Naoe Kanetsugu

Naoe Kanetsugu is a character in the Sengoku BASARA series, who has never been playable in any of the games.
Kanetsugu serves Uesugi Kenshin, the leader of the Uesugi clan. Kanetsugu is portrayed as being very clumsy and sees himself as a powerful and great man. Kanetsugu's famous line, "ORE WA MUTEKI!!!!!!!!" or "I AM INVINCIBLE!!!!!!!!!!!" has reached meme status among fans, and it spawned a nickname for Kanetsugu; "Muteki-Sama".

In the anime adaptation, Kanetsugu appears on episode 5 and 12, the latter being a cameo at the start of the episode. In episode 5, he rode towards Tadakatsu and jumped to his face to attack him, but he was sent flying by Tadakatsu very shortly afterwards, shouting "I'M DEFEATED ALTHOUGH I CAN'T BE DEFEATED!?" as he flew.
