CCTV reveals Evie Amati stormed the garage armed with a fire axe and took a swing at bystander Ben Rimmer.
She has been jailed for four-and-a-half years – with her lawyer blaming the sex change operation.
Her legal team claimed the operation had left her in immense pain and fuelled her desire to kill strangers.
Amati left Ben with his face held together by four titanium plates that he will have for the rest of his life.
She was fuelled by drugs as she took the 2kg axe to the 7-Eleven in Enmore, Australia.
One hour earlier, she had posted on social media: “One day I am going to kill a lot of people.”
She was furious after she had a bad Tinder date with a woman in the hours previous.
