Lyric is a giant and monstrous snake with green scales and brown spots in places. He wears a sophisticated brown robotic chest armor with a pair of three-fingered arms. He has a rattle-like object on the tip of his tail that is a gray claw, essentially resembling a hand.
Lyric is described as darker, more foreboding and more power-hungry than Doctor Eggman. Having been driven mad by power, Lyric is an evil, ruthless, dangerous, pitiless and remorseless monster, and an extremely tech-savvy mastermind. He is also rather vengeful, spending his time in his prison to plan his revenge.
