Mr. Chi is a walking CMOA, and causes others to have them with his mere presence. Before his existence is revealed the mere notice of him taking part to the Pan-Asian Wrestling Tournament makes Baba fear for Tiger Mask's life. Then Baba tells of the one time he saw him, when he sneaked in a Battle Royal and curbstomped all the wrestlers, and admits he's stillutterly terrified of the guy in white pajama and turbant. And that was just the beginning.
He decided to test Tiger Mask in his hotel, and fought Kintaro Oki (one of the strongest wrestlers of the time) wearing his mask as a joke: Oki managed to hit him with his super-powerful headbutt, but then got defeated when Mr. Chi performed a Nonchalant Dodge (on one of the strongest wrestlers in the world!!!) and let him hit a mirror and the wall. I repeat, Mr. Chi defeated one of the strongest wrestlers in the world with a Nonchalant Dodge.
Mr. Chi had announced he had understood how to defeat the Super Tiger Drop after seeing it once. When he fought Tiger Mask, the latter realized he was losing and tried the Super Tiger Drop... Only for Mr. Chi defeating it by grabbing the ring ropes. He defeated a move that had killed a bear and made it look easy (to be fair, once you think of it it is easy. But first you have to think about it, something that some of the finest technical fighters of the series had failed to).
Oki's moment came in the fight between Tiger Mask and Mr. Chi. When it looked like Tiger Mask was completely defeated, Oki told him his secret strategy to win: faking an headbutt, then when he defended from the headbutt grabbing his legs and throwing him on the ring's poles before using the unescapable submission move Boston Crab. Tiger Mask didn't expect Mr. Chi to fall for it but tried it anyway out of respect... And worked like a charm. Oki then smugly told Tiger Mask that he did hit Mr. Chi with his headbutt once when he was wearing his mask, and never used it in the tournament to let him believe that Tiger Mask's headbutts were obscenely powerful and make this entire strategy possible.
After being defeated, Mr. Chi unmasks himself and gets two Moments of Awesome in one instant, and makes all of his previous Awesomeness even more Awesome: taking off the mask he not only reveals that he's over seventy years old (he wore the mask and his long-sleeved outfit specifically to hide his age), but that his true identity is The Great Zuma, in-universe the greatest wrestler of all times that could defeat the reigning world champion in ten seconds in his thirties and had remained undefeated until that day. Tiger Mask then realized that yes, he had just defeated an undefeatable wrestler, but if that undefeatable wrestler had been any younger he would have been defeated.
Also: Oki had successfully outsmarted the greatest wrestler of all times, who had decades of experience in the ring and as a teacher in his bag. Nobody else, either before or after him, was ever able to brag about something like this.
Final awesomeness: he had returned in the ring to teach a lesson to the Heel wrestlers that didn't know how to actually fight, and, before about one hundred thousands people, bragged that they had fallen like children when faced with the strikes of a seventy-years old man.
Tiger Mask versus Dick The Bruiser at the World Heel Tournament. Bruiser tried some of the worst fouls in the story (including setting the opponent on fire), and Tiger Mask not only neutralized them but actually won by perfecting them on the spot and using them on Bruiser.
The final fight of the series was Tiger Mask versus then reigning NWA World Champion Dory Funk Jr. The best fight in the series by a long shot.
Tiger Mask's on ring Heel-Face Turn. Asked by Ruriko to give a good example to Kenta, he decided to fight fairly in spite of facing Black Python, Tiger's Cave first assassin. Then, when insulted by the public and mocked by Python for it, shut everyone up by performing perfectly the back suplex, a very powerful and very difficult move that won him the match and literally left everyone speechless.
The first match between Tiger Mask and Miracle 3 was one for the latter because he managed to counter the Fujiyama Tiger Breaker in a way that nobody could possibly see coming (not even Tiger Mask, who had actually humiliated three other counters before that). Then the rematch was one for both due the sheer skill showed in the first round, but mostly for Tiger Mask when he showed the Tiger V and revealed that Miracle 3 actually was three different wrestlers, two of which he had utterly defeated.
The very first of the story is when Naoto pays the debts of the orphanage with the money he was supposed to give to Tiger's Cave. He knows he'll die for it, and is terrified of what will happen to him, but he does it anyway. And took the chance of insulting and mocking a Yakuza boss, who didn't react because he was scared of him (and likened the experience to facing a dangerous and desperate tiger).
At the Maskmen World League Lionman has a moment of pure awesomeness when Mr. X makes him show off his strength, and he crushes a completely filled case of cokes and wins a tug of war with twenty people lured by the promise of tickets near the ring if they won. Then the moment of awesome is hijacked by Giant Baba, who, masked as Great Zebra, yanked the chain of the tug of war and matched Lionman's strength with one arm.
Generally, Great Zebra's performance at the Maskmen World League: where even Tiger Mask had to use fouls to keep up with Tiger's Cave wrestlers, he knocked down Egyptian Mummy with a single chop and utterly owned Lionman by choking him with his legs as Lionman tried to use a backbreaker on him. Made even more awesome because of Lionman's reaction to Great Zebra arriving to kick his ass was a terrifiedBig "NO!", while he considered fighting Tiger Mask (who was the best pupil in Tiger's Cave history, hence why Lionman himself had given him the mask of the tiger) as easy, if a little tricky.
Earlier in the tournament, Mr. Shadow and Skull Star had used a Mr.X-caused black out to attack Tiger Mask together, but their tactic had been exposed by Kenta, who Mr. Shadow punched for the trouble, hitting our hero's greatest Berserk Button. What followed was the single most terrifying attack ever used by Tiger mask, showing exactly why he was considered Tiger's Cave greatest pupil.
Tiger Mask versus Mil Mascaras. It's not seen, but sport journals say that it was one for both: in the first round, Mil Mascaras dished out a Curb-Stomp Battle through sheer speed, technique and strength (it's noted he unleashed a very long series of dropkicks), showing us why his Real Life counterpart is hailed as one of greatest wrestlers in history; in the second round, Tiger Mask successfully executed the still unnamed Fujiyama Tiger Breaker, winning the round and weakening Mil Mascaras to such a point that only the weakness from recently surviving Tiger's Cave illegal fighting ring prevented Tiger Mask from slapping him down and winning.
Speaking of Mil Mascaras, there's Tiger Mask match against his younger and bigger brother El Sicodelico in the World Heel Championship. El Sicodelico is just as capable as Mil Mascaras... And yet, this time, Tiger Mask is holding his own, and it's not until Tiger Mask fails the Tiger V due a wound in his previous match that Sicodelico gets the upper hand. Then Sicodelico starts committing fouls... At which point Tiger Mask feels free to show what Tiger's Cave had taught him. Curb-Stomp Battle barely describes how easily Tiger Mask won.
