What if obito has multiple personalities because he possibly merged with zetsu when dieing. Every time a body part gets hacked off, it looks like a squishy zetsu-like substance. I know that the playful tobi was supposed to be a disguise, but maybe it was a different "person" and now this demented evil tobi is having his turn.
Lol this is just a joke, but thatd be hilarious if it were true
Unfortunately i do understand how it could be obito, it just doesnt really seem to be good enough of a reason. Of course tomorrow will begin our understanding as to who or why this is.
I do still believe oros hand is in this somehow, be it on purpose or his research aiding in this thing that we call tobi.
LOL what if this series is a mega troll story and its just the sage looking into the future to see how things would play out if he separated the 10 tails.
Its a story written by a jiraiya esque loljk
