Jenda is an entertainer and diva who has made numerous appearances around Whanganui at functions, events, art gallery shows and comedy nights over the past two years.
She was "discovered" by Mr Graves in 2014 when he was studying art at Whanganui UCOL, but has been retired for the past six months.
"Jenda was a performance artwork that went a little bit too far - that's how I'd describe her," Mr Graves said.
"I was in my third year and I'd been working on impersonating other performers and looking at how they had created personas for themselves. Then, in the middle of the year, I felt like I needed to go a bit further, so I decided to create my own alter ego, who is an original but also based on other archetypes."
Jenda first appeared in a series of live performances at Whanganui UCOL.
Mr Graves said the experience of being Jenda was a fascinating one.
"She is my personality but much, much bigger. And she has some interesting habits that I don't have - for instance, she's very untidy, whereas I'm not.
"She can be quite out of control. Some of the things that come out of Jenda's mouth really surprise me."
Tonight's show is likely to be Jenda's last in Whanganui for some time, as Mr Graves is going overseas for an extended period in August.
He said Jenda may well travel overseas as well.
"I think she'd like to take on the world."
