Banjo & Kazooie's Final Smash
Banjo & Kazooie's Final Smash does not currently have a known name.
In this Final Smash, anyone hit will be sent into a cutscene in which Banjo & Kazooie summon the Jinjonator, who rams into any trapped opponents multiple times, before charging forward for one final hit with four Jinjos following.
In the original Banjo-Kazooie, the Jinjonator makes its first and only appearance in the final boss battle against Gruntilda. In the penultimate phase of the fight, she casts a shield that grants her immunity to all of Banjo and Kazooie's attacks. Four Jinjo statues then rise from the ground, and activating them summons four Jinjos, who attack Gruntilda and knock her off her broom; after this, a single, large Jinjo statue rises, dubbing itself "the mighty Jinjonator". After activating the statue, the four previously summoned Jinjos are absorbed by the Jinjonator, who rams into Gruntilda multiple times, knocking her off of her tower with one final blow.
