While not an attackable enemy exactly, Valtiel is, according to the team
behind the game, a "gatekeeper" of sorts, or rather "valvekeeper," who is
involved in the change between the "real" and "alternate" worlds of Silent
Hill 3, along with other tasks which you could only call the "operation" of
the alternate worlds.
Apart from this task, Valtiel moves much like the Slurper's in that he
scrambles across things, except that Valtiel can wall on walls and also
just walk normally like a human being when needed. The entire fact is
that it could also be said it looks very human indeed, more so than other
One final thing which is worth noting about Valtiel is that should Heather
die in the middle of combat, randomly you'll get a scene which shows
Valtiel come along and grabbing the deceased Heather's legs and dragging
her off into the darkness.
