Kazuchika Okada
Easy pick here, especially if we’re assuming that this G1 is rewarding it’s winner the same prize as always, a shot at the IWGP Heavyweight Champion. If that’s the case, (and it’s my fantasy G1, so it is), then Okada has to be involved. And believe me, if Okada gets through this field as G1 winner, he’s truly earned the right to choose his WK opponent. Hell, if he wins this one, he could pick The Brooklyn Brawler to challenge and nobody could blame him.
