Last night, I downloaded the dual-type Bug/Steel type legendary Pokemon called Genesect for my copy of Pokemon White 2. It's a crazy looking robotic bug with a mounted cannon--and very powerful to boot, even at its base level of 15. Anyways, after every victory with it, a message says it gained "boosted" EXP, earning a little more than any other 'mon would. I'm not sure why this is happening, unless it has something to do with its nature. It also seems to vary drastically based on who it is fighting and for how long. Is this something I can teach other Pokemon in my team or is it just super special?
