Rob

Rob was a Fairy Tail Mage who was kidnapped and enslaved in the Tower of Heaven. He was also a close friend of Makarov and Erza Scarlet. He died protecting Erza during the slave rebellion that occurred in order to save Jellal Fernandes.

Appearance
Rob was a lean old man who had white hair and eye brows. He had a black Fairy Tail mark located his lower back, which indicated he was a member of the Fairy Tail Guild. It looked unusually big compared to stamps other members have.

Personality
Rob was once a member of Fairy Tail and believed greatly in freedom that lies within oneself. When he sacrificed himself to save Erza, he elicited her true magical potentials, thus being responsible for her power's growth. Because he hails from Fairy Tail, he values friendship deeply and does not mind dying for his friends' sake.

History
Rob is first seen in a flashback as an old man enslaved with Erza and her friends at the then-unfinished Tower of Heaven. It was he who taught her the true meaning of Magic. He died during the slaves' rebellion in an attempt to protect Erza from the Magical troops of Zeref's cult's attack. His Magical power at the time represented his life force, and his use of Magic to defend Erza resulted in his death. This brought on a change in his charge, and Erza's Magical abilities were awakened.

Magic and Abilities
Caster Magic User: As a former member of Makarov's team, he most likely posseses high-levelled Magical abilities. In the anime, Rob used an apparently unique spell to protect Erza. Although it appears to be a fire-type use of Magic, it is also stated that he 'reflects' the enemy's attacks. It's possible that the spell he used merely reversed the fire-like effects of the incoming spells.

Trivia

 * Rob has a large representation of the Fairy Tail symbol on his back.
 * He was formerly a member of Makarov's team.
 * He is the main reason that Erza Scarlet joined Fairy Tail.
