 * Without alien ancestry, non-transmigrants
 * No kekkei Genkai
 * No jinchuuriki
 * No gifted or stolen powers

Now that's an interesting debate, because only ordinary humans are taken into account. My candidates:
 * Might Guy
 * Jiraiya
 * Minato (alive, thus non-jinchuuriki)
 * Third Raikage
 * Hiruzen

That's exactly what the topic is, except for the kekkei Genkai part wich i don't think should ruled out since you are born with it. Going on with the last, Itachi is definitely a good shout, as well as Third Raikage and Hiruzen.
