Cooperation ninjutsu are little-explored in the series. Although there are numerous of examples of characters working together and/or jutsu being performed in combination, Kiba Inuzuka's partnership with Akamaru being a prime example, these are never labelled "cooperation ninjutsu" and do not seem to exactly fit the definition. The few explicit examples are typically combinations of nature transformations, where one nature is used to make another nature even stronger, such as the Scorch Release: Halo Hurricane Jet Black Arrow Style Zero, a combination of fire and wind.
