Alessi

=Character= Alessi (also sometimes translated as Alessy) is an assassin hired by Dio Brando to kill Jotaro Kujo and his friends in the third part of the series. He possesses one of the Egyptian god stands, Sethen (likely named after the god Set) which has the power to turn anyone who stands in it's area into a children. Sethen extends from Alessy like a shadow, and proves to be a formidable nuisance to the protagonists until the de-aged Jotaro is finally able to punch Alessi in the face, knocking him out cold. He is characterized as a sadistic, yet cowardly man who will only fight those who are weaker than him because he knows he can win. His most telltale characteristic is his bizarre hairstyle, which resembles a dust mop with decorative beads tied to it in intervals. He also carries an oversized hatchet with him that is engraved with the word 'Ax'.

Alessi has not been seen in the series again thus far, it is unknown what happened to him after being defeated by the protagonists in Part III.

JoJo's Bizzare Adventure (Arcade/PS1/Dreamcast)
Alessy is characterized to be a joke character (such as Dan from the Street Fighter) with his ridiculous animations and over the top attacks, but is in fact a powerful character. His active Stand possesses incredible range, and can be extended even further by holding the Summon button down while calling it out. It's weakness however: Alessi will not be able to attack aerially with it active since Sethen is a shadow, and cannot leave the ground.

Alessi's Tendum ability allows him to move and attack a very rapid pace for a short period of time at the cost of an energy meter, and even chain it with another of his Super Abilities, Ushi-Ushi-Ushi, which makes Sethen rise from the ground and cause area of effect damage to the opponent. After any of his supers successfully connecting, (excluding Tendum without chaining it to a de-aging attack) his opponent will be shortly turned into a child (or something much more hilarious, such as Rubber Soul being morphed into a portly woman) and rendered defenseless against the onslaught of Alessi's 'Ax'. All of this makes Alessi a potentially deadly opponent in the right hands, and nothing to shrug off.
