although it is true that cloud and leon havent faught for very many battles side by side and learned each others moves and tehy dont do alot of cooperation techniques, they still have raw power and speed and agility. although riku and sora have teamwork on their side, i dont think it will sway the battle too much because if cloud was to be double teamed by riku and sora, then im pretty sure that leon would wait for the oppertune(sp?) moment and lunge at one of them with much force, catching them off gaurd, which would force sora or maybe riku to look back at their partner which would also give cloud time to regroup and jump in for a feirce attack, OMNI SLASH!!!!!!!!lol XP
