The C2 final was defining for this era of his character IMO.
Okada isn't the stereotypical Japanese wrestler coming to America to work hard in order to make a reputation from scratch - he
knows he's the best professional championship/tournament wrestler in the world and he's offended that anyone, American or otherwise would ever even question that.
He works exactly as hard as he needs to back the claim up. Once the C2 and its belt came to represent that it's been up to his opponent how good the match was going to be... but Okada was going to win.
Speedball brought it like Ospreay did so they worked him into delivering 5* matches, but they both still lost like all the 2* bytches.
