Rogue

Rogue is an unofficial, unobtainable fruit that cannot be purchased or found in normal gameplay. It has no physical fruit model and no icon — the game displays its internal ID, Rogue-Rogue, in place of an image. Rogue is the very first secret fruit ever added to Blox Fruits, created by developer Norp (Norperz) as a personal developer tool. It can only be accessed by typing the command /test4 in-game, making it completely off-limits to regular players. The fruit has just two moves, both of which instantly eliminate anything they touch with no cooldown, effectively making it a one-shot weapon with infinite uptime. Rogue is inspired by the Mori spell from Rogue Lineage. It holds a unique place in Blox Fruits history as a piece of developer lore that the vast majority of players will never see in action.
