Super Adapter

Super Adapter is 's Final Smash in Super Smash Flash 2. Mega Man summons Rush, his robotic dog, to combine with him thus creating Super Mega Man, known in Japan as Super Rockman. While fused, Mega Man gains the ability to jet upwards if the jump button is held, slow descent, and rocket fist projectiles, which deals 15% to the opponents. In terms of Final Forms, Super Mega Man is a special case, as he only has one attack, but he's controlled exactly as one would control a regular character. Despite he works, and was coded in the same way as a Final Form, he's been officially labeled by the Smash Flash DOJO!! as a "Semi-Final Form".

Origin
The Super Adapter is an upgrade to Mega Man's armor appearing exclusively in Mega Man 7 which, much like in SSF2, is used by combining with Rush. It is obtained by collecting the R, U, S, and H plates that can be found in the stages of the first 4 robot masters: Cloud Man, Junk Man, Freeze Man, and Burst Man.

In function, the Super Adapter is a combination of the Rush Power Adapter and the Rush Jet Adapter from Mega Man 6. While equipped, the Mega Buster is replaced by a flying fist attack similar to Hard Knuckle from Mega Man 3. Unlike in SSF2, he cannot fly like he can with the Rush Jet Adapter, instead being able to double-jump using the rocket plates on the suit. Mega Man also can't slide while equipped with this Adapter because it's too bulky.

Trivia

 * On the Smash Flash DOJO!!, this move was called "Super Adaptor", despite being officially known as "Super Adapter" in Mega Man 7. This however, could be some sort of homage to Mega Man 4, where it was labeled as "adaptor", rather than "adapter."
