[Not joining a crew + beating Luffy + beating Garp + crippling the Marines + establishing his own power + multiple Devil Fruit abilities]

"Lenno, this is an order! Coby is the future hope of the Navy; he cannot be tainted!"

Karp looked at Reno meaningfully, "As his senior, let him take on this responsibility!"

Having said that, he left Leno alone in the dark Impel Down.

"I've been in the Navy for six years! And all the merits I've accumulated are less than what a guy did in two months?"

Leno's sense of justice was completely shattered. What kind of bullshit justice is that!

In his desperate and unwilling state, he awakened his superpower.

After leaving Impel Down, Reno rose through the ranks from Vice Admiral to Yonko (Four Emperors), then Pirate King, and finally became the ruler of the world.

Garp, watch closely!

How can the traitor you personally forced to rebel, now act as a pirate?

Crush your revered naval hopes into dust!

I want to become the grandson of the Pirate King, and I'll die right in front of you!

The justice he upheld his whole life was trampled underfoot!
