This article is about the "Heretic" Banshee introduced in Halo 2: Anniversary multiplayer. For other Banshee variants, see here.
The Type-26BZ is a specialised "ordained" Banshee built upon the frame of the standard Type-26B Banshee. Like its Type-26AZ counterpart, it features brown-orange panelling and exposed mechanisms, alongside a series of glowing lights not present on the regular Type-26B. The Type-26BZ is otherwise seemingly near-identical in function to standard Type-26B Banshees.
The Type-26BZ Banshee is the "heretic" Banshee featured in the multiplayer component of Halo 2: Anniversary - the heretic Banshee seen in the game's campaign mode is the Type-26AZ Banshee. The vehicle behaves identically in-game to the standard Banshee. The design was not given a formal designation difference until a 2015 Halo Waypoint universe entry.
