02Appearance
The assassin appears as a tall, muscular man. He has a fairly inconspicuous appearance as he only has a moustache and a soul patch for a facial trait and has a mere crew cut.↗
His attire is similarly ordinary as he wears a simple shirt and pants, complete with gloves, a plain kerchief tied around his neck, and a captain's cap.↗
03Personality
The assassin is foremost methodical, originally planning to separate the Joestar Group and eliminate them one by one. However his plan is immediately foiled by a fairly dull trick from Jotaro Kujo and he immediately dives into the water grabbing Merlai Anne hostage to bait the group. He is quite confident in Dark Blue Moon 's abilities, and believes himself capable of taking on the whole group together once he's in the water.↗↗
"Tennille" masquerades as a stern captain, who is harsh towards stowaways, and chides Jotaro for smoking on deck. His disguise appears to be meticulous, allowing him to infiltrate the ship, deceive the Speedwagon Foundation and crew, and plant numerous explosives undetected.↗↗↗
04Abilities
Stand
The assassin's Stand is Dark Blue Moon, a considerably independent humanoid Stand of great advantage in water due to its ability to swim, create whirlpools, throw its razor scales as projectiles, and create barnacles that drain the strength of its foes.↗
Lung Capacity
The assassin's' lung capacity surpasses the human average by three times, and through practice, his personal record was 6 minutes and 12 seconds.↗↗
05Story
SPOILERS
Background
The assassin is one of the Tarot Card representatives sent by Enya the Hag to kill the Joestar group. Seeing that the Joestar group decided to travel by sea after the attack of Gray Fly, he killed the real captain and took his place. He threw the captain into the ocean and boarded the ship with everyone else, no one noticing that he isn't the real Tennille. He planned to kill the group one by one while inside the ship.↗↗
The imposter at some point plants numerous bombs in the ship to stop Jotaro and company from reaching Egypt.↗↗
Stardust Crusaders (1988)
The imposter captain sails on the boat that the Joestar Group have taken to go from Hong Kong to Singapore. After Jotaro and Merlai Anne are attacked in the water by a mysterious creature, Jotaro has become suspicious of the crew members and believes one of them may be a Stand user.↗
The imposter appears after Jotaro climbs back onto the ship, berating Anne for sneaking on and then Jotaro for smoking on his ship. Jotaro quickly accuses him of being the Stand user. Although Joseph Joestar insists that the Speedwagon Foundation had checked his credentials, Jotaro decides to find out if he is the culprit anyway by playing a bluff on him: he says that breathing even a minimal quantity of smoke causes a big vein to appear on the nose of a Stand user.↗
He tries to take Anne hostage, but before he manages to do so he is stopped by Star Platinum. The assassin, however, drags Jotaro underwater with his Stand Dark Blue Moon, where his Stand can fight at full power. He traps Jotaro into a vortex, attempting to slash him with Dark Blue Moon's razor scales. He even manages to create some sort of little Cirripede that can drain energy from his opponents' Stands.↗↗
Finally, by exploiting Star Platinum's ability to stretch his index and middle fingers, Jotaro stabs the enemy Stand and rips half of his head, defeating him. However the imposter's bombs suddenly go off in the ship, leaving the protagonists to encounter their next enemy Stand, Strength. The assassin, however, is assumedly left to die in the sea.↗↗
