I just made a test run of Samus, 16 seconds, getting star finish, no item, hawk, speedster, no miss x8, no damage, full power, smashless, fighter stance, acid clear, with a final score of 1201151. I tested how many air drills it took to clear Samus, I did 3 down drill and did a back kick then cutter, and she came back down, so I tried 4 down drill, then back kick then cutter, and she died. So 4 is optimal.
I must admit, I was suprised at the power of a tool assisted drill attack. I think the final cutter can be improved to save one second, as it took a few tries and Samus was either dodging or using her VERY annoying up+b, so I just noodled around until I could kill her to see the score, so I can probably shave off one second with an optimal cutter.
This was SO much easier to do than Kirby/Yoshi Team, I did in in probably less than 10 minutes. and thegreginator, I'm sure it'll satisfy your action needs.
