Story-related, cannot be missed.
See Super Sonic for a detailed walkthrough of the game.

After you complete the Ice Cap action stage, you will encounter Knuckles in the Mystic Ruins area, near the waterfall. You will have to fight him. After you defeat him, the trophy will pop during the ensuing cutscene. At this point you can quit the Sonic story and play Knuckles’ story, if you like.
