OK the question is partly a joke... But let's be honest, that's a Guyver! or at least some sort of clone like Aptom. What's he doing in Tensei Shitara Slime Datta Ken? 😂 Curious to hear people's hypotheses on how he got there. Maybe Otherworlders can come from other parallel Japanese universes too?

Oh yeah I'd like more Zoanoids and Dr. Barcas/Balcus too! Or maybe I've actually already seen someone like him in TSSDK?
