Tailed Beast Chakra Arms

Red Chakra Arms is Kyūbi Naruto's down special move in Super Smash Flash 2. Naruto transforms into his Four-Tailed Form and slams his hands into the ground, causing giant arms from underground to pop up and deal multiple hits. This move deals 45% damage, but he cannot use it in midair. In midair, if activated, he will simply transform into his Four-Tailed Form, then change back. Also, the move has a slow start-up and ending lag.

Kyūbi Naruto also uses it as his Grab, which he can easily do in his One-Tailed Form.

Origin
Red Chakra Arms is an ability a Jinchūriki is able to perform when in a tailed beast form. The Jinchūriki will use the raw chakra of the their Tailed Beast to form arms, which they can freely manipulate to attack their foes, able to strike an opponent faster enough before it can react to it.

The chakra arms hands are clawed while the rest of the arm seems to lack any kind of joint, thus allowing them to have flexible movements that will generally be impossible for normal arms. The user can create any number of arms that they desire and they can also serve other purposes such as grappling hooks, to either grab onto objects or enemies from great distances, for offensive means, as merely touching one of these can cause fatal burns, due to the Nine-Tails' seething hatred within its chakra (though this is not always the case). Due to having chakra attached to his body, the chakra arms can grow in size and from the fourth tail up, Naruto, the arms, or any part of his body can divide into two or more fully operational appendages.
