The Landick Brothers (Japanese: ランディックブラザーズ) are a trio of auxiliary mecha — known as Gosei Headders — from Tensou Sentai Goseiger (2009–2010). They belong to the Landick Tribe, the land/earth tribe of the Gosei Angels represented in the show by Gosei Black (Agri) and Gosei Yellow (Moune). In the US adaptation Power Rangers Megaforce (2013) the set is called the "Land Brothers Zords." It comprises three Headders: the Kuwaga Headder (stag beetle), the Sai Headder (rhinoceros) and the Tyranno Headder (Tyrannosaurus), renamed Beetle Zord, Rhino Zord and Dino Zord respectively for Megaforce. Rather than a standalone flagship Megazord, this is a support set that expands the main robot, Gosei Great.

The three Headders dock onto an already-assembled Gosei Great to form Landick Gosei Great (Megaforce: "Land Megazord"), a samurai-styled configuration built around speed and kicking power. The Kuwaga/Beetle Headder becomes the head, the Tyranno/Dino Headder the left foot and the Sai/Rhino Headder the right foot. Signature moves include the Landick Brothers Attack and, in Megaforce, the Beetle Headbutt and Dino Kick, plus the finisher Victory Charge – Land Strike, in which the rhino Headder's horn works like a drill for a downward drill-kick. As with all Gosei Headders, the three were summoned in the series via Gosei Cards.

As a toy, the set was released in 2010 by Bandai Japan within the Goseiger "Gosei Header Series" as the DX Landick Brothers; Bandai America issued the equivalent Land Brothers Zords for Megaforce in 2013. The three small Headders are made essentially of plastic (PVC/ABS) and, unlike some of the larger DX flagship robots, carry no significant die-cast. Their play value lies less in individual transformation than in the plug-in combination gimmick: they replace the standard head and foot Headders of the separately sold DX Gosei Great and can be freely swapped with its parts. Owning DX Gosei Great is therefore a prerequisite for displaying the complete Landick Gosei Great formation.
