In Jade Cocoon's case, it had a really genius pedigree system where on the most surface level your monsters had a body type and a skin type that they'd retain from either parent based on the order you fuse them in, and also a balance of elemental affinities(fire, water, earth, wind), plus spells and attack bonuses to inherit, like stronger or more accurate claw attacks for things with an obviously accommodating body type, but also petrification, sleep, and poison effects. The real fun of it was that subtle (and sometimes not so subtle) changes to body type would pass over as well. So if you fused a winged monster as the subtype into a non-winged maintype the new monster would retain the basic body of the maintype but also grow little wings, which could subsequently grow bigger either as the monster leveled up thru its 5 stages of growth, or if you later fused more winged subtypes into it.
Between balancing function and aesthetic it was super engrossing, even if the graphics bumped into a lot of funky results just by way of the procedural generation of the fusions. For sake of example here's the pedigree of a monster I started with in a play thru i did a while back
