Nice to hear that you'll be around again!

As for the pokemon, it's apparently an evolution (which tend to be seen less often) from gen V (black/white).  If you didn't play those games that much, you may have just missed it.

Also worth noting is that this is pokemon 542- and the number has only grown since then.  As the number of pokemon grows, the harder it becomes to remember them all, and so it could be that you've seen it, but simply never remembered it (it is a fairly generic leaf pokemon by the look of it).

I remember all of them. 

Ash had a Leavanny which put up a fantastic fight against a Sawk, a fighting type Pokemon from Gen 5.
