Now Koffing is one that I like a little bit, but it doesn't really bring joy to me overall when I see it. Mainly the lack of joy I have is with the design of Koffing, it isn't horrible, but it's just not something that appeals to myself. Then battle-wise, Koffing isn't overly strong physically, but it can have good bulk I feel if used right which isn't overly bad. Plus all I remember about Koffing is that it was with Team Rocket.
