It's really incredible, as this is the first technical voltstandig (cause he did have one wing) and it's the only voltstandig (even though it's a pseudo voltstandig) that has been achieved without Yhwach's support
Lats Stilz is more of the prototype of Volstandig, not "Pseudo" ... Lats Stilz is Quincy technique ... While Volstandig is Yhwach gift to the Quincy to use Lats Stilz without the drawback but weaker ...
