Editing Yu-Gi-Oh! Trading Card Game (section)

===Legal dispute with Beyond Comics===
In 2008, Beyond Comics Inc. and its founder Graig Weich filed a lawsuit in the United States District Court for the Southern District of New York against Konami Digital Entertainment Co., Nihon Ad Systems (NAS), 4Kids Entertainment, Upper Deck Company, and others, alleging copyright infringement, trade dress infringement, and unfair competition. The complaint stated that Konami and its partners had unlawfully copied the design of Weich's comic book character '''Ravedactyl''', created in 1993, in the design of the '''Elemental HERO Air Neos''' character from the ''Yu-Gi-Oh!'' trading card game and animated series.

According to the court filing, Ravedactyl had been widely promoted at industry conventions, including San Diego Comic-Con and MIPCOM, and featured in comic books, films, and toy prototypes. Beyond Comics claimed that Konami and NAS had direct access to the character and that Air Neos allegedly misappropriated multiple distinctive elements of Ravedactyl's design, including its helmet, wings, color scheme, and overall stance. The lawsuit also cited statements by ''Yu-Gi-Oh!'' creator Kazuki Takahashi, who had acknowledged drawing inspiration from American comic book superheroes when designing the "Elemental HERO" series, including "Neos", and that had Takahashi/other Konami staff had been at most of said events.<ref>{{Cite web |title=Beyond Comics Inc v Konami Corp |url=https://trellis.law/doc/district/4831479/beyond-comics-inc-v-konami-corp |website=Trellis Law |access-date=April 17, 2025}}</ref>
