people get too caught up in the technicalities of what makes the mother grub a "lusus" imo. canonically a lusus is just any of the wide variety of subterranean monsters native to Alternia; just to look at them, they're clearly not all the same species, so I don't see why a mother grub can't be a lusus AND a big mama troll. whether they're literally white because they live underground or they're just stylistically white like the rest of the comic's white characters is all secondary to that.

I was gunna ask how they'd get a jade wiggler to even turn into a mother grub on Earth C if that's what's required but I guess they do have the ectobiology huh LOL. I agree that drones are also presumably another casts in the same species; I'll raise you, though, that the jadebloods themselves are also hatched from a kind of unfertilised egg, explaining how they keep getting born despite imperial decrees of virginity. 🙂‍↕️
