1. being how Vampires are fairly cowerdly in nature and wont fight unless they are fairly certain they will win mainly being since when a vampire dies after his or her span of hundreds of years, they know exactly were their going, Hell; and they know thier punishment will most likely be worse than the general population of Hell.
2. Bella is a fine fighter against men and women, however his streagnth lies in his terrorfying presance which is enough to cripple his prey, Chucky would not feel terror since he is in all a ctuality a reincarnated serriel killer from hell who through demonic possesion occupies a child's doll.
3. Chucky is able to stalk in both day and night, making a sleeping Lugosi an easy target for Chucky.
4. the main advantage Bella would have over Chucky is his comand of magic and ability to predict actions of his prey. Bella is also more cunning and thought out, unlike Chucky who acts more on his emoutions and dosnt really have much skills other than the fact that its very difficult to kill him.
Conclusion.
Due to the above i belive the fight would be very close and intresting, one day I hope to write a book about cotton picking in which i make many cleaver allusions about this fight that would make your grandmother cringe at the sight of such verbose dipictions of gore. any way, Bella Lugosi is an amazing actor and by far offers the gretist dipiction of Dracula, but Chucky has far more advantages and would most likly win, but hey Prove me wroung.
