uchiha's inherited the yin chakra
tobirama said that when a uchiha goes through strong emotion a chakra will sprout in their brain and change their eyes
we see this happening here with obito, he awakens ms the special chakra awakens and the side with hashi's dna grows the rods which is yin/yang release-uchiha yin chakra and hashi's yang chakra made rods sprout
which is most likely why kakashi fainted because he cant handle the uchia yin chakra and needed time to control it or something
obito only got one dose of special chakra it sprouted in his eyes and his sharingan became mangekyou sharingan
It's different with sasuke
first of all sasuke is an indra's transmigration
indra had the susano'o
a sharingan capable of awakening susano'o is a rarity
when sasuke awakened his susano'o atsui said it resemble genjutsu
in the genutsu that sasuke's susano'o resembled you see the shadow silhouette of the sage and susano'o
first dose of special chakra
the angrier sasuke gets the bigger susano'o becomes
his hatred has grown giving his body power
another dose of special chakra
his last dose of special chakra
right as he's goes blind he almost has a full susano'o
with obito he had a strong emotion the chakra sprouted and his sharingan became mangekyou
with sasuke he kept getting angry(strong emotion)and the susano'o(special chakra)kept getting bigger his eyes turned into mangekyou but the chakra kept sprouting and instead of his eyes changing even more they went blind so he had to get an ems to counter that
indra had the ems because sasuke had to get the ems to handle his power and when the sage said that madara combined his and ashura's chakra to get his,madara had the ems
