Dey clearly hav 2 different sharingans, im tellin yaw its either da 1st hokage son, da sage of da 6 paths son, or jus a new character. 1 guy said he thinks dat madara wuz goin 2 villages gettin talent an he picked tobi an da gold n silver brovaz thas 1 all of dem fought hakages madara fought da 1st, da gold n silver brovaz fought da 2nd, an da 4th wuz more skilled than da 3rd so tobi figured let da 9 tails fight da 3rd an he will take care of da 4th, da 9 tails iz da only 1 dat failed in gettin rid of dem bcuz i still think madara had sumthin 2 do wit da 1st hokages death. PS:how does madara know da 1st iz dead if he supposely died b4 him. i kno he wuld be old az shit, but cum on now he knows he iz dead bcuz he killed em himself. but a reason y it culd be da 1st hokages son iz bcuz da 9 tails already knew em an he culda known him since birth considering da 9 tails an da 1st hokages child wuz inside of his wife. also he has da same skin color az da 1st an he probaly iz more on madaras side instead of his possible fathers bcuz he probaly feels neglected or abondoned by his father or maby madara raised him as his on or maby da 1st hakages wife cheated an madara iz da real father, also i wuld like 2 add dat his name culd hav been tobi bcuz he culd hav been named tobi after his uncle tobirama(2nd hokage). or maby he iz jus a new character dat wuz bak wen kakashi an dem were kids it jus neva showed him but it will show flashbacks of wen dey knew him. idk but i personally think tobi iz sumbody who looked up 2 madara an wuz secretly trained by him bcuz dey both had da same intentions, like think about it, neither 1 of dem were really bad or had bad intentions dey jus had good intentions but doin sumthin about it in a wrong way, madara only feared 4 his clan an he did sumthin about it by trying 2 kill da hokage, tobi wants a perfect world with no lies an erybody culd be equal, an he has 2 take all da tailed beasts 2 do dat an at 1 point nobody wanted da tailed beasts but now their protectin em, which part of dat iz bad. biut im tellin u madara even knew who tobi an nagato wuz. him an his main prodigy tobi had all dis shit planned out madara must not kno tobi iz about 2 get da 9tails bcuz he said he iz cumin 2 get it. so az soon az him an tobi be on da scene 2getha its ova 4 naruto an dem. an by dem i mean whoeva want dat shit wit da 2 strongest uchihas of all time, dat iz if tobi iz 1, which i believe he iz if he wuz 2 be believed az madara, it also culd be his son if u think about it, but dats really my guess lemme kno wat yaw think
