Alright then. Haku and Zabuza will be able to capture Jiraiya using a combination of silent killing techniques, powerful water jutsus and near flawless teamwork.
Silent Killing:
Being their primary form of assassination, both Haku and Zabuza are highly skilled in the art of silent killing, which involves locating their opponent through the use of hearing alone and taking them down while they are unable to see themselves. Using this in combination with their Hidden Mist technique makes them some of the most formidable assassins ever mentioned.
Kenjutsu:
As the leader of the previous Seven Swordsman of the Mist, Zabuza's proficiency with blades -most notably the Kubikiribōchō- is also one of the best in the series. His blade, Kubikiribōchō, has the ability to repair itslef with the blood of his fallen enemies so that it will never dull. Jiraiya will need to be cautious when engaging a swordsmaster of Zabuza's degree.
Hidden Mist technique:
One of their trademark jutsus that these two use to capture their opponents is using the famous Hidden Mist technique, which is created to allow them to have an advantage over their foes with their silent killing technique. This jutsu is able to cover a large area with a very thick mist that only allows vision directly in front of the user at an extremely close range. This jutsu will keep Jiraiya on the defensive.
Demonic Ice Mirrors
This jutsu is a very useful teleportation technique that Haku can use to attack Jiraiya either physically at great speed or with senbon to attack his vitals using his vast knowledge of the human anatomy and skill at senbonjutsu. This justu can be used to teleport with one one single mirror, or to create a large dome of mirrors that Haku can teleport between at imperceptible speeds, rendering him physically untouchable while in the dome. This jutsu can be used to keep Jiraiya from using summoning jutsus, effectively negating Jiraiya being able to use SM due to the speed in which it can be created and activated. Using this jutsu in collaboration with the hidden mist jutsu will assure that Jiraiya will not be able respond to any of their attacks on him nor will he be able to use any attacks himself.
Its not everything, but think this is decent enough of an opening.
EDIT: I would appreciate it if only me and Shikamaru101 would post on this thread. Also, please note that this is not a stomp thread because the intent of the opponents are to CAPTURE. NOT TO KILL like eveyone thinks in every VS thread.
