Official Move Approval III

[Omni]

Rasengan-Ha (Physical Strength) (300) – A move that pays homage to Dragon Ball and Dragon Ball Z. Minato takes both hands and places them in a Kamehameha like pose as he begins charging towards his opponent. As he runs at his opponent, Minato forms a Resengan between his two hands as he says the name of his attack, much like Goku would while charging the Kamehameha. The only difference to this is the addition of ‘Ha!’ at the end of Rasengan (Ra-sen-gan-ha!). This move takes 10 seconds to charge, and the charge begins as soon as Minato assumes the Kamehameha-esque pose. This type of Rasengan is also 3x larger than his usual Rasengan, (A result of the charge time). Similar to this

Okay.

Spiralling Flash Super Round Dance Howl Style Three (Ranged, Physical Strength, Teleportation, Hiraishin Kunai) (300) – Minato throws 6 of his Hiraishin Kunai around his opponent(s), he then teleports to each Kunai, one by one, letting off one attack each time he teleports. The aim of this move is to catch his opponents off guard. All though he is mostly limited to simple punches and kicks during this attack, Minato is able to utilize 1 Rasengan during this move. This move is more useful in situations where he is faced with many enemies, such as when he is surrounded or outnumbered. Minato will always aim to get his Kunai somewhere in the middle of the enemy ranks, so that he doesn’t have to move too far to attack an enemy.

This seems like something you could do simply by combining your existing moves. Unless the Rasengan is instantaneous. If it is better in that sense, any downsides?
