Welp.

Welp.

Umm if anyone is also interested in links~

“DIO also notices that he has especially weak control over his left side(https://www.youtube.com/watch?v=G6UsDWEwtH0 around 1:38)”

“The leg is on the left side, which you can see here (http://bato.to/read/_/256091/jojos-bizarre-adventure-part-3-stardust-crusaders_v28_ch258_by_jojos-colored-adventure/3).”

“This is important for later. DIO tries to re-attach the leg, but it’s still weak and flimsy, especially when Jotaro kicks it using SP before taking down DIO completely (http://bato.to/read/_/252897/jojos-bizarre-adventure-part-3-stardust-crusaders_v28_ch264_by_jojos-colored-adventure/5).”

“HOWEVER when DIO gets juiced up on that sweet, sweet Joestar blood, he is at his most powerful in the series, and even says that he’s never felt this good before (http://bato.to/read/_/245253/jojos-bizarre-adventure-part-3-stardust-crusaders_v28_ch263_by_jojos-colored-adventure/2).”

I was also pissed about the Jotaro/DIO 1 hit KO initially, but here’s my understanding of what happen “behind the scenes”~In multiple times in Part 3 of jjba, DIO talks about how Jonathan’s body is resisting him. DIO also notices that he has especially weak control over his left side. I take it to mean that in the left side of DIO’s (or I should say Jonathan’s) body, Jonathan’s spirit is still opposing DIO. (cont.,1)

Jonathan’s control over the left side of the body is limited to slowing down DIO’s healing, but his spirit is still present. DIO realizes this, and knows that he must kill/drink the blood of the remaining Joestars to take full control of Jonathan’s body and banish him completely from the body.

But before DIO is able to “power up” on Joestar blood and become virtually indestructible, Jotaro cuts DIO’s leg off. The leg is on the left side, which you can see here. This is important for later. DIO tries to re-attach the leg, but it’s still weak and flimsy, especially when Jotaro kicks it using SP before taking down DIO completely.HOWEVER when DIO gets juiced up on that sweet, sweet Joestar blood, he is at his most powerful in the series, and even says that he’s never felt this good before. I take to mean that DIO feels like he now has utter control over his body (and his destiny), and that Jonathan’s spirit has left the body. What DIO fails to take into account is that Jonathan’s spirit isn’t completely wiped out.The left leg, which was severed and re-attached recently, probably didn’t have the Jojo/DIO blood fusion reach it because it was still healing. Jonathan’s spirit was able to cling to the leg.I think that when Jotaro punched the leg, he awakened Jonathan’s spirit through direct contact with one of his descendants (or rather one of his descendant’s stands), and Jonathan’s spirit was able to travel through DIO’s body and break him down. 

So basically, DIO wasn’t defeated by Jotaro directly, it was the spirit of Jonathan Joestar, still fighting for good even from beyond the grave, that lead to his downfall!!! Welp, that was my headcannon, at least! :D_____

I do like this theory, it’s always been Jonathan and Dio after all. Jonathan’s spirit holding Dio back over one hundred years later, an endlessly convoluted relationship.. mm yes. Jonathan did say right from the start that he couldn’t let Dio live like this, and he intends to hold true to that promise, even if he can no longer challenge him face to face, he’ll work within
