Mummy (Virus)

Mummy is an artificial virus created by the All-Star Queen and used as a weapon by the prison guards of Udon.

Description
Once the virus hits a person's skin, it would cause the person to experience massive fever and bleed as a result. Once it reaches the final stage, the victim becomes dry and pruny like a mummy. Rather then being killed, they become like zombies, and would feel everlasting pain. The disease is also highly contagious, and anyone who comes in contact with a victim will become infected as well.

The virus can also be administered in small amounts using "Excite Bullets" wielded by Daifugo, or in much larger quantity using an "Excitement Shell" as shown with Babanuki.

History
When Luffy began an uprising at Udon prison along with Chopper, Hygoro, Kikunojo, Raizo, and Kawamatsu, Babanuki ordered the other prisoners to restrain the young pirate captain. Having had their wills broken by the Beasts Pirates, they regretfully obey. Daifugo then starts shooting Excite Bullets into random prisoners, knowing they will eventually spread it to Luffy.

But then Luffy grabs the prisoners and forces them into a big hug, contracting the virus on purpose as a sign of his promise to Tama to free them and the rest of Wano from Kaido's control. Seeing that his words are affecting the prisoners, Babanuki decides to finish it by using an Excitement Shell shot from his elephant's trunk to murder them all, but Luffy predicted this using his Kenbunshoku Haki and tied the trunk, causing it to explode inside the prison warden instead.

Trivia

 * The Mummy virus is somewhat similar to the Ebola Virus. Both make the affected bleed from the orifices and gets high fever.
