Gradius NEO Imperial (グラディウスNEO -IMPERIAL- Guradiusu NEO Imperial ) is a horizontally-scrolling shooter game developed and published by Konami on March 1, 2004 for mobile phones, and was released on NTT DoCoMo's FOMA 900i line of phones in Japan.
In contrast to all other Gradius games, the player controls the opposing force through the use of a customized version of the Big Core. However, since the Big Core in this game is a rogue ship escaping from the Lars Empire, which is the enemy in Gradius NEO, players will not fight against the Gradius Union.
- Stage 1: Lars Empire Base
- Stage 2: Space Highway

- Stage 5: The Neutral Zone
- Stage 1: Big Core
- Stage 2: Satellite Core Mk. II

Big Core Custom is successful in escaping from the Lars Empire after destroying Genocide Core. Sadly, the Force Viper destroys Big Core Custom, not knowing that it was rogue and only making to escape from the Lars Empire. Big Core Custom's wreckage is then pulled towards and burns up in the atmosphere of the nearby star.
- The Zebra and Wolfar enemies in the game bear some resemblance to the R-9 Leo from R-Type Leo and the Silver-Hawks from the Darius series respectively.
