'''Bowser Jr.'s Robot Reactor''' is [[Bowser Jr.]]'s first [[galaxy]] in the game ''[[Super Mario Galaxy]]''. In it, [[Mario]] fights [[Megaleg]] to earn a [[Grand Star]].

===Starting Planet===
[[File:SMG Robot Reactor Starting Planet.png|200px|thumb|left|The Starting Planet]] 
This is a very small planet. Mario is required to entice a [[Bullet Bill]] to follow him and break open a cage to reveal a [[Launch Star]], and then use that Launch Star to reach the Robot Reactor. This metal planet has a [[black hole]] that Mario needs to avoid. There are also other cages that can be broken to reveal [[coin]]s or a [[1-Up Mushroom]]. It is also infested with several [[Goombeetle]]s, which make it slightly harder to traverse the narrow pathways while being pursued by a Bullet Bill. There is an odd shortcut on this planet. If the player [[Triple Jump]]s off the cage with the [[Launch Star]] and [[Spin]] they can reach [[Megaleg]] faster.

===Robot Reactor===

This is where [[Megaleg]] is found and battled. It is fairly small and orange-brown, with many technologic symbols all over it. It has small rectangular areas on it that are transparent and seem to have computer components inside them. Despite Megaleg's probable immense weight, the transparent panels never break if Megaleg stomps on them; all that happens is a cloud of dust rises up. In the underside, there are several glass containers around the back of the planet that can be destroyed with the help of Bullet Bills for items. If players go to Megaleg's back leg, they find a 1-Up Mushroom. The Robot Reactor orbits the starting planet.
