A number of posts on this blog have covered how characters from the Harry Potter books/movies not currently available as minifigures can be custom-made from existing available parts.
These figures are:
- Colin Creevey
- Gilderoy Lockhart
- Percy Weasley
- Bill Weasley
- Rita Skeeter (follow up post covering her animagus form)
- Sirius Black (Order of Phoenix appearance)
- Vernon Dursley
