Akzer

"Who's Akzer?"-Blackout
Akzer was the former lord of the Seven Metal Seas, meaning he was a pirate lord on the planet of Liquid-Metallicon. He was also an apprentice of Caiaphus, believed to be the second in command of the Order. He also seems to know Sephiroth in a way, and has struck a deal with him: betray his master and get the AoC to become his new army, while helping Sephiroth get the Keruvim.

Akzer was a novice during the Apprentices' battle against Blackout, and vowed to bring the organization back, and the Makuta to his knees.

He had rescued Klak during a battle, and helped train him in one of Makuta Caiaphus's dangerous tests. Due to his defeat in this, Akzer then developed a grudge against the young Makuta, and transported away from the temple to his old ship, the Mazkertis, taking its power core. He used it to find Klak, but had a minor sidetrack: He transported to the Enterprise, and was imprisoned with the other crew members when Naju took over. He quickly used his wit to trick the Great Being into letting him go.

Akzer then teleported to where he found Klak, and attacked him. There, he revealed his secret plans to betray the AoC, and to use them as a crew to retake his pirate kingdom. The swashbuckling fellow fought as hard as he could, but since he was subject to the Makuta's anger, he was crushed into a can, and died.

However, a part of him survived. Naju, then a dying apparition, brought Akzer back to life, giving him his powers. Our pirate lord attempted to get Tahar'ok to kill Klak for him, but instead found himself becoming the servant of the Tahar'. Therefore, he went to the battlefield where his murderer had activated the Keruvim. However, a taste of a Great Beings power, and his betrayal instinct got Akzer killed by Tahar'ok himself.

Post Morten once again
An unknown amount of time after Akzer's second death, Keichi was exploring a planet with Ravat, when an appartion of Akzer began to attack them. According to legend, this planet projects the memories of those in the area as certain enemies.

Powers and traits
Akzer was a master swordsman, and can open several portals. He is also able to fill many beings' minds with illusions, as he did to Klak while the latter stayed in a virtual world. He can be quite the trickster, just as any pirate is. The apparition of Akzer only has the attacks Keichi remembered him using. Whatever these are, we don't know.

Akzer's species are reptillian humanoids who grow a metallic exoskeleton (much like armor) at a certain age. This means when Klak killed him, his entire body was crushed within.
