A Dragon Slayer mage who is a member of the Guild Oracion Seis.
Cobra is a member of Oracion Seis, one of the most powerful dark guilds. And like his fellow members, he also seeks Nirvana, an incredible magic sealed long ago. Prior to joining, he was enslaved in the Tower of Heaven as a young boy under Jellal's reign until Brain came and selected him to become apart of his guild with Jellal's permission.
Cobra, created by Hiro Mashima, was designed to have features that resembled a snake, in correspondence to his name such as his snake-like eyes and nose. In addition, his poison dragon slayer magic and pet snake only reinforced his snake-like image and characteristics.
Cobra appears along side his guild, ready to annihilate the allied forces of Fairy Tail, Cait Shelter, Lamia Scale and Blue Pegasus. However, his primary target throughout the battle is Erza who manages to hold her own even after three other Oracion Seis members joined the fight until Cobra's snake, Cuberos, bites her arm, severely poisoning her. After telling her that he would not kill her since the poison will slowly do its job, he along with the rest of the Oracion Seis leave the defeated team with a kidnapped Wendy (and Happy).
Once Jellal is revived and leaves the Oracion Seis base, Brain tells Cobra via telepathy to follow him in which he not only succeeded but bore witness to the activation of Nirvana first stage. As he watched the event, Erza shows up, and Cobra thinking that she should not be alive and that she must be stopped from harming Jellal, proceeds to do so until he overhears about Jellal's amnesia.
He then confronts Jellal, who cast a Self-Destruction Spell on himself and Nirvana, and demands he undo the spell. With Jellal refusing to adhere to his demands, Cobra attempts to break the code to the spell but is horrified when he is unable to do so. However, Brain appears and easily deactivates the spell without a cancellation code and activates the second stage of Nirvana with a triumphant Cobra.
Unlike Natsu, Cobra obtained his dragon slayer powers by implanting lacrima into his body enabling him to possess the powers of a poison dragon slayer. This power gives him the ability to change his hand into a dragon's claw surrounded with poison that is so corrosive that it can burn his opponent and decay all that it touches. He can also eat poison mist provided by his snake pet, Cuberos, to replenish his energy and add a greater effect to his attacks.
