Question:
The Joker is a fictional supervillain created by Bill Finger, Bob Kane, and Jerry Robinson who first appeared in the debut issue of the comic book Batman (April 25, 1940), published by DC Comics. Credit for the Joker's creation is disputed; Kane and Robinson claimed responsibility for the Joker's design, while acknowledging Finger's writing contribution. Although the Joker was planned to be killed off during his initial appearance, he was spared by editorial intervention, allowing the character to endure as the archenemy of the superhero Batman. In his comic book appearances, the Joker is portrayed as a criminal mastermind.
The Joker debuted in Batman #1 (Spring 1940) as the eponymous character's first villain, shortly after Batman's debut in Detective Comics #27 (May 1939). The Joker initially appeared as a remorseless serial killer, modeled after a joker playing card with a mirthless grin, who killed his victims with "Joker venom": a toxin which left their faces smiling grotesquely. The character was intended to be killed in his second appearance in Batman #1, after being stabbed in the heart. Finger wanted the Joker to die because of his concern that recurring villains would make Batman appear inept, but was overruled by then-editor Whitney Ellsworth; a hastily drawn panel, indicating that the Joker was still alive, was added to the comic. The Joker went on to appear in nine of Batman's first twelve issues.  The character's regular appearances quickly defined him as the archenemy of the dynamic duo, Batman and Robin; he killed dozens of people, and even derailed a train. By issue #13, Kane's work on the syndicated Batman newspaper strip left him little time for the comic book; artist Dick Sprang assumed his duties, and editor Jack Schiff collaborated with Finger on stories. Around the same time, DC Comics found it easier to market its stories to children without the more mature pulp elements that had originated many superhero comics. During this period, the first changes in the Joker began to appear, portraying him more as a prankster than threat; when he kidnaps Robin, Batman pays the ransom by check, meaning that the Joker cannot cash it without being arrested. Comic book writer Mark Waid suggests that the 1942 story "The Joker Walks the Last Mile" was the beginning point for the character's transformation into a more goofy incarnation, a period that Grant Morrison considered lasted the following thirty years.  The 1942 cover of Detective Comics #69, known as "Double Guns" (with the Joker emerging from a genie lamp, aiming two guns at Batman and Robin), is considered one of the greatest superhero comic covers of the Golden Age and is the only image of the character using traditional guns. Robinson said that other contemporary villains used guns, and the creative team wanted the Joker--as Batman's adversary--to be more resourceful.

Question:
Skinny Puppy is a Canadian industrial music group formed in Vancouver, British Columbia in 1982. The group is widely considered to be one of the founders of the electro-industrial genre. Initially envisioned as an experimental side project by cEvin Key (Kevin Crompton) while he was in the new wave band Images in Vogue, Skinny Puppy evolved into a full-time project with the addition of vocalist Nivek Ogre (Kevin Ogilvie). Over the course of a dozen studio albums and many live tours, Key and Ogre have been the only constant members.
Inspired by the music of Suicide, Cabaret Voltaire, Chrome, Throbbing Gristle, Nocturnal Emissions, Portion Control, and The Legendary Pink Dots, music which had been accessible to the band primarily via tape exchange, Skinny Puppy experimented with analog and digital recording techniques, composing multi-layered music with synthesizers, drum machines, acoustic percussion, tape-splices, found sounds, distortion, samplers, and conventional rock music instruments. They also incorporated samples from films and radio broadcasts into their songs, and applied liberal amounts of distortion and other effects to Ogre's vocals, which are often delivered in a stream of consciousness style. Lyrics commonly reference social and political topics including animal rights, environmental degradation, drug addiction, suicide, war, and the right to privacy. They have also highlighted events such as the Tiananmen Square protests of 1989 and the AIDS epidemic. These themes were often lyrically and conceptually intertwined. Skinny Puppy's often informal, improvisational approach to musical composition is indicated by use of the term brap, coined by them and defined as a verb meaning "to get together, hook up electronic instruments, get high, and record".  Skinny Puppy's musical style has encompassed a wide selection of different genres, ranging from ambient music and synthpop, to noise rock and industrial metal.; the group is generally considered to be a pioneer of the electro-industrial genre. The Village Voice described Skinny Puppy's early work as "dark electro-pop", while Bill Coleman of Billboard magazine described Skinny Puppy as a "moody techno-outfit", going on to report their delivery as "aggravating". People magazine called Ogre's lyrical delivery as "incomprehensible", and likened the group's use of sampling to noises heard on "a TV set in an adjoining hotel room". AllMusic referred to Skinny Puppy's music as "primal" and " Kraftwerk gone netherworld", going on to state that unlike the bands that followed in their wake, "Ogre and Key knew how to craft tunes and marry them to the most ingenious of sound patterns". Some of Skinny Puppy's more recent offerings have been placed in genres such as glitch and intelligent dance music.  Ogre said in an interview with the Auxiliary Magazine in June 2013, "there is a very military side to Industrial music, and we are far more in the psychedelic side."
