Snorlax is a pokemon from the original 150. He's pretty memorable, mostly for being a huge obese and sleepy pokemon. He did pack quite a physical punch though. I mainly remember him for blocking my path and being glad I found the pokeflute to wake him up.
I also liked his appearance as a pokeball item in the Super Smash Bros series. If you see him pop out of the pokeball, it's time to run. Snorlax has helped me get many KOs from friends to computer opponents.
His Japanese name is カビゴン(Kabigon) which may be a combination of 寐 (Bi) which means "sleeping soundly" and 鼾酔 (Kansui) which means "snoring".
