Looks really cool. Perhaps he can use the jetpack as a recovery move?
Unfortunately, the limitations of the game's custom character support would've prevented it from hapaning. also, the readme of the game says this of the game:
There's the X attack.
Usually very weak, yet quick. So it can be used rapidly with succession.
The Z attack.
A charged attack, quick uses will do weaker attacks, yet if you let it charge fully then release...
SMACK!!! Someone's getting a full-powered hit.
Also the over-Z attack.
This attack is executed by pressing the directions left or right while pressing Z at the same time.
It's very varied, depending on the fighter. It's very unique to the character.
EDIT: If you don't know by now, even though you looked at the above quote, then you should know that Super Smash Brothers NES only supports three attacks (to make it more "NES-like")
