Now onto those hints:

Austin Powers - Austin Powers arch nemesis is Dr.Evil who is a parody of Blofeld.

Cher - Her name sounds like chair. Blofeld firstly appeared and was remembered as a mysterious man in a chair.

lock - a Lock is usually opened by a key. When saying those words back to back it sounds like Loki.

Blofeld vs Loki confirmed.
