Chapter 58

The Ripple and the Ultimate Life-Form is the fifty-eighth chapter of the JoJo's Bizarre Adventure manga. It is also the fourteenth chapter of Part II: Battle Tendency.

Summary
Joseph questions Santana about his species and repeats formal greetings to him. Baffled, Speedwagon asks Joseph why he is doing this and Joseph says he wants to determine if Santana is a good life form. Stroheim argues that he is evil because he killed his men, but Joseph writes this off as Stroheim provoking Santana to kill his men by awakening him from his slumber. Joseph adds that he only came to take Speedwagon back with him to New York, and there is no reason to provoke conflict with Santana if he isn't evil.

Joseph continues to greet Santana, trying to get him to talk, but Santana ignores this and starts to walk past Joseph. Taking this as offensive, Joseph trips Santana to get him to speak. Santana's leg goes through Joseph, to his shock. Santana approaches a dead officer's machine gun and asks what it is, as he has never seen anything like it before, to no reply. He proceeds to dismantle the gun, showing that he is an amazingly fast learner with high intellect.

Not bothered by this, Joseph continues to seek Santana's attention. Eventually Santana uses his Rib Blades attack to eat Joseph, but instead of absorbing Joseph into him, Joseph is repelled back by his own Ripple energy. Confused by this, and by the fact Joseph feels different than any other human he has encountered before, Santana tests to see if Speedwagon is like Joseph, and confirms that Joseph is truly one of a kind. An enraged Joseph picks a fight with Santana, trying to punch him with the Ripple only to find that his current Ripple does not work on Santana.
