Valiant Comics is a comic book imprint published by various publishers since its inception with Voyager Communications, Inc. in 1989, later Acclaim Comics, Inc. Its assets were purchased from the bankruptcy of Acclaim Entertaintment (Acclaim Comics' parent company) by Valiant Entertainment, Inc. in 2007.
In the beginning, the Valiant Universe was a reflection of Jim Shooter's vision for an ideal comic book universe: character-driven, strong continuity with emphasis on science fiction, long-reaching consequences and internal consistency. Valiant was the first company to attempt to follow a real-world timeline, in which events in the comics occurred at a pace similar to their publication schedules. The company writers adhered to real-world science as much as possible. No matter how powerful the characters became, they were still affected by friction, Newton's Laws of Motion, Einstein's laws of relativity, etc.
