 
Sega vs. Snk: Black Sun is a crossover fighting game published by Sega and developed by SNK Playmore, releasing for the Nintendo Wii and Xbox 360 consoles. It utilizes a 2.5D fighting environment with 3D character models (similar to Tatsunoko vs. Capcom's) in a mixture of both 2D and 3D backgrounds purposely drawn by Daisuke Ishiwatari (Guilty Gear). Its balanced roster of 100 characters are sorted in what brand they appear from (ex. Sonic the Hedgehog and Akira Yuki for Sega, Kyo Kusanagi and Ryo Sakazaki for SNK), and speaking of which, most fighting is done as 2-on-2 versus formats, being adjusted towards a three-button control scheme (most similar to Tatsunoko vs Capcom, again). Many could say that Black Sun is an inspiration to TvC, and some could say that this is a complete ripoff of said game... This is an idea, so only the inspiration part would matter the most... Okay, maybe not! :) Main illustrations are drawn by Shinkiro and co-helped with Yuki Kato.

Original Characters[]
- Yoshitaka Ayanokoji (Voice actor: Yuki Kaji): A teenage boy with demonic powers and a sharp wit enlisting the strong help of the Snk and Sega universe to defeat a dark and powerful entity. He is also a starter character.
- Incubus (Voice actor: Joji Nakata): He is a demon God who despises all humanity and predicts a very gruesome death for Yoshitaka's well-being. Incubus knows that he has joined forces with the Snk and Sega universes together to try and defeat him once and for all. He is the final boss of the game, and his stage "Oblivion" is a hidden, playable arena.
Music Development[]
Throughout the game, there is music composed by the likes of Satoshi Ise, Tate Norio, and Yuzo Koshiro. One can simply notice that the pieces of songs were taken from fan-favorite titles such as Sonic CD, Guilty Gear XX, and BLEACH. All of these songs (excluding Virtua Fighter themes) were tweaked up a bit and have better recording than the original.
