Troy Mariner vs. Cobra Fang

Troy Mariner vs. Cobra Fang is a fight fought between Independent Mage Troy Mariner and Mages of the Dark Guild Cobra Fang.

Prologue
Troy Mariner travels to the Cobra Fang Guild Hall after two of the Dark Guild's members attempted to collect a bounty placed on him. After arriving at the Guild Hall, Troy destroys the building's entrance with his Water Dragon's Iron Fist, revealing over a dozen Cobra Fang members. Troy then charges at the group.

Aftermath
With the entirety of Cobra Fang's guild members defeated, Troy makes his way out of the now ruined building and is faced by a surprised Erza Scarlet. The two then engage in a conversation, in which Troy explains his resolution of Cobra Fang's attempted assassination and Erza explains that she was hired to destroy the Dark Guild.

After explanations were revealed, a frightened Cobra Fang rises out of the rubble and makes a desperate attempt to flee only to be blasted by Troy's Water Dragon's Roar. Recognizing the Dragon's Roar as a Dragon Slayer spell, Erza realizes that Troy is the notorious Independent Mage: Leviathan. Seeing great potential, Erza offered Troy to join her Guild: Fairy Tail, but Troy declined. Even though she respected his wishes, Erza explained that his actions in destroying Dark Guilds while not associated with any official Guilds are considered illegal by the Magic Council and if he continues to do so, they'll eventually arrest him. Erza then departs, leaving Troy to ponder on her invite.
