#2 Kazuchika Okada

Kazuchika Okada to me isn't The Rainmaker anymore. He's the Record-Breaker. Coming off of a 720 day reign, 12 successful defences against the likes of Sabre Jr, Katsuyori Shibata, Naomichi Marufuji, Naito, Sanada, EVIL, Cody, Bad Luck Fale, Suzuki, Tanahashi and most notably - Kenny Omega.
He also has the most combined days as IWGP Heavyweight Champion, and Dave Meltzer rated his matches with Kenny and Tanahashi - 5 star plus.
With all these accolades, with nothing to prove as well in the G1 and fans wondering when Okada vs Omega 5 will happen, Okada winning makes a lot of sense.
With Okada only being 30 years old, he has a huge future and with him possibly main eventing Wrestle Kingdom 13, he would have main evented 5 straight Wrestle Kingdoms, showing how much faith the company has put in The Rain Maker.
