One of the leaders of the Natives, Negishi seems like a fun loving person despite the deep respect ZECT offers to him. When he first meets Tendou, he almost admires Tendou, asking if he can be Tendou's fan. Despite his innocent look, Negishi actually has his own agenda and later carries it out once the Worms had been almost decimated. Believing Natives and humans would be unable to co-exist, Negishi sets up the plan to turn all of humanity into Native and thus achieve his ideal peace. To that, he placed Mishima as leader of ZECT and disposes Riku Kagami. However, Negishi didn't count on Tendou's words to sway his comrades to have second thoughts of his plan. In the end, Dark Kabuto manages to capture him, dragging him inside the TV studio explosion that killed them off.
