*I begin by performing the Horse → Tiger; after which I then begin to inhale as much air as I can, and begin to gather my katon chakra in my lungs. I then begin to mould and manipulate the katon chakra; forming it into a large, dense sphere of fire. I then exhale, and by doing this I release the fireball straight out of my mouth. Just as the fireball leaves my mouth, I begin to channel more katon chakra into it, increasing its size drastically; giving it the appearance of a meteor. I then release the fireball and it charges forward away from me!*
Well the technique would burn the opponent severely, and due to its size, the explosion would cover a large area making it harder to avoid.
On the other hand, due to its enormous size, it may obstruct your vision and blind you from an incoming attack from a different direction. Also, since the technique is large, it may take longer to reach the opponent compared to a smaller attack; in which the opponent can use the time to dodge the attack.
