do the personality quiz until it sayz that you're a pickachu.
or get hundreds of action replay codes and be whoever you want from this website: http://www.codejunkies.com.
The answer above has been wrote by some idiot who is just trying to advertise a rubbish website. If you want to be Pikachu, all I know is you need to be the brave type, which means having to answer the questions with the option that sounds best for the brave kind.
What the guy in the middle said is true... you can either be a male brave natured pikachu OR you can be a female hasty natured pikachu... you should check out this website... its not junk it gives you hints on how you can do it.

If you are a boy then; answer all questions as "bravely" as possible to get the brave personality and pikachu, if you are a girl you need to get the quirky personality though im not quite sure how to get that. You could also catch a pikachu and switch out your character after the main storyline if you have already completed it or you are far in and don't want to start over again.
piplup will learn peck at lvl 15
Either Piplup, Torchic, or Chickorita.
Yes, just like darkness and time, you can be Piplup. You have to be a Impish Male or Quirky Female to be one though.
It learns it at level 32. For more info click link below.
The best team is Shinks and Piplup.
Choose it when you just started playing the game.you should know thatYou can also get it from lake verity when you have got your national dex. And you should know that horrorknight.Piplup is one of the starter Pokemon in Pokemon Diamond. Simply start a new game and pick it as your starter Pokemon.
If you mean in Mystery Dungeon: Explorers of Time, Darkness, and Sky, you can play as all Sinnoh starters(If that's what you mean).
i do not have explorers of sky
in explorers of time and darkness: Mudkip, Treecko, Torchic, Squirtle, Charmander, Bulbasaur, Chikorita, Cyndaquil, Totodile, Piplup, Chimchar, Turtwig, Pikachu, Meowth, Munchlax and Skitty. In explorers of sky: all the Pokemon of time and darkness plus Shinx, Vulpix, Eevee, Bidoof and Riolu. P.s Meowth and Munchlax are only partners in sky not as hero
Piplup is only found in Pokemon Mystery Dungeon Explorers of Time and Darkness. It is one of the Pokemon that you can become in the beginging. If you don't get Piplup, it can be found in Crevice Cave(floors 1-10.)
I would suggest a piplup if you are a girl, but if you are a boy, a shinx.
The main difference between Pokemon Explorers of the Sky and Pokemon Explorers of Time is that Explorers of the Sky is an enhanced version of Explorers of Time. Explorers of the Sky includes additional features such as new storylines, characters, dungeons, and Pokemon compared to Explorers of Time.
