Katekyo Hitman Reborn!
Thunder Strike from Twenty Years Later (2x10)
:
Lambo's fight versus Leviathan of Varia. As a 5 year old and a 15 year old, he stands no chance to the "Levi Volta" attack of Levi. However, when the 15 year old Lambo used the 10 year bazooka, Lambo from 20 years later appears. The 25 year old defeats Leviathan with relative ease using his "Electricco reverse" and "Electrico Cornuta" techniques, but the 5-minute limit of the 10 Year Bazooka ended, and Lambo reverted to his 5 year old form.
