Would obito be the strongest if he didnt gave hes left eye to kakashi?

[Gdamon]

he would be unstoppable...

able to warp himself, his enemies (close range) and (long range) into another dimension...

 

[Nous]

Yes unless his eyes can go blind - if they can, he would be out in a day. Also, according to a widely accepted hypothesis, he would have Susano'o and knowing Obito, he would perfect it.

 

[Almighty Ra]

He would be a serious threat and to be honest Kakashi would probably be unknown

 

[vasu 32]

Well let's see,
A close range kamui to make himself warp and intangible making it impossible to touch him.[ultimate defence]
A long range kamui to warp his enemies in instant without need to touch them.[ultimate offence]
All that and not to mention he has hashirama's dna...well u know the rest.
MAY BE HE COULD HAVE EVEN AWAKEN HIS OWN RINNEGAN AND EYES SWITCHING ABILITY LIKE MADARA,CONSIDERING THAT MADARA SAID THAT THE TRUE POTENTIAL OF SHARINGAN CAN BE AWAKEN ONLY IF U POSSESS BOTH THE EYES.

HE WOULD HAVE SURPASSED MADARA AND WHO KNOWS EVEN HASHIRAMA.

 

[Draphsin]

Yes, he'd be absolutely invincible

 

[adeshina365]

He'd be literally invincible.

Being able to stay "intangible" and being able to snipe with a long ranged Kamui at the same time is ultra-OP.

 

[TenthHokagexRamen]

He would be godly strong.

 

[Slugger]

Meh, nothing special about him. Take the Zetsu from his body, give the eye back that kakashi has and he would still be a crippled old little runt. Take away the Jins and the rinnegan and he is nothing. Most of him was tossed together like Frankstein.

 

[Sol Uchiha]

He would be too OP...
