Tenma looks cool, but what's his greatest feat?
To elaborate Laciel and Redgrave's answers :
Yato managed to hold off Hajun (most OP being of masadaverse) for 8000 years. Hajun is Hadou god with taikyoku that increases every moment thanks to infinite feedback loop between him and his 'brother'.
every hadou god has taikyoku as source of their power. fight between two hadou god determined by taikyoku value. taikyoku value of 2 will always win against hadou with taikyoku 1 and so on.
taikyoku is source of everything, it exist before and beyond dimensional structures. it is unity before duality, automatically granting hadou Transduality and true-godly regen by default, even for fodder hadou who only have Taikyoku value of 1.
there's beyond-dimensional object called throne, it is a baseline 1-A thing which encompass all creation. hadou god with taikyoku value of 1 can destroy it easily.
and Tenma Yato have Taikyoku value of 100. basically second strongest hadou god in the series. right behind Yato would be Reinhard, Mercurius, who have 90 taikyoku value each.
as I already said, hadou of higher taikyoku value will always be able to overpower weaker one. said 'weaker one' will also have transduality + true-godly regen. Mercurius defeated Satanel who have Taikyoku value of 80, hence, Mercurius can bypass other character's transduality and true-godly regen. and Yato is stronger than Mercurius. so its safe to say Yato might also be able to bypass other characters' true-godly regen.
not to mention Yato have 1-A subordinates, his legion. Yatsukahagi. but I can't remember all of their abilities. (though, Yato sacrificed them to increase his Taikyoku iirc)
Yato also has time armor, powerful defensive ability which can stop time even on place with no concept of time (outerverse). time armor is also the ability which allows Yato to survive Hajun's assault (you know, the hadou god with infinitely increasing taikyoku), granted, that was because Hajun did not even notice Yato at all, but its great feat for Yato nonetheless, to stop Tengu Dou (Hajun's Law) from completing.
But yes, if its 'True Nya', I don't know wether Yato can bypass Type 5 Immortality or not. outer gods/the archetypes are beyond all perspectives, thus they are literally immutable after all (see everything as eternal unchanging whole).
