Kay. Let's go into the summoning proper. You should remember the default summoning process. You make a blood contract with the bats and then through you sacrificing your blood, you are able to summon the animal. You will imbue chakra, weave several handseals and press your palm against a physical surface to summon the animal.
(Kuchiyose no Jutsu) - Summoning Technique
Rank: B
Type: Defense/Attack/Suplementary
Range: N/A
Chakra Cost: 20
Damage points: N/A
Description:
To summon the creature the ninja will wipe blood on his hand, perform the Boar → Dog → Bird → Monkey → Ram handseals and then touch the ground or another object, where a sealing formula will appear. Though it appears that as long as significant pressure is placed against the blood in some form, the summon will be complete, most summoning uses use a solid surface, though in some cases it can even be done mid air. There can be variations to the summoning steps, some ninja like Temari will wipe blood on her fan, then by swinging the fan the animal is summoned. Other ninja like Orochimaru wipe the blood across a snake tattoo on their arm first, then touch the ground. Others will clap their hands directly like Nagato through the use of his Animal Path. The user must have signed the contract with the creature he wants to summon but the technique can be used to summon a generic creature of that contract (B-Rank) which will have no special traits or abilities beyond those normal to the rest of the animals in the contract. The animal is always summoned on the mark that appears upon slamming the users hand or, if not the case, always in short range of the user.
Now try to summon a giant bat.
(Kuchiyose no Jutsu: Jaiantobatto) Summoning Technique: Giant Bat
Type: Supplementary
Rank: B
Range: Short
Chakra: 20
Damage: N/A
Description: The user will perform the summoning jutsu and summon a giant bat which is the same size of Sasuke's hawk. It is able to have two people on its back and fly with no problem and has wings capable of producing air waves strong enough to push back enemies within short range (C-Rank ability), which makes this it a difficult opponent. It can fly a high speeds and scratch or bite opponents. This bat has no elemental affinity but has an incredible hearing and the same sonar-like abilities as other Bats.
Note: Only summonable once per battle.
Note: The air waves count as one of the summoner's moves per turn.
