Cortana, the artificial intelligent construct, from the ego-shooter video game Halo (developed by Bungie) as LoRA for SDXL 1.0.

The trigger word is "Cortana". You do not need to but you can also add "Hologram", "AI", and "Halo" to further enhance certain aspects of this character.

Optionally you can put "Body Armor" and "Human" into the negative prompt to suppress her wearing any armor as depicted in some art as well as the human form of her.

Strength of 1.0 works very well.

Cortana is a fictional character from the Halo video game series. She is an artificial intelligence (AI) that serves as the main AI aboard the UNSC Pillar of Autumn and helps Master Chief, the game's protagonist, in his mission to stop the Covenant from destroying humanity.

Cortana is also a virtual assistant developed by Microsoft that provides users with information and assistance through voice commands. It can be used to set reminders, send messages, make phone calls, control smart home devices, and more.

In future versions of this LoRA it is planed to control the variant of Cortana as characteristic to specific Halo game version with additional trigger words.
