Treecko was the first I saw, but I caught Mudkip first ( . . . when I was looking for a Torchic, haha).
That would be "Aron", which I found just before opening this thread. I opted to catch it, as I like the look of it.
saw a skitty first, but haven’t caught any yet !! (i wanted that skitty. but i didn’t have any pokéballs on me at that time. ;-
