Why Shisui wasn't reanimated during the fourth Great Ninja War? Shisui is one such contender that would have turned the tide of battle in Kabuto's favor. Yet it's quite odd to see this capable Shinobi and Tyleo were looked, while many speculate that it's simply because Shisui fell into the river and his body couldn't have been recovered. The actual reason lies somewhere else entirely. One of the most popular theory is that Shisui's DNA could not be found. Considering Kabuto was able to acquire the DNA of Madara and several other Shinobi that had passed away a long time ago, it makes no sense for Shisui's DNA to be unobtainable. However, in Shisui's case, this explanation is somewhat possible given the circumstances under which he lost his lie. It initially seemed that his body was never found after drowning in the river, though it was later revealed that the Uchiha clan found his body and blamed itachi for murdering him. However, this doesn't quite add up as Kabuto would have been able to find Shisui's body. Another explanation is that Shisui's reanimation would have been useless. The reanimation technique revives the person just as they were right before they died. If Shisui had been revived, he would have been completely useless as both of his eyes had been removed before he died.
