Just yesterday, we shared the news that Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! will feature 'Master Trainers' - "really powerful trainers" who can be found after you've completed the main story. New information has now been revealed for these intriguing battlers, and it sounds like we have a mighty challenge on our hands.

A lot has been said about the difficulty (or lack of) in these upcoming titles since they were initially revealed, with the overall tone definitely leaning towards an easier experience catered towards those who might be new to the series. To find out more about any potentially trickier challenges in the game, Eurogamer asked Game Freak executive director Junichi Masuda, and designer Kensaku Nabana, just what the more experienced player can expect to find.

Masuda initially responded by highlighting the 'catch combo' mechanic - an in-game feature which rewards you for catching the same type of Pokémon over and over again in a row, but discussion soon moved to the previously revealed Master Trainers.

Kensaku Nabana: And also the postgame content as well, in particular the master trainiers - so these are trainers who are kind of the ultimate trainers of a specific Pokémon, so you will challenge them. So you will challenge them, and then get their title for that Pokémon, so you become the master of that Pokémon if you manage to beat them in battle.

Masuda then went on to explain how this works in a little more detail, revealing that there will be a Master Trainer for every single Pokémon present in the game (ignoring Meltan).

Junichi Masuda: So for me, my favourite Pokémon is Psyduck, so I'd be training my Psyduck amazingly and then would challenge the Psyduck Master, and then gain the Psyduck Master title, and that's something you can put a lot of effort and a lot of time into, if I really wanted to create a challenge for myself - and these Master Trainers exist for all of the 151 Pokémon in the game, so you know, if you want to collect all of the titles then that's something you can really challenge yourself with.

The specifics aren't 100% clear here, but it would appear that you need to train up a particular Pokémon to then challenge the master of that very same Pokémon (who will also battle with that Pokémon), and you'll need to do this 151 times if you want to be the champion of everything the game has to offer. Masuda did go on to suggest that this might be the only real post-game content, other than grabbing Mewtwo and completing your entire Pokédex, of course, but it sounds like a rather substantial undertaking.

Does this sound like an interesting feature to you? Will you aim to be the master of all Pokémon? Share your thoughts with us on this one in the comments below.
