Fanged metal teeth, skin implants, a split tongue, and eccentric tattoos are just some of the unique changes Marcelo "B-Boy" De Souza Ribeiro has made to his body over the years.
As such, he has been dubbed the "most modified man in the world" and has spent an estimated £29,000 on his quest to look like an "alien devil" - but he's not finished transforming his body just yet.
The 40-year-old dad, who believes 98 percent of his body has been altered, has recently had his hands tweaked, removing his index finger and splitting his hand in half.
Now, in a "world first" modification he plans to remove excess muscle and skin to define his appearance.
Marcelo, a tattoo artist from São Paulo, Brazil, said: "I've made a new modification that doesn't exist in the world yet.
"I had researched body modifications in the world and from what I saw, no one has yet made a similar one.
"I drew inspiration from movies and documentaries I watched about UFOs.
"The appearance I was looking for in my hands was that of an extraterrestrial."
As well as all his modifications, the parent has 1,500 tattoos and claims his latest changes have taken four months to complete and cost £655 in total.
He started in February, when he had excess oil and fat removed from the sides of his left hand in a bid to make it slimmer.
Explaining the process, he said: "I began to see the possibility of making an opening in it through the middle where you can have [a permanent] split.
"After how I made [this hand], I found it interesting to do the other one in a different format.
"The procedure was studied two weeks before surgery and we removed the index finger [at the knuckle].
"Now, I've had muscle and skin removed with a surgical scalpel to make the hands as normal as possible to look the way I intended to have it.
"I wanted to finish mine perfectly so that it looks natural as if I was born with the format."
Marcelo claims each process was quick and smooth, with him scoring the pain only a six out of ten.
Now, that he's fully healed and is used to his new "claw" he says he has no regrets about the changes he's made to his body and thinks people are loving his new look.
He added: "At first, people were surprised with how the hand looked.
"Today, they always ask me about the hands and to take pictures.
"Amazingly, I don’t have any difficulties with handling any activity I do with my hands.
"I can type, pick up and play musical instruments – it's all normal.
"I have no regrets about the procedures.
"I'm happy and satisfied."
