Hmmm...Do Deidara's clay things count as summons? Because if not...
Chouji -> A butterfly or a boar
Danzou -> An eagle
Deidara -> Either a hawk or something that burrows like a mole.
Ebisu -> A goat... A fainting goat.
Gaara -> A tanuki
Hashirama -> A stag beetle or a horse
Hidan -> A bull
Hinata -> A peacock or a mouse. A white lab mouse, not an ugly rat.
Itachi -> A crow
Kakuzu -> A squid or an octopus
Killer Bee -> A hornet or a bull
Konan -> Swallows
Kurenai -> A moth or a lizard
Lee -> A cheetah
Madara -> An eagle
Neji -> A tiger
Roushi -> Lizards or salamanders
Shikamaru -> A deer or a bear
Shino -> A stag beetle
Tenten -> A spider
Tobirama -> A fish or a horse
Yugito -> A cat
Zabuza -> A lion
Zetsu -> I have to go with a Venus Flytrap or a Rafflesia
Its nice, fun thread to speculate.. for fun
Gaara - after losing Shukaku I would give him summon, either raccon/tanuki <just for the similarities with Shukaku, lol > or some kind of rat boss <raruto xD>
Chouji - butterfly
Hidan - tasmanian devil
Kakuzu - octopus.. but not Killer B
Hinata/Neji - swan
Konan - peacock
Kurenai - lizard sounds good
Lee - turtle, as Gai
Shikamaru - deer, hmm xd
Tenten - spider would be good for having too much "hands" xd
Zabuza - panther
Konohamaru - Enma monkey, hands down xD
Holy shit Konohamuru with Emna would be so awesome O_O
Another cool summon would be Mizukage with a lava eel.
Lol, can't believe I actually called Sasuke getting a hawk. Any speculation on where he picked up the summon? My guess is he got it from his family but never used it cause he didn't have the chakra for it till then. And only used snakes earlier because he was using Oro's chakra which was contracted to the snakes.
I think Sasuke getting a hawk was after he got rid of Orochimaru. I hope anime will show the explanation. From the other side, If big battle happens like for example vs Naruto And Naruto summons Gamabunta what will Sasuke summon in answer? Will it be a giant hawk?
