No. Itachi Uchiha is.
Madara does not want to take Sasuke's Mongekyo sharingan. Madara wants to create a new world were everyone can live in peace, but the process isn't in a good way.
idoshen, known as Idoshen Uchiha, is the brother of Madara. He is also the father of idashi uchiha. Idoshen was truly killed by his older bother madara. but rencarnated his powers in to his son known as idashi madara has only about 10 percent of his sharingan. basically idashi has two sharingans his own and his fathers.
no he was hit by ameratsu which itachi imparted to him when he touched sasukes head. yes he tried to warn him but sasuke wants revenge on leaf and using madara best way. also i believe he kept he brothers words and it checking out madara before taking him on. waiting for the right time. otherwise madara would have killed him.
No
i believe the whole fight is in the episodes of 128 to 135
He didn't become Madara, he is Madara.
annoyance , big scene , big stink , bother
Really good!
He doesn't have one.
Sharingan
Suaskes (?) If you're talking about Naruto, Sasukes parents actually get killed by Itachi (Sasukes older brother)
If I am correct, Sasuke is his great great (etc.) nephew or grandson. But you should check another website first, because I'm probably wrong. :3 Hope this helped! :)
