include a different accessory or have a different paint job than the original. Again, like chase figures, these can either be a blessing or a curse for a collector. Ask yourself if owning both the blue guy and the red guy is important. Of course, if you're a collector, you've already answered that question.
