From Bulbapedia, the community-driven Pokémon encyclopedia.
This page contains party information for my third playthrough of Pokémon Mystery Dungeon: Blue Rescue Team. I accidentally deleted my first save file because I wasn't paying attention to what buttons I was pressing, and intentionally deleted my second for various reasons. Information for those saves can be found here and here. Word of warning, I made those pages a long time ago, they're pretty bad.
All movesets on this page are subject to change to some degree - except Jolteon's, I'm 100% happy with that one. Thundershock/Dragonbreath/Ancientpower are spelled without CamelCase in this game, but I can't use those spellings in the template without creating red links.
Team Potassium
Starter and Partner
Part of the reason I wanted to restart my second save file was to pick Eevee so I could evolve into Jolteon, took me a few tries before I realized I had to lie and pretend I was a girl. Turns out if you tell the game you're female you get these totally pimpin' pink text box frames. Picking male gives you really boring blue ones which is kind of dumb imo, I would've liked to be a boy and at least have the option to have pink frames but I digress.
While I'd picked Squirtle as my partner in my previous two runs, I decided to change things up a bit and try a different Pokémon this time. I ended up choosing Torchic because it seemed like the most difficult to recruit post-game and had the more fun-looking moveset (the other option was Cyndaquil).
Tradition
I'd trained a Blastoise and an Articuno to very high levels in all my playthroughs so far and decided to do it again this time. Fortunately, Squirtle is basically the first recruitable starter Pokémon post-game so I didn't have to catch up with it as much as I might have otherwise.
imo Articuno is one of the best Pokémon in this game: it's recruited at level 53 (I believe it's the highest-leveled recruitable Pokémon in the game? Kecleon and Skarmory are higher level), comes with a room-clearing move, can learn Fly if you need it, and its body size lets you avoid having to turn down constant recruitment requests by teaming it up with the starter and partner. Moltres is probably better once it gets Heat Wave, but that's over 20 levels after being recruited.
Additional Pokémon
Something I wanted to do differently this time was to use Pokémon other than my starter, partner, and Articuno. I recruited a bunch of Pokémon that I liked and/or had moves I was interested in with the intention of getting them all to level 100 and max IQ. Progress has been rather slow, but I'll probably get there eventually. IQ in particular is pretty difficult to grind when you have multiple Pokémon of each type and have to split up Gummis among each of them.
I've spent more time training some of these than I have others, so a few of them will have suboptimal movesets at the time of this writing. I plan to improve them once I get around to training them.
Pichu and Charmander were specifically recruited to eventually represent my starters from my previous two saves.
Miscellaneous
I'm not actively training these Pokémon, but I do still use them for various purposes.
