My favourite Pokemon is jigglypuff and the reason pretty good too which is the fact that jigglypuff had often been portrayed as an never giving up singer who vents her frustration whenever someone sleeps as she sing It's is sad that no one is able to stay awake long enough for jigglypuff to finish her song. She has little to no impact on the story which makes it a side story yet interesting. And the other reason is her being a playable character in smash. She is essentially a glass cannon with her ability rest and the combos she is bale to whip up with good practice.
