Arkun has the same build of the actual Aquamarine, but with different clothing. He wears a dark blue male japanese school uniform, with the chest opened, revealing that he is also wearing a white shirt under it with a blue diamond insignia on the chest. He is also wearing white gloves and blue shoes. Along with the gloves, his wand is turned into a bacelet when it isn't being used.


At first glance, Arkun is innocent. However, when he is bothered or angry, his behavior will change. He begins to act snob, smart and way more evil-ish than he was before.


Arkun was made for Blue Diamond.


While Arkun can retreat to his gemstone when badly damaged, can summon a light out of his gemstone and can fuse, but being a Era 2 Gem, Arkun can't shapeshift and he wasn't made for fighting.

Unique Abilities

  • Water Wings - Arkun can also summon butterfly-like water wings on his back. However, he doesn't exactly likes them and doesn't uses them too much, and when he does, he uses it really quickly.
  • Good Memory - Arkun has a good memory, being able to remember a lot of things that happened even months ago, especially things for his missions.

Additional Tools

  • Wand - Like Aquamarine, Arkun also has a tractor beam wand. They are of the same color and shape while being used, but while it isn't, Arkun wears it around his arm like a bracelet.
