Lyric the Last Ancient

Lyric the Last Ancient is the main antagonist and final boss of both Sonic Boom: Rise of Lyric and Sonic Boom: Shattered Crystal. He is the last of a benevolent race called the Ancients, but went mad with power and turned on his peers to create a world of twisted metal and robots using the power of his people's crystals. Before he could carry out his nefarious deeds, however, he was imprisoned. Centuries later, Lyric was freed and resumed his plans, but was defeated by Sonic the Hedgehog and his crew.
