i hope not but if it was happen it would most likely be kakashi with some help from naruto that changes him..the only reason i throw naruto in there is because obito was very similar to naruto when he was young
Obito is going to absorb Iruka and adapt the I at the beginning of his name. Therefore he will think he gains strength, when actually he grows weaker. Naruto will then use talk no jutsu to make Iruka the dominant persona of Ibito, thus converting him to the good side. Excellent, thread, well thought out.
