Shiryu

Shiryuu of the Rain is a former Chief Guard of the Great Jail Impel Down, and a current prisoner of the place he once guarded.

Appearance
Although Shiryuu has not made a personal appearance, his silhouette was seen in a flashback. There, he was seen to have devil-like wings, like Magellan, along with an officer's hat that is similar to the one Domino wears.

Personality
Shiryuu seems to love to kill people. He massacred many prisoners within the walls of Impel Down, claiming them to be "trash". This behavior may be due to his hatred towards criminals, or that he may be a homicidal psychopath. Regardless, he was abusing his authority over the prisoners, similar to how Rob Lucci abused his CP9 permission of killing citizens for amusement.

Abilities and Powers
As former chief guard of Impel Down, Shiryuu has command over lower ranking employees of the fortress.

He was also said to have comparable strength to Chief Warden Magellan. However, since Magellan's work hours are limited by his diarrhea, Shiryuu is considered more dangerous.

Shiryuu is seen to be holding a katana when slaughtering prisoners. The handguard for the katana resembles those found on medieval broadswords.

History
Though the guards of Impel Down have permission to kill prisoners for security reasons, Shiryuu has heavily abused that privilege, and killed many prisoners for his own pleasure. When confronted by Magellan, Shiryuu's abuse of his privilege was revealed and he was deemed to be a menace. For that, he was sentenced to Level 6 for life. As Level 6 erases the criminals' record from history, despite Shiryuu's crimes were brutal, they were not heard of by most prisoners, such as Mr. 2 Bon Kurei.

When the gaolers reach Level 6, which they atempted to flood with knock out gas to capture Luffy ,Ivankov and Inazuma, he informs them that they escaped, along with Jimbei and Sir Crocodile and tells them to pass word to Magellan that he would be willing to lend him a hand.

Translation and Dub Issues
If translated to Kanji, "Shiryuu" (死竜) can literally mean "Death Dragon" in English.
