Shiryu

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

Appearance
In a flashback, Shiryuu was seen to have devil-like wings, like Magellan, along with an officer's hat that is similar to the one Domino wears. When his face was shown in his cell, he was shown to have a big nose and seems to wear earmuffs of some sort. He was also allowed to keep his uniform, rather than wearing the prisoners' stripped shirt.

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 jailers reached to Level 6, after their failed attempt to flood the floor with knock out gas to capture Monkey D. Luffy, Emporio Ivankov and Inazuma, Shiryuu informs them that they escaped, along with Jinbei and Crocodile, and states that Impel Down has gone downhill without him, and tells them to pass word to Magellan that he would be willing to lend him a hand. Magellan, after hearing about Blackbeard's intrusion into Impel Down, reluctantly agreed to release Shiryuu to fight him. However, the moment he was given back his sword, he atacked the gaolers who were sent to release him.

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