Wut? I'll put it this way. You have a weapon to overpower your enemies, but because you left it intentionally at home, you nearly died. It doesn't make ANY sense. I don't think Tobi is so stupid.
He IS that stupid.
HE SAID SO HIMSELF, THAT HE SEVERLY UNDERESTIMATED KONAN.
So why would he bring all this POWER for Konan and he has never feared a shinobi before?!? Hell... he even went to talk to the KAGES with no RINNEGAN. He is full of himself and I KNOW he thought he would never need a MS to defeat Konan. And as you can see, he didn't need one. FYI
*********************************
(1. ALOTTA TEXT...) ...So you're saying Tobi is using only 1 MS? For me it's more like it doesn't have one at all.
(2. ALOT MOLRE TEXT...) They killed their best friends for achieving the MS, killing other clansmen for their eyes wouldn't matter for them. Also, I've never seen Tobi having drawback for using this 1 MS eye he doesn't have.
Ok. First for #1, I never said that Tobi is only using one MS.
Where did you get that from? I said that he is NEVER using MS eyes, meaning he has them but is not wearing them. I say this b/c it has been my assumption that he is Izuna for a while. If anyone saw Izuna's MS, they would know his identity. There are a few different reasons not to wear a MS, like not wanting it to go blind with it. If you have MS and 1000 other eyes, you might use the other eyes too if you know that your MS will eventually go blind. Think about it.
Second, for #2, who said that Madara/Izuna killed their best friends??? Why couldnt they just WATCH their best friend die (instead of killing them) like Itachi AND sasuke? They lived their life on the battlefield daily. FYI Itachi didn't kill Shisui and Sasuke didn't kill Itachi. It was all a mind game but they still got their MS's. SO YOU DONT HAVE TO KILL ANYONE.
************************************
I know Itachi said that, but it's not stated in way that makes me think it's 100% canon. I feel like an Itachi's assumption, rather than statement. I could be wrong, but I said I wasn't sure on this one.
We are both assuming then. No arguement here.
**************************************
1 MS + 1 normal sharingan to sacrifice is no advantage over 2 full powered MS. I feel like my responses are pretty clear on that.
Like you said, his S/T technique is very special to him. He would probably never take it out. So why keep in one MS if you cant do Susano'o or risk getting the one MS (or S/T Sharigan) sealed using Izanagi? Of course he wouldnt wear them. He also has the risk of overusing the MS and it getting sealed, "losing the light".
*********************************
Who knows, but not showing the form of his MS is one thing, but making it like it doesn't have one is completly the opposite. There aren't enough facts to support your theory. Mine, which is the opposite, is flawless, the only thing it doesn't really fit is the subjugated Kyuubi's eyes and the ability to do it. We can also add how a normal sharingan could perform ST techs, who knows.
Your arguement is FLAWLESS???
With Manga support? OK. Please show me Manga support that PROVES he doesn't have MS. Maybe you want to bring up the fact that he could control the Kuubi? Oh yea, that supports my theory. Or the fact that he is doing S/T techniques with a regular Sharigan? Oh yea, that helps my arguement too. So exactly how the hell is your counter arguement FLAWLESS lol.
If anything, you have YET to "prove" (with or without the Manga support) that Tobi doesnt have MS. My arguements are STRONGER when we refer to the Manga than yours. If not, please elaborate. I only hear more theories. You cannot disprove theories with more theories. FYI
1. Control Kuubi
2. S/T Tech
3. Itachi says so
