I'd rather not. Besides, in a prior post, it was stated that the Ghostbusters' equipment would be effective against a terminator and Jason. So, it's apparently not just ghosts that can be neutralized by the Ghostbusters.
Hellboy isn't even a normal demon,he will simply shoot the ghost busters before they can even turn on their weapons.
Also even if it materred, no prep(read OP),so they can't go and researcH how to banish him(I don't know if that's even possible given his importamce and heritage)
@Kellar21: The Ghostbusters aren't necessarily going to all stand in one place. I wonder, though, what effect the proton packs would have on Hellboy. Does anyone have an opinion about the other battle?
I suppose Chucky would win...But, it would be a weird fight. Chucky wobbling around and chasing a panicky C3PO. Eventually 3PO falls over and is stabbed repeatedly to no effect, but all the while 3PO is screaming in surrender...making Chucky the victor.
...OR...Chucky and C3PO find a kindred spirit in one-another (senitience embodied in something inorganic), become friends and Chucky joins the Star Wars Universe...
