Wonderwing

The Wonderwing is an ability learned from Bottles in Clanker's Cavern in Banjo-Kazooie and can be executed by holding and pressing. While Wonderwing is active, Kazooie will shield Banjo with her wings, making the pair invulnerable to harm at the expense of one Golden Feather every two seconds. Most enemies will die instantly when touched by the Wonderwing shield, making it effective in quickly dispatching stronger foes like Snacker and making it the only move capable of killing undead enemies and bees. This ability can also be used to cross dangerous terrain such as superheated sand or bramble, as well as absorbing damage from long falls.

In Banjo-Tooie, most enemies will flee at the sight of the Wonderwing, sometimes forcing the player to chase them down just to hit them. The Wonderwing will protect Banjo and Kazooie from being crushed by various hazards, but only when together, since neither of them can use the ability on their own (there's no explanation as to why Kazooie can't use it on her own). The move is only required once in Banjo-Tooie: the super heated waterfall in Hailfire Peaks. The overall combination of less intended uses, the increased difficulty of using it to attack, the fact that enemies respawn quickly anyway, being unable to use the move while split up, and its uselessness in toxic gas and boss fights makes the move far less useful.

In Banjo-Kazooie: Grunty's Revenge, the Wonderwing can only be activated by pressing while standing on a Wonderwing Pad.

In Super Smash Bros. Ultimate, the Wonderwing appears as the duo's side special attack. It is now performed as a barge and cancels out most other attacks used against it. However, it may only be used up to five times per life, represented by Golden Father icons over the duo's heads when they use it. If they try to use it again, they will simply trip. It is unable to damage shields, and in fact causes them to soar past shielded characters, potentially allowing them to hit the duo from the back. The move also does not protect from grabs.
