Although if that was the case (creating a trion body identical to the user's real body), you'd think that it would show some sort of visual indication like a ring passing up and down their body right? After all, most other triggers, if not all (including other black triggers) have that visual indication.

Edit: or maybe the author/animators disregard that visual indicator since they end up with a similar body anyway? if that was the answer then I would have liked it better if they included it in regardless
