Not sure if this has been mentioned before, but this combo seems to work on all weight classes:

This works on all weight classes and guarantees you a pick up straight away. The timing on heavies is really tight. You have to be perfect with the timing and you'd probably be pretty screwed if it's on a laggy monitor. On light and meds though, it's easy to time and hard to miss.
I'd say this is a great alternative to



unless you want to go for grab mix-ups. This deals a decent 75 damage if you land it and you'll get your guaranteed pick-up.
For


to connects on heavy characters after launch, the opponent needs to be launched at the last few active frames of



, so the further you are, the better it'll be. If you're too close, then you'll be stuck in recovery/active frames and miss your


.



has 3 active frames, meaning that if you launch at max range, you'll have less time to recover. I'd say the sweet spot for this is around range 3. Since Bayman has a smaller hit-box, you'll have to be much more precise. Seriously, this combo is a bitch to do on Bayman. You have to be pixel-perfect in your positioning.
If you're looking for more damage and if you have a wall beside you, then got for the grab after launch, though on open ground, the grab only deals an extra 2 damage (77) and the opponent is thrown far away.
