Just because he hasn't shown it doesn't mean he cant use it, don't forget it takes time to prepare itHas Obito ever used edo tensei? No. He wouldve done it by now if he knew.
LMAO, this is actually quite accurate.Obito should be able to perform a lot of shit, but he doesn't.
Yeah and welcome to the baseIt is likely, but it might not be as strong as when Kabuto preformed it. Then again, he might not be able to use it unless he was planning to since one needs to have a body to resurrect in order to perform the jutsu so that would be a problem. If he did plan on it...well... everyone else is going to be screwed.
Have he used the Rinnegan? No, because neither Madara or Obito needs it right now because they are OP.Has Obito ever used edo tensei? No. He wouldve done it by now if he knew.
