the best partner is pikachu because many legendary pkmns weak against him.
Pikachu
No, you can be one in explorers of the time, though.
Totodile, with partner of Torchic
Only in Explorers of Time you can be Eevee. I thought you (Hero or Partner) can be Eevee in Explorers of Sky.
you can get him from a partner or leader
get it as your starter or partner. u can also evolve pichu
yes there is
If you have the partner Torchic it will learn mirror move.
you need protect for Bulbasaur and your partner
From What I know I believe you can only get it as a partner or your main character in Pokemon Sky dungeon.
u and your partner both cant evolve until you beet darkrai
there is no "best Pokemon" in eplorers of time/darkness... it all matters on skill
