Rush

Rush (ラッシュ) is Mega Man's faithful robotic dog, created by Dr. Light to assist Mega Man in his travels. He debuted in Mega Man 3. Initially, Rush was able to transform into a coil, a hoverboard, and a submarine. Since then, Rush appeared in most games related to the original Mega Man series, including crossovers like Marvel vs. Capcom and some cameo appearances like SNK vs. Capcom: Card Fighters' Clash, Super Gem Fighter: Mini Mix and Capcom World 2.

In Mega Man 6, he was upgraded and gained the ability to fuse with Mega Man to form the Power and Jet suits. In Mega Man 7, his jet and coil abilities returned, but he now had Rush Search, a detection mode. Also, both of his suit transformations were combined into one: the Super Adapter. In Mega Man 8, he has four new abilities, including a transformation into a motorcycle and healing abilities.

Rush Coil
Rush Coil (ラッシュコイル) is a coil platform that emerges from Rush's body and propels Mega Man to a higher level.

New Rush Coil
New Rush Coil (ニューラッシュコイル) is the modification of the Rush Coil from Mega Man 5. Rush's legs become the coil, and Rush is propelled with Mega Man. Mega Man must leap off Rush to reach his target.

Appearances:
 * Mega Man 5: No prerequisites.

Rush Jet
Rush Jet (ラッシュジェット) transforms Rush into a flying sled which Mega Man can ride. Its usage differs greatly from Mega Man 3 to Mega Man 4 and onward.

In Mega Man 3 and Mega Man II, Rush Jet will stay underneath Mega Man under any circumstances unless he 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 and Rush Jet will stay beneath him. 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 with using little or no energy.

In Mega Man 4 and later games, Rush Jet becomes more of a jet, his energy continually drains, and he will continuously move in the same direction (will make slight variations in vertical movement at the player's discretion), acting much more like 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.

When Rush appears in Mega Man 2: The Power Fighters, he will turn in Rush Jet and hit the boss when Mega Man uses a charged attack.

Super Adapter
The Super Adapter (スーパーアダプター) is a combination of the Rush Power Adapter and the Rush Jet Adapter. Its only appearance was in Mega Man 7, and is obtained by collecting the R, U, S, and H plates. They can be found in the stages of Cloud Man, Junk Man, Freeze Man, and Burst Man. The Mega Buster is replaced by a flying fist attack, similar to the Rush Power Adapter. The flying ability was reduced compared to the Rush Jet Adapter. Mega Man can't slide while equipped with this adapter.

There is an upgrade of the Super Adapter called Hyper Rocket Buster that can be bought in Auto's shop after obtaining his Hyper Bolt, or found in Turbo Man's stage, near a ladder where a Sniper Joe 01 is standing. Use Rush Search on the platform the Sniper Joe 01 was to find the upgrade, which makes the charged punch seek its foes.

Bass stole the plans of the Super Adapter from Dr. Light, and Wily created the Treble Boost based on this item.

Trivia

 * Rush's character concept is loosely based on Friender, a support unit of Neo-Human Casshern, a Tatsunoko Character since Friender has the same ability of transforming into various vehicles for Casshern. You can watch Friender here transforming into a jet, a drill-tank, and a submarine similar to Rush.
 * Rush on the Ruby Spears cartoon is patterned to Scooby-Doo since he is seen doing antics and enjoys eating "Scooby Snacks" before performing his tasks, given or pleaded by the characters to him.
