The Naruto show goes through a ton of instances of power scaling, a term in anime (especially Shonen anime) that refers to determining a character's power by comparing them to other characters. Specifically, this is often a power race between Naruto and his rival, Sasuke.
Near the end of the series, Naruto and Sasuke get a massive power boost. In this case, for Naruto is finally can win over the heart and the chakra Nine-Tailed beast imprisoned inside him by his father, and bond completely in a symbiotic synchronicity. The nine-tailed demon fox, Kurama, has learned over time the value, loyalty and determination of the human being he is locked inside and decides moving forward that Kurama is now on Naruto's side, creating a new power blend resulting in the Kurama Link Mode. Naruto is now surrounded by a yellow-orange chakra and black outlines surround him to show how completely enveloped by Kurama's chakra. In this mode, Naruto has incredible, previously unheard-of power. He can also create clones with insane power and throw on chakra cloaks to an entire army. It's a lot!
This special figure release is amazing and a bit of a holy grail for me. It was NOT cheap to acquire and yet it's a pretty awesome version of Naruto while not being a repeat of previously produced Naruto versions in the line (I'm looking at you Sage mode!)
