Erza Scarlet, Evergreen & Max Alors vs. Cobra

Erza Scarlet, Evergreen & Max Alors vs. Cobra is a fight that takes place during the Key of the Starry Sky arc.

Prologue
With the Reborn Oración Seis having possession of the Infinity Clock, Fairy Tail decides to split out into some teams to take them on. Cana Alberona, using her cards, selects the teams and their destinations. One of the teams formed consists of Erza, Evergreen, and Max.

Erza’s team journeys towards a mountain and begin to climb it. During the travel, Evergreen complains from walking such a rocky terrain in high heels, though neither Erza or Max could care less about her ordeal.

Sometime later, now in a more forested area, the group encounters Dark Mage Cobra and a fight ensures between both sides.

Battle
Cobra attacks the three Mages and manages to injure Evergreen and Max. He turns to the unscathed Erza and asks if she knows Cuberos. From her silence, he concludes that she does not. Max asks how can he be so sure and Erza explains that his Magic allows him to hear what others are thinking. Following her explanation, Cobra uses Sound Wall, which nearly destroys the entire terrain. Luckily, Erza used Requip and transformed into her Adamantine Armor to protect her and her guildmates. She theorizes what Cobra’s Magic is actually able to do before changing to her Robe of Yūen.

Erza lunges at the Dark Mage but he easily dodges her attacks, reminiscent of their first battle, and he even manages to strike a blow near her left breast. When she maintains composure, he compliments her. Erza tries to think back about how Natsu originally defeated Cobra, basically by not thinking and talking in a really loud voice, but Cobra claims those tactics won’t work against him anymore. As he thinks more, he remembers how he lost Cuberos because of Fairy Tail and viciously attacks the group again, injuring Evergreen and Max once more. He then asks for them to return Cuberos to him, confusing Erza.

Max attempts to fight back using a combination of Sand Slash and Sand Trap, the latter being used in coordination as a decoy for the first move. Max tells Erza to attack and she goes in for the kill, but Cobra has already figured out their plan, and counterattacks with Sound Magic. He then goes to strike Erza but instead hits Max, who receives a moderate wound to his back. Cobra claims that the friendship between him and Erza sickens him. Erza notices a sad tone in his voice and, thinking back about his constant talk of Cuberos, says that even he can overcome such heartache.

Cobra remains silent after this but hears Fiore Guards talking in the distance near a church. He realizes how much time he's wasted and leaves, holding a ruby dagger with him.

Aftermath
Erza looks on as her opponent flees the scene.
