DC Multiverse headswaps, does the whole line have the ability to remove heads naturally?
 

Hi all, curious as to if anyone knows when it comes to Mattel's DC Multiverse line if even the figures that come without alternate heads are able to have their heads removed just as easily as the figures with alternate heads?

Also, do those in the Multiverse Signature Collection side of the line (i.e. Lynda Carter/Wonder Woman, Val Kilmer/Batman, etc.) have the ability to remove their heads naturally too?

Thanks for any help :)
