well, it dipends on your fighting stile. If you like balanced stats chose TURWIG. If attack and speed is what you want Chimchar is the top contender. But with all but special defense with him piplup is my favorite and strongest Pokemon of the three starters.
I also like piplup but, It is easier to go through the game with a Vaporeon, or a Gyarados.
I would use Electivire, Roserade, Gastrodon, Infernape, Gallade, and Gachomp. That's the team i use and I haven't been beaten yet
There's not the strongest, but the are strong teams.
Your team Should have:
1.1-2 sweepers Like Infernape, Alakazam and Lucario
2.1-2 Walls like Blissey, Shuckle and Milotic
3.1 Good starter Pokemon (Pokemon in first slot) like Shuckle.
4.0-1 Rabid spinner like blastoise
5. Try have at Least 1 Fire, 1Water and 1 Grass type Pokemon in team
6. 1 healer like miltank
7. 1 staller/annoyer like crobat and azumarill
Avoid using same item twice in team!
Dont use these Pokemon in WiFi battles:
Mewtwo
Mew
Wobbuffet
Lugia
Ho-Oh
Latios
Kyogre
Groudon
Rayquaza
Deoxys (all forms)
Dialga
Palkia
Giratina
Manaphy
Darkrai
Arceus
Shaymin-S
Garchomp
It all depends on your team line up. It could be Dialga, Palkia, Giratina, or Arceus.
turtwig is because its good against the first gym leader
Pick him as your starter
Technically Cyndiquil is the strongest but it all depends on what type of Pokemon you want.
The easyest Pokemon is scizer and the hardest Pokemon is milotic.
still the same Pokemon as d/p chimchar, piplup, and turtwig
arceus is i said party not single pokemon.
The rival's starter gets up to level 85
Giratina
in my opinion, torchic or mudkip is the strongest.
starter Pokemon
Chimchar, piplup, and turtwig.
Tortera because is the only starter Pokemon that can learn earthquake witch is powerful.
Pick him as your starter
Piplup
It is a completely a opinion
You can get another starter if you get all the sinnoh pokemon. Proffeser rowan will ofer a johto starter.
There isn't one.You can train well,and any Pokemon can be the strongest.But there really is not a strongest Pokemon.
Pikachu has the most experience in battles and is the strongest starter Ash has.
