there are no best moves it's just how you use them but i recommend a repeating move for defeating legendarys like bubble beam
Piplup, because Riolu should have the following moves: force palm, focus punch, focus blast and counter. Piplup: bubble, ice beam, bide and vaccum cut. UNBEATABLE!!!!!!!!!!!!!!!!!!
The best team is Shinks and Piplup.
piplup
piplup is the best starter pokermon piplup is the best starter pokermon --------------------------- I chosed Turtwig grass type
Piplup
the best Pokemon to pick at the start is PIPLUP or CHIMCHAR
for a girl what likes cute Pokemon yes, but the best Pokemon is arceus
The best team is the Pokemon that you like the best! Another way is to pick a partner that has attacks that can protect you from your weaknesses. For example turtwig and piplup make a good combination because piplup's water type moves are good against the fire types that are good against turtwig.
Piplup is one of the starter Pokemon you get in Pokemon Mystery Dungeon Explorers of Time. It's male nature is the impish type and the female nature is the quirky type. If you don't have it as your starter or your partner, you get it at Blizzard Island. I'm not sure how to unlock it, but the best way to figure it out is to watch videos and use online walkthroughs. Hope this helped! :3 BTW, in Blizzard Island, Piplup is found on floors 1F-20F. Blizzard island can be unlocked if you talk to sunflora at treasure town after you graduate.
The best Pokemon team in diamond is piplup, shinx, starly, machop, budew, and cranidos
probably turtwig even though it evolves later than piplup and chimchar on its first evolution but it does evolve earlier than them on its final evolution and it has amazing moves and stats
my piplup hasn't fainted ever and i beat the game
