1. don't fuss, everything Madara says is valid and he can say what have ever he wants/how ever he wants :yeah:
2. the "90 % of his power" thing is far from accurate and don't try too hard, no one would be left with power using that logic.
3. he was dead so that time doesn't count, he intrusted Obito to do the work but, he failed.
4. don't fuss :heh: Madara is above all them weaklings.
Ok I see what you're trying to do keep in mind people are actually reading what you're typing and it even on the surface, without reading, doesn't look like a logical argument.
1. I'm not fusing just stating facts. Everything Madara says is valid but at the same time doesn't make sense. Yes it took Obito years sense he was a child to obtain the tailed beast which is pretty impressive considering this was madara's goal ever sense obtaining his brothers eyes and reading the ancient tablet. A goal in which Madara still has not accomplished. He's still not the 10 tails host. So yes he can say what ever he wants just like anybody can but it just makes him look bad because the 90 plus years that he was alive he didn't accomplish anything.
2. Actually it does make sense because before he even obtained his brothers eyes he was just a blind Uchiha. I was being generous in giving Madara the credit of having 10 percent of his own power because Madara shouldn't even be able to see right now. And actually there are quiet a few people who would still have their main abilities without getting it from SOMEONE else. Note that I said someone and not some tree. Because look at it this way if you take away the power that cakara came from to begin with then there is no series. However it is totally lame to depend on other people's cells to obtain power and to have to use your younger brothers eyes to obtain durable power just makes madara a fodder who steals power he's no stronger than Orochimaru base without experimentation. I only say he has a chance against Oro because he has genjutsu on his side but as I said before without his brothers eyes he doesn't even have vision. Just look at Obito his main power that kept him alive for so long is Kamui a power that naturally comes from his sharingan.
3. He livedto be over the age of 90 after his fight with Hashirama. He didn't in trust Obito with anything he tried to use Obito and failed miserably. Obito ended up doing what Madara has yet to do and become the 10 tails host. Madara however is getting beat miserably even to this point. If he doesn't at least become the 10 tails host which if he did would be an over kill he will look even worse.
4. Madara is actually probably the weakest Uchiha if you think about his sharingan and what it could do the abilities of Obito Itachi Shisu and Sasuke are far stronger than Madara's natural MS sharingan.
