so after much thinking and some discussion, we've finally figured who's the only person idw1 jhiaxus would accept as a partner if he was ever interested in one (unlikely) : bludgeon
minion/mastermind complex (jhiaxus) meets looking for the biggest evil to minion for (bludgeon)
both horrendous scientists
(it can't be Shockwave because imo Shockwave is basically Jhiaxus's mentee/kid/son in the adopted familial sense)
bludgeaxus
this isn't even a crackship because they do work with each other in e.g. Robots in Disguise 2012 but it is what we would call a crackedship (depths of lore unlikely ship between characters who know each other)
blessed be cloud jhiaxus for being a pirate lesbian leading an order of lesbian warriors fighting for the multiverse instead. they have so much more going for them (yes technically Yellow Order bots being the equivalent of sapphics is unconfirmed and unsuggested but what do you want me to headcanon conclude they had a whole planet for themselves. if the histories of same gender love nuns and priestesses has taught me anything...)
