minato couldn't beat every character in the manga, especially those that can fly, but he can 1shot most strong ninjas, including hashirama and edo madara with ftg. it's unclear why he thought it was nessicary to use the 9tails power to defeat obito after he completely trashed him. minato is broken and is at least top 3 but I think he's the best.
not including feat characters like so6p or prime hiru
