He's voiced by Satoshi Tsuruoka and dubbed by Robert O'Gorman in English.
Role
Crump was an only child and his parents had no time for him, so he spent his time counting things. When he found a book about how penguins cared for their young, he became obsessed with penguins. He soon became an accountant and member of the Big Five at Kaiba Corp. Once Kaiba took over, Crump wanted an all-penguin theme park, but Kaiba refused, destroying his dream of a career combining numbers and penguins.
The Big Five teamed up with Pegasus J. Crawford to take over Kaiba Corp (much like how they teamed up with Kaiba to overthrow Gozaburo Kaiba), but Pegasus was defeated by Yugi and Kaiba fired them. They trapped Kaiba in the virtual world, but were trapped in the virtual world when the Five Headed Dragon was destroyed. After a while, their bodies were destroyed.
Otaki as Penguin Nightmare
Eventually, they entered Taylor's body (which was stolen by Nesbitt) and dueled Yugi and Joey at once. Crump dueled for two turns before Johnson took over, refusing to let him take over at first. After they were defeated, Noah gave them no more chances and deleted them.
Noah imprisons the Big Five.
Personality
Crump is obsessed with penguins. He is also played for comic relief sometimes though ironically he has the most tragic backstory. Despite this, Crump is quite sadistic, as he intends to leave Tea frozen forever in the virtual world, where the other four merely intended to imprison their victims without being frozen (though it is implied they would suffer through such imprisonment anyway). Crump Is also perverted as he creeps out Tea and is hugely admiring of himself in front of her.
Yu-Gi-Oh! The Abridged Series
In LittleKuriboh's parody Yu-Gi-Oh! The Abridged Series, the Big Five are called Team 4Kids due to working for 4Kids which, in the Abridged Series, is an evil organization who censor the show, cancel it, and try to kill Yugi and Kaiba. Like the other members of the Big Five and Noah, Crump has a different voice actor than LittleKuriboh. Like in the anime, he is obsessed with penguins; The Abridged Series takes this a bit further, as he randomly says "Penguins!" In Episode 49, Crump dueled Téa; unlike in the anime, however, Crump won and took control of her body.
For a while, Crump was able to pretend to be Téa, although Yugi was suspicious that she was acting weird. In Episode 53, he was kicked out by Marik, who had moved to Téa's body after Bakura was defeated by Melvin, and later took part in chasing after Joey, Tristan, Serenity, and Duke. After all the Big Five were defeated by Yugi and Joey, Noah banished them to the darkest corners of the internet. Crump was sent to 4Chan, repeating the word "penguins" in his Nightmare Penguin form.
