If anyone is interested here are a couple combo areas that haven't been discussed.
1) 236 S > max fire > red RC > dash > c.S > j.S > j.P > J.S > jc > j.S > j.P > J.S > j.Hs > j>D (112 dmg) (can be done full screen)
With more testing and different weights from different characters the timing is way tighter depending on who your doing it on.
2)236 S > max Fire > reload > quick fire (50 dmg)
2) 236 P> 2P (has to hit on first bounce)> red RC > dash > 2P > 2k > c.S > HS > 236 K > berry explodes > c.S > J.S > j.P > J.S > jc > j.S > j.P > J.S > j.Hs > j>D(106 dmg)
i'm not the best combo maker out there so im sure these aren't optimized, but they are potential new areas. For instance, I often IAD backwards why loading a berry grenade. Then toss it out in some fashion before I land or right as I land. If you were to the land a rifle shot post grenade toss, then roman, the combo could deal way more damage because of the extra air time and damage from the berry explosion
