So on characters that can't recover from A Bowsercide, or if the stage will kill them anyway, here's a fun set-up that you can try which should beat neutral stand ups and ledge attacks. Basically, you'll want to short hop over the ledge, fast fall, then do a side b. If you do it correctly, then you should grab the opponent from low enough that the momentum on the way down will carry you low enough that you won't be able to land on the stage when Bowser rises back up into the air, which gives you a guaranteed Bowsercide regardless of percentile difference. This also works if you get a ledge trump and the opponent regrabs the ledge, just walk off to side b and they should automatically be too low to make it back. Hopefully the glitch will be fixed soon, making this technique a little more viable, but in the meantime, it should still work on certain characters and stages for now.
