also re: ingo being The most powerful warden, like, thinking about it. to start with, just in terms of numbers, does anyone besides the protag ever match him? nobody among the wardens can even beat his initial fight number of 3, let alone the full team of the training grounds fights.
hang on i just double checked and yeah. even among the galaxy team members, the max anyone there reaches is 5—the protag counterpart and kamado in postgame fights, and then also beni and zisu in the highest-tier path of tenacity battles. everyone else has 4 or fewer. the only person in hisui who matches ingo for numbers is fucking volo, the final story battle, the last time you ever fight him.
and then you've got levels. on account of the variant horde-type battles the clans use, all the "accessory" pokemon there tend to be significantly weaker than their main. now in the final-stage, people do sometimes break past the max level of 77 w/ 5 efforts in ingo's tougher team—the clan leader's main eeveelution are at 75 and will have effort 7, as will zisu and kamado's teams in the galaxy team path of tencity. kamado makes it to 79 and is, as far as i can tell, the only person to beat that lvl 77 number. so there do exist battles that are tougher than ingo's—though i think it's probably worth keep in mind that in-universe, this is you fighting these guys for the like 5th+ time while they've been aggressively training to beat you. ingo will break out his "tougher" team the like, 3rd time you fight him.
BUT WAIT!! THERE'S MORE!!
ingo doesn't participate in path of tenacity battles with his clan, but his 3 regular battle teams (normal, tougher, and alphas) are not the only ways you can fight him! that's right i'm talking about the PATH OF SOLITUDE. if you fight ingo in path of solitude with certain nobles, starters, and also "baby" or very weak pokemon because fuck you i guess, he will break out pokemon in the range of 80-84. i am fairly certain this is the highest level of any pokemon battle you can have in this game. please look at this fucking matchup:
oh you want to path of solitude with your cute little bnuuy?? lol. lmao. dusknoir also knows a recovery move fwiw. and has completely maxed efforts. in case you weren't having a bad enough time already.
but wait!! we're not done!!
ok so ingo doesn't use that variant horde battle format that the rest of the clans use, right? excepting the alpha battle. well that's not quite true. if you do path of solitude with any of the pla box legendaries—i.e. palkia, dialga, giratina, arceus—he'll also use 3 at once against you in that battle, each one being either a hisui or a modern sinnoh (if it's giratina) starter line. with palkia and dialga, these guys are lvl 50 each. for giratina they're 60.
would you like to guess what he uses to fight you if you're using arceus?
level fucking 87. all at the same time. with max evs. they also have ideal natures for their attacks, y'know, just. in case you were wondering. in case you thought he was going to show you any kind of mercy whatsoever.
i can only assume this is his way of venting some frustration about the whole spacetime kidnapping thing.
