Pokemon Mystery Dungeon Rescue Team DX, like practically every Pokemon game before it, has you choose your starting Pokemon when the game begins. We'll show you which starter you should pick and what their different strengths are.
Which Starter Should I Choose?
Though at time of writing only the demo for Mystery Dungeon has been released, we've already learned a lot about the game, and can infer more details by looking at the original Mystery Dungeon that DX is based off.
For one thing, it's important to remember that unlike starters in other Pokemon games, you'll be stuck with this choice for a while. In Mystery Dungeon you're not just choosing a minion, but what you are going to play as for the majority of the game.
Still, the new movesets given to the Starters means that things are a lot more even this time round, with diverse abilities given to all the starters so as to make a level playing field. That being said, if the original games are reliable sources of information, this would mean that Charmander and Pikachu would be particularly powerful choices, as later on they both learn very powerful moves: Heat Wave and Thunderbolt respectively. Thunderbolt is a powerful Electric move that strikes every enemy around the user for massive damage, but Heat Wave was famously broken, doing high Fire damage to every enemy in the same room. This meant that Charizard could wander into a cave, see several dozen goons advancing in its direction, and just wipe them out in a single attack before moving on with its day. If that move has been carried over to Mystery Dungeon DX, it has the potential to be a real game-changer.
The other thing to take into consideration is manoeuvrability. Again, we're inferring details from the original game, but a large element there was the ability to cross different kinds of terrain with different Pokemon. For this reason, Fire and Water types are good choices, able to walk across lava and water tiles whenever they want (Ghost types can also walk through solid walls and any sprite that levitates or flies can cross any surface, but there's no starters who match those criteria.
It's pretty clear at this point, but we'd recommend Charmander as a solid starting choice. It has a good range of moves with some real power in the later game, greater potential for travel and also looks good in the scarf. It shouldn't make the game trivial or easy, but it will give you an edge that the others don't quite offer.
Which Partner Should I Choose?
This is a little harder to choose, because whatever you pick, you'll want a partner who complements and negates many of the weaknesses that you have. For example, if you pick Pikachu to play as, you'll be weak to Ground-type attacks, so you'll want to pick either a Grass or Water-type, both of whom will be able to take out Ground-types easily. It'd be a bad idea, on the other hand, to pick a Fire-type, as then you're both weak to Ground and run the risk of getting stomped on by any random Cubone.
How to Pick Starters in Mystery Dungeon
As the game begins for the first time, you'll be given a personality test to determine which Pokemon is right for you, giving you eight hypothetical questions and deciding what kind of person/Pokemon you are as a result. Don't worry if you don't like the final result, as the game allows you to choose for yourself after revealing its own suggestion. Still, you need to be very sure that you won't both these two Pokemon - they'll be your team for the majority of the game.
