folks this is something that soon will be hitting front page,i finally figured out a way to correctly swap babalities,go to your char's mkscriptbinary(say in this case sektor),go to npc_sektor_baby,swap the name for instance npc_sindel_baby, and also swap it for the mko part(npc_sektor_baby.mko,turn it to npc_sindel_baby.mko) and voila! baby swapped!
though much like swapped fatalities,not all sounds will play unless the character who you borrowed the babality from is there.
tested this also on reptile,swapped his babality with kintaro's,works fine.
