Empoleon if your starter was Piplup, but if not...
A gyarados. (catch a magikarp)
A golduck.
Floatzle (if your going for an all sinnoh team)
Azumaril
Mantine
Milotic
And Palkia is part water :\
An east sea gastrodon is the best disunion i ever made.
go on Google:Web type in Pokemon platinum. when you are on it, put your DS on, ask a parent to do this.
The last person of the Elite Four in Pokemon Platinum is Lucian, the master of Psychic-type Pokemon. After him is Cynthia, the Champion.
electric is good against water type
Luminion. It can be found in canalave city with a good rod or super rod
Mudkip is a Water type pokemon.
in Pokemon platinum if you have a water type Pokemon go to the tutor men in pastoria city
Magnezone.
Milotic. Enough said
Pokemon 170 is Chinchou. It's a Water/Electric type and It's very good. On route 220 use surf then use a super rod.
You can use a good dark type pokemon like umbreon,hoondoom etc. I hope this help!! :-)
sentret and furret.
No! Do you mean to have a electric type pokemon? There's lots of good electric type. I would prefer Luxray or Magnezone.
you should use water type Pokemon
practically any water type. All the water starters can learn surf, palkia can too!
the 8th leader in platinum uses electric type so i would recommend using ground type Pokemon..............if you don't have ground type Pokemon don't worry he isn't that good
You can use a water type pokemon because it is really effective on rock type pokemons.•Make sure your pokemons are leveled up toabout level 20.GOOD LUCK!! ;)
Magmar, Monferno, Moltres and Infernape are good fire-types.
