Percival's first published work was in the monthly British comic Judge Dredd Megazine with a horror ‘strange cases’ tale written by Dave Stone. After several similar stories in the Megazine, he then went on to paint a nine part story set in Judge Dredd’s world in the Cursed Earth, with the series, Sleeze 'n' Ryder where Nick worked with acclaimed writer Garth Ennis.
The pair would later work together again for the British weekly comic 2000 AD on the Judge Dredd epic, "Goodnight Kiss" ... another tale set in the radioactive wasteland of the Cursed Earth, where Judge Dredd is hunted by the assassin, Jonni Kiss and the mutant Brotherhood of Marshalls.
Nick also painted the Sláine story, "King of Hearts" for 2000 AD where he worked with the co-creator of 2000 AD, Pat Mills.
Aside from his 2000 AD, work on various stories and painted covers, including a Dredd one-off story "Crime Prevention" with acclaimed comic book author, Mark Millar, Nick also produced work for Marvel Comics, MTV, Wizards of the Coast, Upper Deck Entertainment, Boom! Studios, Electronic Arts, Sony, Warner Bros., Activision, Atari, Sci Fi Channel, History Channel, Microsoft and Fantasy Flight Games.
He also became prolific in the video game and animation industries where he ran an animation studio in the UK. He directed computer generated cut-scenes for video game such as Alien Escape, Steel Soldiers, Carmageddon TDR 2000 and the Games Workshop licensed video game of Gorkamorka. His company also developed their own computer generated short films and Nick presented one of these successfully at the Cartoon Movie Festival 2002 in Berlin.
Nick is the author and illustrator of The Enchanted ... an original graphic novel, to be adapted into a feature film by Ron Howard's Imagine Entertainment.
