Everyone's born with their soulmate's first words to them written on their skin, and that should make things easy, but it really doesn't. "Roy has alternatively despised his mark and clung to it like a lifeline. Colonel. Just one word, right at the back of his foot. His literal Achilles’ heel."

For a prompt on my Tumblr: TOS!Sannin. Tsunade McCoy the grumpy, compassionate alcoholic with a heart of gold, Jiraiya Kirk the cocky and intelligent leader and womaniser, and finally, S'chan T'gai Orochimaru, the 'non-emotional' genius scientist with a not-so-hidden soft, gooey emotional centre.

An AU oneshot based off of my fic "An Invincible Summer" The Massacre was prevented, and some things stay the same, but a lot of things are different. Mostly that Natsu ends up with a different Uchiha.
