Superman, Cruella de Vil and Wonder Woman are not usually top of the guest list for a family party.
But one couple decided to invite more than 100 of the world's most famous super heroes and villains to watch them renew their wedding vows.
Iron Man, Dick Dastardly and Catwoman also joined Neil and Shirley Armstrong as they celebrated 20 years as husband and wife.
The Lincoln pair walked down the aisle dressed as arch enemies Batman and Poison Ivy.
And accompanied by the famed theme tune, they were greeted by family and friends in full costume.
Former army lance corporal Mr Armstrong, of Waddingworth Grove, said: "We always said we wanted to renew our vows when we got to 20 years and with us both turning 40 it made it an even better time to do it.
"We thought we'd do a fancy dress theme and we both like super heroes.
"Because we had already done the formal ceremony we thought it would be a fun thing to do. We've been together since we were 17 years old and so it was a great chance for us to show our commitment to each other.
"She's my best friend, but we probably don't say 'I love you' enough."
The event was held at Lincoln County Hospital Sports and Social Club, in St Anne's Road, on Saturday, September 22.
An emotional ceremony saw the couple exchange rings and make personal vows.
Mrs Armstrong said: "When you say things like that it brings it all out and you can't keep it in.
"A lot of people here today were there the day we got married and I think a lot of them didn't think we would make it, so I was so pleased they could be here to celebrate it with us."
The couple got married in Lincoln on September 5, 1992.
Mr Armstrong's brother Carl, 35, who was dressed as Batman's sidekick Robin, was the best man at both ceremonies.
He was joined in an opening procession by the rest of the couple's family, including their three children.
Alex, 17, was dressed as cartoon heroine She-Ra and her twin 14-year-old sisters Megan and Beth went as The Joker and Sub-Zero from the video game Mortal Kombat.
Registrar Glyn Evans said the super hero idea theme was unusual for civil ceremonies.
"I've done themed ceremonies before, like James Bond or medieval, but never a super hero one," he said.
Mr Armstrong is a project engineer at Hindles of Lincoln and his wife is a dinner lady and cleaner at Lincoln Castle Academy.
This year, the Armstrongs bought their own home through the Government's Right to Buy scheme, after renting it for eight years.
Ten years ago the Echo highlighted the family's two-year struggle to secure a council property following Mr Armstrong's decision to leave the Army.
But a home was eventually found for the family.
