hmm! this is creative and I like it a lot, but I'm iffy on the attacks. in particular, the tornado blast has an odd input, and I'm not sure if having a Robobot Mode discard itself is a good idea. I'd give it an "OK".
Tornado Blast would likely destroy enemies you want to scan. Due to the homing effect, it would destroy mid-bosses it is used against before they can be scanned as well. I would have made it "Hold A, X" so that it wouldn't kill foes unless you were trying to kill them.
It's okay. I'm a terrible artist too. Also, I don't downvote things based on artwork. I will say that the Tornado Jump is a really good speed increasing move, as you an jump over enemies to kill them instead of jumping on top of them and is unique as well.
Hm, Hantho makes a valid point about mapping an attack to the X button. The only ability that does that is Hammer, and it requires a specific input to do so. I still think it's a novel idea, though - I'd like to see more copy abilities with desperation attacks like that.
I especially like that you mapped an attack to the jump button - have any abilities done that prior? I know Wing, Jet, and their ilk have unique multi-jumps, but I don't think any abilities have turned the standard jump into an attack before. Very neat idea.
That attack would be multi-hit, deal more damage as a result and last for a shorter time, but I thought all that up after posting it. I couldn't really think of any good dash attacks either, and I wanted a dash attack.
