@weaseax enneacraft has a bunch of these
namely the level 9 forms for orgIA and oknirIA and the level 1 forms for atil.SPIA and archa.TAIL, but we're also missing monsters representing the Individualist and Enthusiast personality types in the enneagram
@TrevorAllenMD monarch has a handful of weird outliers
for example, these guys never got mega forms OR vassals, the first two probably got replaced by ehther and erebus but idk what's up with angmarl
we're also missing a monarch form for edea but i think that'll be in the next support wave
@FarfaYGO goblin biker and heraldic both have an uncle ruckus type thing going on, they hate xyz but are xyz themselves
meklords also a great choice
also sky striker abbreviates to SS and focuses entirely around a blonde blue-eyed white woman so there's gotta be something there
@_scuttlebugzz_@SmolAltNoko tag team fighter like pyra/mythra where you switch between shiver and frye w/ big man appearing in some of their attacks
as for their movesets, shiver and frye each have their favorite weapon classes (stringer and splatana respectively) to pull from + master mega and frye's eels
