Poco

Poco (ポコ,) is a minor character introduced in Part I: Phantom Blood. The character is portrayed as an ally of the protagonists.

Personality
Poco is introduced as a mischievous and cowardly boy who steals the group's supplies. Later, however, especially when Jonathan Joestar is losing against Tarkus, Poco was shown to be brave, willing to risk his life to help the group. He also worries about his sister, who has been taken captive by Dio Brando.

History
Poco was a coward boy who was always bullied by other kids, but was protected by his sister. When confronted by her about when he was going to fight back and live on his own Poco answered that he would do this "tomorrow", getting slapped by his sister soon after. When Dio Brando took shelter on Windknights he brainwashed Poco to lure Jonathan Joestar into a trap.

Phantom Blood
On their way to Dio's castle, Jonathan's group encounters Poco, who is introduced as a pickpocket who steals the group's supplies. In reality, he was under Dio's mind control and while he is able to get away from the group quickly, Poco quickly finds himself under danger from Dio's zombies. Luckily, he is saved by Jonathan, and witnesses the serious situation of the group.

When Jonathan fights a losing battle against Tarkus, Poco finally grows courage, willing to risk his life to open the door to allow Zeppeli and Speedwagon to come to Jonathan's aid, though neither of them are willing to comply with his wishes with regards to the ethical dilemma of risking the life of a child. He then accompanies the group to the fight against Dio, just to save his sister, and is protected by Straizo from Page, Jones, Plant and Bonham for the remaining of the fight. After the battle's end, he last appears with his sister and the other characters on the port to wish Jonathan and Erina Pendolton a good honeymoon.
