Yo-Yo Ma

Yo-yo-ma is an automatic stand that appears as a rotund midget with a German style military helmet. He is indestructible, and will even relish in the pain in a masochistic fashion. However, when he is assigned a target by his user, he will follow them and assist in any way possible. This to make the target drop their guard. His ability is triggered when it has the target one-on-one. He will secretly attack the enemy with his acidic saliva, having multiple ways to attack with it; inserting it into the bodies of biting mosquitos, mixing it with water in front of a moving boat causing it to splash onto those onboard. Seemingly indestructible one-on-one, the only safe tactic is to run. If the victim is unable to figure out its method of attack then they'll probably end up dead. The only method of defeating Yo-yo-ma is to kill his user, D&G. The stand is named after Chinese cellist Yo-Yo Ma.
