Why Naruto Bijuu Mode Is Different

But if you watch the scene right before that he says.

Naruto y boruto rasengan. Since the 8 trigram seal only leaks the chakra out into naruto and not the whole bijuu itself. His pupils becomes slitted the whisker like markings on his face become thicker to resemble the trigram and the chakra shrouds shape alters to resemble a full length haori similar to the one minato usually wears. When naruto is in level 2 bijuu mode you see the cloak of chakra his hair and the black markings all over his body make him look a lot like rikudou sennin did.

The users eyes become orange when in this mode and whereas the demon fox cloak is red and releases chakra as boiling bubbles this forms shroud is yellow and releases chakra as flickering flames56 while in this form narutos chakra signature and smell are different as noted by neji hyuga and kiba inuzuka respectively7. And attempts to go from kcm to kurama mode to bijuu mode. Why narutos bijuu mode is different.

Minato uses the same form and hes a sage and if we look at madaras six path form vs obitos six path form we see that madaras is more energy based like narutos where obitos is more beast like. You can see in the last naruto fights toneri using normal sage mode combined with bijuu mode hence why he has the pigments around his eyes rather than using six paths sage mode. My personal headcanon is that its a heighened biju mode naruto enters because hes a sage.

Its meant only for the chakra to leak and mix with narutos chakra. However hes low on chakra so the transformation doesnt complete and he sputters back to base. Thats why we never see naruto transform into a full on kyuubi like other jinchurikis do.

Also the reason for narutos bijuu related abilities being different from other jinchuurikis its because he does not possess all of kurama inside him. When naruto fought kyuubi 9 tails episode 240 250 while he was training with killer beethe 8 tails jinchuriki he gained control over the power of 9 tails this came to be known as the kyuubi chakra mode of naruto or kcm naruto but he wasnt proficient in using it.
