The infamous Ender Dragon Monarch, Yhwach, had a loyal cult of endermen and illigers. His cult was widespread throughout The End, with entire villages in The Foggy Mushroomland, The Chorus Forest, The Shadow Forest, The Crystal Mountains, and The Umbrella Jungle. Before he was finally struck down, he had multiple illegitimate children with a few of his priests. A couple of them managed to escape into the Overworld before Yhwach’s fall. One of these escapees is actually Masaki’s grandfather, which is why Ichigo doesn’t need protection when entering realms considered toxic.

*Yhwach’s grandmother Hecate was a particularly well-known and influential Monarch. She possessed gigantism and six horns. She also is one of Yhwach’s biggest critics and refused to accept him as her blood. She would be a fan of Ichigo if they met.
*Yhwach’s mother Morgana possessed five horns.
*Yhwach inherited his grandmother’s gigantism but what truly gained people’s attention was how the top pair fused into a halo. That, coupled with his unusually blue markings, gave him a holy image that was only slightly tainted by his equally unique red eyes.
*If Ichigo did figure out how to unlock his dragon form, he’d be an erythristic individual.
*As prideful as dragons are, there is still such a thing as being too prideful. Declaring oneself a demigod is toeing the line but to declare oneself a God? Yeah, Yhwach got himself excommunicated for that one.
