Karla verse

The Shredder is a slim, but tall, brawny, and toned Japanese man with shiny, chrome plated armor on his chest, shoulders, arms and lower legs, worn over a maroon outfit with a dark blue cape hanging over his back. His signature helmet, the Kuro Kabuto, is perhaps the most notable aspect of his appearance and it covers up his face because it was partially burned and disfigured, such to the extent that he has very little vision left in his right eye. he uses customized, partially mechanical ones built into his gauntlets. His armor is also larger and bulkier though it's streamlined and smooth at the same time. The spikes on it are larger, longer and more blade-like than most previous versions. As previously stated this Shredder suffers a serious, disfiguring burn on the right side of his face; a considerably greater injury than the scratch marks (from Splinter) most others possess that leaves him nearly, or completely, blind in that eye.

The Shredder's immense capacity for hatred seems to stem from an inability to accept his own failures, misfortune and mistakes. Instead he seems to need somebody to blame everything on; shown when he accuses Splinter for Tang Shen's demise, despite he being the one who initiated the assault that took her life, and accusing him again for Karai's mutation, despite having put the girl in danger in the first place. Saki is utterly convinced that Splinter is the cause for all the suffering and misfortune he endures, and considers anyone linked to Splinter to be just as guilty. And he believes that anyone who has contributed to his misfortunes should pay with their lives.

Oroku Saki was born in rural Japan into the ninja Foot Clan, the longtime enemies of the Hamato Clan. After a particularly devastating assault by the Hamato Clan on a Foot Clan village that left the rival ninja clan in tatters, the baby Saki was discovered amongst the wreckage by Hamato Yoshi's father. He was then adopted by Hamato Yuuta and raised alongside Yoshi as brothers; and greatest of rivals, with Oroku blissfully unaware of his true heritage. their rivalry escalated when they met Tang Shen and subsequently fell in love with her. Saki had been with her initially but she broke it off in favor of Yoshi who she went onto have a child with and their bids for her affection turned their rivalry into hatred and Saki insulted Yoshi in front of Tang Shen, and in response was attacked by Yoshi. This brief fight ended in victory for Yoshi, while Saki fled and wandered alone. During this time Saki learned of his true heritage and rebuilt the Foot Clan and donned the moniker 'Shredder'.
