I just wanted to point out this, but the mid Demon isn't actually +15 It is indeed +4 like the frame data suggests. In matches a 6 frame low poke can beat out close to any options Scorpion has after this. B3, and B1 are both now 7 frames of start up due to being +4 which means they lose. Standing 1 and 2 are highs so they will also be stuffed.
Not every character will beat B3, or B1 but like I said 6 frame low pokes will do the job. Giving you only throw, or a down poke of your own as main options after this. Which is why I do not recommend it over ending combos in a teleport, despite the 1% of extra damage that it does.
