In true Simone Giertz form, Simone Giertz underwent brain surgery last Wednesday, and she's already cracking jokes.

The YouTuber and "Shitty Robots" creator, who announced she had a non-malignant brain tumor in April, shared her first post-op photo update on Monday, uploading a picture of her surgical scar to Twitter.

She captioned the image "super villain scar in the making."

Giertz has been vocal about her operation on social media, even in the face of a long and arduous recovery process. She even named her tumor Brian and sent it an eviction notice. On the day of her surgery, she said in a video that her surgeon had agreed to take images of her brain, and that she was excited to see them.

"I've always been convinced that I have a really beautiful brain," she said.

Later that day, a third party tweeted from Giertz's account to confirm that the surgery had gone well, visibly reassuring many of her fans. Then, on Saturday, Giertz tweeted another message -- a characteristically funny one -- in her own voice.

"I currently look like Smeagol right as he transitions to Gollum," she wrote.

To use a Giertz-coined phrase, that's some real #TumorHumor.
