Does anyone think...

Sorry, didn't mean to sound sarcastic. Sometimes I do but I don't really mean it. I just really wanted to know it. I see now, reading it, that it could be misunderstood. But to me they still look kekkei genkais, cause I don't think he would have added more experiments on the CS. But of course we can't be sure until clearly stated.

i'm sry too, i was too harsh. After reading this page, i think u might be right. ukon and sakon do have bloodlimit. But the guy with 4 arms who creates webs out of his mouth, I think he was bitten by a radioactive spider.

Kekkei Genkai

Thank you. Let's call them potential kekkei genkai from now on, shall we?
Oh and you don't need to be sorry, you were right, I was a bit conceitful and you weren't like stfu. Moreover you apologized in advance and put on the link to show I might be partially right, or that at least there are others who think like me. So thanks again.
And yep, that's the most likely cause of his unreasonable number of arms. Though I always wondered for Spidey why did he grow more arms and no legs.

And it looks quite like we took over the thread. Sorry everyone.
