Fire Release: Great Flame Rasengan

Jiraiya's variation of the Rasengan added with his fire nature. Jiraiya creates a normal Rasengan and covers it in flaming fire chakra. He then hits the opponent, causing a blazing maelstrom of fire, reducing the victim to ashes.

Trivia

 * This technique is a contradiction of the Rasengan being unable to have an elemental chakra being mixed into the technique prior to Naruto's Wind Release: Rasengan, an attribute the Fourth Hokage intended to create but lacked the time to do so.
