works anywhere, and haven't had any issues with any of the characters so far. I try to hit the initial j. B on the way up as opposed to waiting for the peak of the jump. You still have room for an install combo after 236 B as well
Alternatively: You can end the combo with 5 B > 236 C for a true knockdown state.
Combo can likewise kill by switching Goku to Yamcha, using his assist around Recoome's beam attack, and ending with Lv.1 > Lv.1 > Lv.1+3. This would require about 4.5 bars to start.
