Tailed Beast Copying Seal

Appearance
This Fuinjutsu Seal rests upon Athos' back, covering most of it. It spreads in a large circle that bubbles out nine times, each one evenly spaced apart from the other. Countless Kanji that seemingly mean nothing are within two thick lines that make the circle, surrounding each circle as well.

Creation
This seal was created by Athos with the help of the Six Tailed Slug, Saiken. It took countless attempts and fails before a working formula was created but thanks to the hard work of both, it came together.

Usage
This seal acts almost like a copy machine, learning and copy down the chakra signature of a Tailed Beast. After the seal has had enough time near the Tailed Beast in question, one of the circles becomes filled with the Kanji for the Beast's name by how many tails they have. Once the seal 'copies' the chakra of a Tailed Beast, this allows Athos access to it. What this means is that by pouring his chakra through the seal, he can produce chakra like that of the tailed beast he has copied. This lets him change his chakra presence completely but, of course, this would also cause him to be seen as a Tailed Beast and put him in harm's way from any greedy hunters.

But that isn't all the seal can do. While Athos can learn a beast's chakra signature from spending time training with the Jinchuuriki, or even mentally meeting the beast with the host, there is more to it than that. By mastering a Tailed Beast personally, there are a certain set of skills that the man can gain access to. Thanks to the intimate relationship Athos forms with a beast when he gets their chakra completely in sync for mastery, he gains access to more than their chakra signature.

Creating this intimate bond and having the seal remember the ins and out of the Beast, this allows Athos to create his version of a Partial Transformation, even without the actual Tailed Beast inside of him. This goes for the forms of the cloaks, as well as the real partial transformation granted to host. Of course, using forms like these causes Athos' chakra to burn up faster than usual and when compared to the might of the actual Tailed Beasts, they are obviously superior. But this doesn't stop Athos from, quite literally, being a Tailed Beast without the need of an actual Beast.
