Here is an updated version of the previous combo. I did some more testing and it seems like this does the best damage.
I can't find anything else that does more damage for 1 bar, mid-screen, and that starts with a 22-low scoop. This does 41 % damage, and that's not even including a jump-in
41 %, mid-screen, 1 bar of meter, and trait is activated mid-combo:
22-low scoop, 11-trait, f2-frostbreath, b3, j3, 3, flying punch
Updated timing notes for easier execution:
After low scoop, you need to hit 11 at just tge right time. The best way to do this is think of the spinning enemy after low scoop as a clock. Hit 11 when the enemy's head is at 8:00.
To properly make sure you hit f2 after trait as soon as you are allowed to, use the rumble in your controller as guide. When Supes uses trait, the rumble the controller does indicates the point where it can then be cancelled.
Also, it is much easier to finish the combo with a j2, 3, flying punch instead of a j3, 3, flying punch. You do 39 percent instead of 41 percent, but much less chance to drop, and it is still the most damage you can get off a 22-low scoop

You can do 1-trait instead of 11-trait if you are more comfortable with the timing, and it will NOT lower the damage. You still get the full 41%. Doing 1-trait reduces the risk of whiffing the second 1, however since the second 1 lifts the enemy in the air a bit more, you may have to be sliiiightly faster on the f2 that comes after trait. Lastly, doing 1-trait instead of 11-trait also has puts slightly less gravity in the combo, making the j3, 3, flying punch at the end easier to connect.
