When Naruto is about to finish off Pain with the Rasengan, Naruto and dead Jiraiya's Rasengan bears a strong resemblance to dead Goku and Gohan's Father-Son Kamehameha from Dragon Ball.

Naruto also does the same thing in Naruto Shippuden: Ultimate Ninja Storm 3 when he's wearing Goku's costume and performs his "Ultimate Jutsu Finish Chance".
