Manny Pacquaio
We don’t think much is capable of rattling Pacquaio. The world’s only eight-division boxing champion endured an upbringing that most people couldn’t imagine. His own father killed, cooked, and ate his pet dog in front of him. Later he’d live in a cramped apartment on the same street as Muslim extremists.

Pacquaio even dropped out of high school because of extreme poverty. Thisa man who has faced extreme challenges but has overcome them all. With his ferocious punching power, humility, and political influence, he’s one of the most unique and inspiring people on this list. He’s definitely useful for the end of the world.
