The Delta Mega (デルタメガ) is the support and carrier mecha from Denji Sentai Megaranger, known as the Delta Megazord in Power Rangers In Space. As the team's second major mecha, it backs up the Galaxy Mega (Astro Megazord) and is called into battle as reinforcement. It is defined by two modes: a sleek shuttle/spacecraft form for its approach, and a powerful robot mode in which it can fight on its own.

In robot mode, the Delta Mega mounts the hefty Gatling Blasters on both arms and lays down massive suppressing fire. Its real party trick, though, is the combination: the Delta Mega splits open and wraps around the Galaxy Mega as armor, forming the mighty Super Galaxy Mega (the Astro Delta Megazord in In Space). The Gatling Blasters relocate to the shoulders and deliver triple the firepower, while the finishing move is the Super Galaxy Knuckle, a classic rocket punch that tears straight through the enemy. Episode 31 adds a further finisher, the Big Bang Attack.

As a DX toy, the Delta Mega launched by Bandai in the late 1990s — in Japan as the "DX Delta Mega," and in the US as the "Deluxe Delta Megazord" from Bandai America. Both transform from shuttle to robot and dock onto the separately sold Galaxy Mega / Astro Megazord to combine into the Super Galaxy Mega / Astro Delta Megazord. As was typical for the era, the Japanese DX line was regarded as the more premium build, while the US releases were a touch simpler; smaller 5-inch Action Zord versions were also offered at a friendlier price point.

Collectors who prefer modern reissues are covered too: Bandai later revived the pair as Super Mini-Pla (Denji Gattai Galaxy Mega & Gattai Delta Mega) — a detailed model-kit set that preserves every transformation and the full combination into Super Galaxy Mega. A must-have for any Megaranger / In Space display shelf.
