+1 Counter vote, while Pikachu is the worst out of the top tiers he is still top tier. I don't believe anybody in this tier deserves to go down, as all of them are pretty clearly better than the Tier 2 kids (+Ryu and Fox who aren't classified as kids lol). Pikachu's Quick Attack is great recovery and extremely difficult to gimp, Pikachu has no trouble racking up damage and little trouble killing, unlike Sheik. While ESAM is kind of the only really well known Pikachu, the only ZSS I can recall from the top of my head is Nairo and people aren't voting ZSS down as much as Pikachu.
Also, Pikachu is blonde. Instant S-Tier (unless your name is Peach, Shulk, Lucas or Toon Link).
