Rush Jet

Rush Jet (ラッシュジェット) is a recurring item in the original Mega Man series. When used, Rush appears and transforms into a flying sled which Mega Man can ride, his rear legs becoming jet thrusters.

As an item
In Mega Man 3 and Mega Man II, Rush Jet will stay underneath Mega Man under any circumstances, unless Rush hits a wall. He acts as more of a personal hover device instead of a jet, allowing Mega Man to move in any direction, or stand still entirely, following the player's input. Also, Rush Jet's energy will only deplete if Mega Man is currently standing on him. Because of this, if a player continuously jumps, large pits can be crossed while using little or no energy. Due to its behavior, Rush Jet can be used to safely defeat Wily Machine 3.

In Mega Man 4 and later games, Rush Jet became more like a jet. When Mega Man jumps on him, Rush will only move forward and his energy will be continually drained, and he will continuously move in the same direction, making slight variations in vertical movement at the player's discretion, acting similar to Item-2 from Mega Man 2. This change was made because once Rush Jet was acquired in Mega Man 3, it could be used to bypass situations where Rush Coil or Rush Marine were required and did so more effectively and easily than they could.

In Mega Man 7, Rush will teleport out if he is hit, so extra care is required when using Rush Jet as he may drop Mega Man.

Other appearances
In Mega Man 8, Rush Jet is used to pass a section from two stages. The first one is in Tengu Man's stage, and the second in Wily Stage 2. During these segments, Rush Jet behaves similarly to how it acted in Mega Man 3, but is constantly moving forward and lasts until the end of the section, making the gameplay of the section akin to a shoot 'em up. These sections also featured giant Party Balls which contain one of four power ups for Mega Man, summoning Beat, Eddie, or Auto to assist him, or equipping a cannon on Rush.

In Mega Man 2: The Power Fighters, while accompanying Mega Man, Rush will turn into Rush Jet and fly to hit the boss when Mega Man uses a Charge Shot or a Mega Upper.

Rush Jet also appeared in scenes from Mega Man: The Power Battle and Super Adventure Rockman.
