#since ive only explored individual warden/noble pairs so far and it's been sort of implied that you can only do that.

one thing i don't think i ever actually said is that much like canon su fusions, warden fusion au critters can like. stack. like the two guardians of a region (the noble-warden fusions) can fuse together to make one super-guardian, etc. and they follow the same naming pattern as the base fusions, so the regional guardians are obsidian, crimson, cobalt, coronet, and alabaster probably.

but while with the base fusions it's basically up to the noble-warden duo how often they bring it out, the higher-chain fusions are really only for emergencies where they need a Lot of firepower. in part bc naturally as you get more people and pokemon involved it gets harder to keep them all in harmony. there's also probably been a weird cultural thing in the past about diamond/pearl interclan fusion as well. there's also the potential for a fusion that involves all of them, of course, which would just be called straight-up Hisui. but this has probably never been necessary bc it would be so fuckoff powerful that it'd be both difficult to control and also complete overkill
