Yeah but this means Madara is the biggest emo on the planet whilst also suggesting that in order for the Sharingan to work and grow more powerful being emo is a prerequisite. I would be more interested in knowing why only Hashirama has Mokuton abilities and not anyone else in his family.

While it is clearly fan service, I don't the value of Minato being here. He would not know things which Orochimaru wouldn't know already. Unless of course these four are going to head off in to battle but then even Madara would be way overloaded against this lot.

Also, kind of sad that the only Sannin to have perished is Jiraiya. Which brings up the question; where are the Kages right now? Effectively Naruto has become leader of the Shinobi alliance and Supreme Kage by leading the attack and determining what the army does at this point.
