Since Sonya was cut from the final release of Mortal Kombat Special Forces, many people aren't familiar with her look for that game. This LoRA was trained to generate that look. There is no activation word. Instead, use the character's physical description:
Example input: blonde hair, black pants, green cropped, white boots, black gloves, black headband, blue eyes, belt, white turtleneck, armband
I tested this LoRA with various checkpoints. It seems that checkpoints derived from AnyLoRA tend to produce better images. DPM++ 2M SDE Karras with 40 steps seems to generate good results. Use ADetailer to enhance her face.
