Pitaya, previously known as Pyromaniac Roy and often referred to as simply PR, is a Moderator on GameFAQs, who frequently posts on the Super Smash Bros. boards, as well as several other system and game boards on the site.
The Smash board's resident moderator and hero (or villain, depending on one's perspective and/or moderation history). Generally only relevant due to modship, but is otherwise fairly well-liked.
In Smash, Pitaya mains Ness, and enjoys bathing in the salt of his opponents as he back throws his way to scrubby victory. His NNID is Pitaya. Surprise.
