XIII is cool (the game, not the user)
Known more widely as XIII_rocks or just XIII. The XIII is cool account was axed in 2005 by Smurf's antics, and the replacement account name "XIII_rocks" has been used ever since. His name is a reference to the videogame XIII, and not Final Fantasy XIII, Red XIII, or Organisation XIII, or anything that is not the Ubisoft videogame XIII.
XIII used to co-own B8UCA.
He also got a perfect oracle prediction twice in one contest, Summer 2006, predicting Jill Valentine's 62.03% win over Sheena Fujibayashi and Vincent Valentine's 52.59% win over Ganondorf perfectly:

XIII was credited by SBAllen as the one who named the 2011 Rivalry Rumble.
From June 2011-2018, XIII was very active B8UCA. He held almost every title multiple times, and had the longest tag-team title reign in history along with Whiskey_Nick, and held the various titles in UCA for the longest cumulative time. After 6 months with UCA, he became the GM of Tuesday Night Ruin and, after Tom Bombadil's departure, became 50% owner of the company with Dr_Football. XIII helped UCA thrive until, alongside a returning Tom, he announced UCA's closure in February 2018.
XIII won the Karma contest in the expert challenge of Character Battle IX and as such won his own private board, which he christened board8chat. He was one result away from winning Character Battle X, but Mario lost to Cloud.
In April 2019 XIII became a GameFAQs moderator.
