Super Adapter

Super Adapter is Mega Man's Final Smash in Super Smash Flash 2. Mega Man summons Rush, his robotic dog, to combine with him thus creating Super Mega Man. While fused, Mega Man gains the ability to jet upwards if the jump button is held, slow descent, and rocket fist projectiles. In terms of Final Forms, Super Mega Man is a special case, as he only has one attack, but he controls 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.

Trivia

 * On the Smash Flash DOJO!!, this move is called "Super Adaptor", depite 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 written as "adaptor" rather than "adapter".
