I then created Twitter accounts for 3 of the main characters in the movie:

Motoko Kusanagi - an agent of Section 9, who is almost entirely cybernetic save her organic brain.

Batou - an agent of Section 9 and friend of Kusanagi. He is at least partially cybernetic.

Puppet Master - a sentient being formed from a government computer program being exposed to a massive stream of information/data 

Burner emails were used to set up the accounts, as well as screencaps from the movie itself and brief exerpts from the script.
