Susanoo is not HUMAN..it is a Technique using the mangekyu Sharinggan..TsUkoyumi+Amaterasu= SUSANOO..
Susanoo's Amaterasu - Susanoo is Huge Skeleton , a jutsu created by itachi sama using his sharingan
I would say that Chibaku Tensei is stronger. But it depends on what size it is. If the size was as big as nagato's chibaku tensei, than susanoo might be strong enough to escape the gravitational pull. But if it was the size of the sage of six paths (which was the size of the moon) than susanoo would have no chance of escaping the gravity.
Shimane Susanoo Magic was created in 2009.
No.
The strongest susanoo is believed to belong to Madara Uchiha, as he was able to manifest a Complete Body Susanoo with two additional humanoid arm-like appendages in the manga series Naruto. This version of Susanoo is considered exceptionally powerful due to its immense size, durability, and offensive capabilities.
In Shinto mythology, Susanoo's wife was Kushinada-hime. She is known for being rescued by Susanoo from the eight-headed serpent, Yamata-no-Orochi.
Any color
No way, Ameterasu would be absorbed by preta and so would Susanoo! Or Deva could crush Sasuke with Chibaku tensei or tunnel through Susanoo and rip Sasuke's soul out with Gedo Mazo.
He is sealed inside Susanoo.
he did not stop them
Actually Susanoo is a technique of the combined Tsukuyomi and the Amaterasu in the eye of Sharingan in Naruto world. I dont think he had son in Japanses Myth.
