Libra is a fictional character, a supervillain appearing in comic books published by DC Comics. He first appeared in Justice League of America #111 (May-June 1974), where he formed the first incarnation of the Injustice Gang (though there had been other villain groups with similar names, like the Injustice Society and the Injustice League). Libra made his return with a leading role in Final Crisis in 2008.
Libra's only major appearance, prior to his appearance in Final Crisis, was in Justice League of America #111–112, in 1974. In 2004, he made a brief cameo in the JLA/Avengers crossover (#4) by Kurt Busiek and George Pérez.
Grant Morrison, the writer of Final Crisis, explained the reason for picking an obscure villain:
In May 2008, his appearances were reprinted in DC Universe Special: Justice League of America at the same time as he was reintroduced, along with the Human Flame (a Martian Manhunter foe who appeared in Detective Comics #274), in Justice League of America #21. He returns, apparently retaining the full might of his godlike status, to lead a new and final incarnation of the Secret Society of Super-Villains, this time offering to every villain, from simple costumed crooks to major ones, the realization of his/her fondest wish.
Mister Sinister, or just Sinister, is a fictional supervillain appearing in American comic books published by Marvel Comics. The character first appeared in Uncanny X-Men #221 (Sept. 1987) and was created by writer Chris Claremont and artist Marc Silvestri.
Mister Sinister has appeared in a number of X-Men titles including spin-offs and several limited series. The character has also featured in associated Marvel merchandise including animated television series, toys, trading cards, and video games.
IGN's list of the Top 100 Comic Book Villains of All Time ranked Mister Sinister as #29. In 2008, Sinister was ranked #6 at Marvel.com on their list of Top 10 X-Men villains.
Writer Chris Claremont conceived Sinister as a new villain for the X-Men, having felt "tired of just going back to Magneto and the Brotherhood of Evil Mutants and the same old same old" Claremont recalled:
Mister Sinister debuted in the title Uncanny X-Men, briefly mentioned by Sabretooth during the Mutant Massacre crossover as the leader of the Marauders who had sent them to slaughter the Morlock population. In the following issue, the X-Men member Psylocke picks up a shadowy mental image of the Marauders' "Master" from Sabretooth's mind. Mister Sinister finally appeared on-panel in issue #221 (Sept. 1987). The character plays a major role in the Inferno crossover, where it is revealed that Sinister cloned Madelyne Pryor from Jean Grey for the purpose of having her conceive a child with Cyclops, their son Nathan; Sinister is also revealed to have manipulated Cyclops' life since early childhood. After a battle with the X-Men and X-Factor, the villain is apparently destroyed by Cyclops' optic beam.
Sinister is a death metal band from Schiedam, the Netherlands, assembled in 1988, disassembled in 2003, and reassembled in 2005. They have released twelve albums, most recently Dark Memorials in 2015.
HeroClix is a collectible miniatures game that uses the Clix system that centers on the world of superhero comic books, especially the Marvel and DC Comics universes. Players construct teams of comic book heroes, villains, or characters from various video games series such as Street Fighter, Gears of War, and Halo and engage in a turn-by-turn battle on grid maps based on various storyline locations. The Game was originally designed and produced by WizKids, but was discontinued in November 2008 when WizKids owner Topps shut down their HeroClix line. In September 2009, collectible toy producer National Entertainment Collectibles Association (NECA) purchased some of the WizKids' intellectual property from Topps, including the HeroClix rights and then soon after began to produce and sell new HeroClix series.
