Why is minato using the other half of the Kyuubi's chakra?

[Fuxion]

It's not like there in the middle of battle against the strongest person since the sage or anything...........

minato and naruto will form a fusion . naruto will obtain the intelligence , ftg sealing technique of the fourth and the half of kyubis chakra.
they will be called miruto or narunato

Ohhh u guys dont get it do you? There is a difference between having UNLIMITED chakra and STRONGER chakra.
The kyuubi chakra indeed gives Minato a powerup, just like naruto got much faster and stronger after mastering kcm, Same goes for Minato. -.-"

For example: If naruto punches in normal form the punch is not as Strong as in kyuubi form or sage Mode form.

There is a difference between having chakra Reserves and chakra Level.

He better give it back soon because there's a raging Juubito after his son, lmao

OT: Minato had to be in KCM to be in the other 3 kage's power levels for the barrier, that's it.

Hashirama went sage mode for the barrier :/
But i guess he is doing the bulk of the work
