Bob

Bob is the founder and the Guild Master of the Blue Pegasus Guild. Bob, for some reason, tries to look very feminine.

History
He is an old friend of Makarov, the Guild Master of Fairy Tail, Porlyusica and also Goldmine, Guild Master of Quatro Cerberus. For some reason, he left his former guild (it's very possible that it was Fairy Tail), and decided to create a new guild, Blue Pegasus. One of his first members was Hibiki Laytis, who is currently his unofficial "right hand".

Lullaby arc
Bob was seen at the Regular Meeting for Provincial Guild Masters telling Makarov that he likes the mages over at Fairy Tail and telling him not to hit on Lucy Heartfilia. He is later seen hiding in the bushes watching Makarov and Kageyama speak and stopping the other Fairy Tail mages from interfering. He was also among the few who watched the Lullaby take its true form and afterward explained about Dark Mage Zeref. Also he was seen flirting with Kageyama both before and after Lullaby was defeated.

Loke arc
With Makarov, Mirajane and others he was invited to the play "Frederic and Yanderica" where Team Natsu was acting in. Bob was briefly seen in flashbacks scolding Karen because of her mistreatment of her Celestial Spirits. He was also the one who tells Loke about her death.

Magic and Abilities
Caster Magic User: Bob, as a Master of Blue Pegasus guild, and former member of Makarov's team, he must be powerful mage, but currently he only demonstrated two magical abilities. However in the anime Erza commented that Bob was a mage that could even make her own Guild Master, Makarov "a run for his money" implying that he is indeed a great mage. Bob greatly intimidated Karen Lilica when he was lecturing her.

Going Through Solid Objects: Shown in Loke memories, when he could pass through the bar while he was talking with Karen about her Spirits.

Flight: Using his tiny wings, he can float above the ground.

Trivia

 * In the anime, Bob was shown to be quite handsome in his youth. He had striking similarity to Julius in RAVE Master, who is, ironically a member of Oracion Seis in the mentioned series.
