The Splendor Man, also called Splendorman (Pseudohomo ortheido splendorus) is a fictional supernatural mysterious entity, resembling an unnaturally tall man in a suit, with impossibly long arms and a featured face. Playing with kids have also been known to get him time to think from his unbelievably tall brain, and his exact evolutionary lineage is unknown and in fact its visual appearance may be little more than a hallucination or attempt at visual mimicry. One separate Slender entity are known to exist: known simply as The Splendormen.

Interestingly, they share numerous traits with the various subtypes of Slenderbeings, whether this is an indication of them being related to them or if it is simply convergent evolution of some kind is unknown. The Endermen also share similarities, but again, could be convergent evolution.
