Minato Namikaze's Jinchūriki Forms

When Minato Namikaze used Dead Demon Consuming Seal on Kurama, he sealed himself away along with the Yin half of its chakra, thus becoming a pseudo-jinchūriki. After his reincarnation, he managed to control it, impressing both his son and the fox.

Nine-Tails Chakra Mode
Once he was reincarnated, Minato was revealed to be able to use a chakra cloak similar to those of Naruto. When used, it holds resemblance to something in between both; while predominately looking like the Nine-Tails Chakra Mode form, Minato's shroud also does have the additional seals that appear on Naruto's hands and feet and additional magatama design on collar while in Tailed Beast Mode. The bangs at the sides of Minato's face go upwards in this mode as well.
