Powers and abilities

Monster Physiology (Ghosts)
Pocket Reality Manipulation (Created Otherworlds and the monsters inside of it, that are made based on places he has been and fragments of his memory)
BFR (Brought 4 of the remaining sacraments into the Otherworlds without them knowing, which according to the victims it's as if they were dreaming, while their physical bodies remain in the real world)
Damage Transferal (If someone is injured or killed in the Otherworlds, said injure or death also happens in their physical body in the real world)
Necromancy (The souls of people who are killed as part of the 21 sacraments become ghosts that roam Walter's Otherworlds)
Limited Corruption and Possession (Type 1 and 2. Corrupted Room 302 through the Ritual of The Holy Assumption. After Walter's failed attempt to kill Eileen, her body in the Otherworlds was corrupted with reddish marks that slowly put Walter's influence on her [and could speed up if she is hurt], this is shown when she was partially possessed during the game, and in the end, completely possessed)
Pain Manipulation (Caused people to have chest and head pains in the 21 Sacrament ending)
Superhuman Speed
Enhanced Intangibility (Ghost Walter is completely untouchable within Room 302's core)
Afterimage Creation (Can create afterimages when moving)
Monster Physiology (Special Mutation; Giant)

Weaknesses

Just like other ghosts, a considerable amount of damage can render him temporarily unconscious. Walter's Corruption and Possession appears to be limited and only works against specific people, as he has had the opportunity to possess Henry multiple times and has never done so| The damage that the Conjurer takes is also transferred to Ghost Walter. If the Conjurer is pierced by all of the Spears of the Holy Mother [after being affected by Walter's umbilical cord], Walter loses his immortality, intangibility and his speed boost | The Conjurer is harmless, the only thing he can do is move his head.

Ranked tied for #9 of 114 in Silent Hill by strength.
