Just a Zero to Death combo I learned from Luigi recently and decided to try.
I saw the combo while watching Smash players, more precisely on the VGBootCamp channel that posts a lot of video of competitive game.
I don't know if it works on light and smaller characters (because of the hurtbox difference between them) but I know it works on heavy characters like DK, K.Rool, Bowser, DeDeDe and etc...
Combo:
(ZTD-String) Grab ~ D-Throw, D-Tilt 4x (two on each jump always with fast fall) *run into opponent*, S-Tilt 2x, Grab ~ D-Throw, RAR Up-Air 3x and finish with B-Air.
Make sure you use the second jump during the 2nd hit of the Up-Air and stay on your back while in the air to ensure it hits the B-Air.
