Impostor Captain Tennille

Mercenary

Agents of DIO

Dark Blue Moon

The impostor Captain Tennille is a mercenary sent by DIO to assassinate the Joestar group that are heading to Egypt. after killing the real captain, he secretly boarded the vessel and plans to kill the members of the group one by one.

The impostor appears to be very patient, as he originally planned to separate the protagonists and kill them one by one. Once his schemes are spoiled by Jotaro, he does not lose his calm, saying that it will be no problem for him to kill them all at once from underwater. He also enjoys guessing what his enemies are thinking.

He also seems to be fond of the ocean, being rude towards Jotaro after seeing he was smoking and asking if he was going to throw the ashes and the cigar in the water.

Being a Stand user, the impostor's Stand, Dark Blue Moon, is mostly effective in the aquatic environment. It has a high enough range to attack anyone even without the impostor being in the water. it can swim very fast, and it's able to create whirlpools by spinning its webbed feet very fast. it can also help it stand user increase his lung capacity by allowing him to breathe underwater for more than 6 minutes. The Stand's hands are very sharp and strong, making them effective weapons. the hands can be able to destroy anything, or slice up things in two. Dark Blue Moon can also use its scales as projectiles, throwing them at the enemy. Wendy scales are thrown, they can also flow through the water currents and slash anyone who tries to swing through the water. It can also create barnacles. for example, if another stand makes contact with Dark Blue Moon's skin, barnacles would begin to form in said part. these barnacles drain the target of its strength, and allows the Stand slight control over the infected body parts, which allows it to drag its foes back into the water if they try to escape it.

The impostor is an assassin that appears as a tall, extremely muscular man possibly in his late thirties. His appearance is rather inconspicuous as he only has a blonde crew cut and a moustache, followed by a soul patch for his facial trait.
