You would assume that the power of being “just ordinary guy” wouldn’t signify all that much in a mystical world like that of “Naruto.” But you’d be mistaken. Every other shinobi under the sun can summon huge frogs, have a primordial chakra-beat locked inside them, or have a strange eye that takes you to a mental dimension of sheer anguish, but Might Guy still manages to get by using only his own two hands.
Guy is the top Taijustsu (martial arts) expert in the Hidden Leaf Village and serves as Rock Lee’s sensei. In spite of hardly ever performing Ninjutsu (practical ninja magic) or Genjutsu, he has an equal win-loss record with Kakashi, who possesses one of those amusing eyes stated before (illusory ninja magic). Additionally, during their battle, Leaf Village co-founder and “God of Shinobi” Madara Uchiha proclaimed him to be the most skilled Taijutsu practitioner ever. Guy was actually one of the very few individuals in the entire globe who might even pose a threat to Madara.
Guy, however, doesn’t have to rely solely on Taijutsu, unlike his protege. He demonstrates his full capacity for Ninjutsu and Genjutsu on his very first appearance in “Naruto” Episode 21. This truth is sometimes taken at face value, but in actuality, it begs the question of why a gifted ninja like Guy would ever choose to set boundaries. Guy, though, has a special affection for Taijutsu for a number of significant reasons.
Guy wants to inspire his favorite student
Guy is an eager beaver, that much is clear. You can’t help but like the man’s upbeat outlook because he works so hard to assist his students become the best versions of themselves. Lee is Guy’s personal favourite, even though he adores all three of his students—Neji, Lee, and Tenten—in equal measure.
Lee is only capable of using Taijutsu, as was already revealed. Lee endured a lot of bullying from other pupils at the Academy because of his disabilities. Guy was moved by the young man’s plight when he saw this, and he quickly took the youngster under his wing. Guy might be purposefully neglecting his ninjutsu abilities to demonstrate to Lee that Taijutsu is still a viable alternative, as noted in a CBR article.
It really doesn’t require much mental effort to realise this. Lee has always wanted to master solely Taijutsu in order to become a great ninja. Knowing how devoted he is to his pupils, especially Lee, Guy ceasing to use other jutsu would not be out of character. However, there are other plausible explanations.
Taijutsu is in Guy’s blood
It took a while for fans to learn anything about Might Guy’s past, but Guy went through his own tragedies as Kakashi was learning about his ties to Obito Uchiha and Rin’s passing. He had trouble learning Ninjutsu and Genjutsu as a young ninja, and it didn’t help that his dad was seen as a bit of a loser. Might Duy, Guy’s father, was a master of Taijutsu (pronounced “death,” and sure, it is prophetic). He wasn’t quite as successful as his son would be, and because of his failure to advance in the ninja ranks or even complete simple tasks, he was given the appellation “The Eternal Genin.” But he trained constantly and gave Guy all the knowledge he could.
After a young Guy is cornered by the fabled Seven Swordsmen of the Hidden Mist, we witness Duy ultimately turn out to be valuable in “Naruto: Shippuden” Episode 418. Duy, who knew he was going to die anyhow, activated all Eight Gates to save his son, briefly taking on the form of a Taijutsu beast to provide Guy some much-needed escape time.
This reveals to us that Taijutsu is Guy’s family tradition as well as his passion. Guy would risk his life in a similar way as Duy by opening the Eight Gates during his battle with Madara. Even though he actually made it through the ordeal, it is clear how important he felt about leaving a legacy for the next generation by his commitment to live and die by Taijutsu.
