Today we are taking on the most badass character in this game my favorite Yoshimitsu
Yoshimitsu is the leader of the Manji Clan, it's a group that takes money from dishonest rich people for the poor other than that we don't know that much about him we don't know his name, specific age, where he's from or even what he actually looks like since he wears armor covering his entire body we also know that he is a friend of Dr. Bosconovitch who's brilliant scientist specializing in robotics and Bryan enemy because he eliminated some of his people after received perpetual generator.
Manji Clan is of course specializing in Ninjutsu which seems to be a supernatural martial arts style in itself as Yoshimitsu is able to teleport, become invisible, create clones and in Kunimitsu's case even breathe fire, Manji Ninjutsu also uses impossible spins and stances with the use of specific weapons and Yoshimitsu fightning style is based also on Kenjutsu and Battoujutsu and he also had Manji Jujitsu so i guess Yoshimitsu fightning style is one of most impressive in entire Tekken universe. Yoshimitsu also has other powers and supernatural abilities besides his fighting style he can also heal himself using his two stances such as Meditation and Indian Stance which he can most likely heal really serious injuries. Yoshimitsu also uses poison breath from his mouth and can also copy someone's movements as well as nullification some techniques it's also worth mentioning his mechanical arm thanks to which he can rotate an object such as a sword with enough speed and precision to even fly but most important thing about Yoshimitsu is definitely his swords.
First of his swords is called Cursed Blade Yoshimitsu it's a demon slaying weapon that wants blood and which sometimes causes Yoshimitsu difficulty in controlling it but sword obviously increases user strength and gives him another abilties. Most likely thanks to the sword he also has some control over the opponent's soul because he can suck the life force out of the opponent and heal himself. Cursed Blade Yoshimitsu also gives off a powerful ominous red aura that is used for both attack and defense and at times appears to be purple suggesting that Yoshimitsu uses even more powerful attacks (which could most likely be related to Azazel as Yoshimitsu is able to sense Azazel's power through his sword and Azazel emanates a similar aura) so it seems to me that this sword alone is much stronger than most ofTekken roster characters.
His next sword is a sword called Fumaken apart from that not much is known about him but he also has sealing ability like Yoshimitsu using this sword to sealing power of his first blade to attach his desires.
So Yoshimitsu has supernatural fighting style and 2 magic swords i don't see why this guy should struggle fight with normal tournament participants when he can literally pull the soul out of character. In my opinion Yoshimitsu should be much stronger than Bryan who only has a perpetual generator and uses kickboxing (in fact Bryan often has weapons during fights with Yoshimitsu such as a laser or a minigun but he doesn't use them directly in the fight) and in fact is a cyborg but compared to Alisa and Jack much less modified and only upgraded by Dr. Abel who is inferior scientist compared to Dr Bosconovitch and Bryan life was coming to an end so he was probably a failure.
As for tier then
Normal Mokujin - Yoshimitsu according to canon events
Silver Mokujin - Yoshimitsu according to myself
In my opinion Yoshi should be strong enough to face Base Mishima family members on equal maybe even stronger if he fully controlled Cursed Blade Yoshimitsu considering that his sword may have a similar origin of power as Azazel who is also able to compete with them his sword can also be effective on Devil Gene since Cursed Blade Yoshimitsu is a ''demon-slaying weapon''
Normally Yoshimitsu is comparable to Bryan who despite being strong is rather inferior to people like Paul and I don't think he deserves top tier for now Yoshimitsu also loses to Anna in Tekken Bloodline which would put him on high tier at most since Anna is at most comparable to Nina who is definitely high tier.
