Celebrate years of echidna excellence with the ultimate Knuckles adventure!

Knuckles the Echidna: guardian of the Master Emerald, defender of Angel Island, last of his kind, and--let's face it--Sonic's most stubborn friend. But what happens when the legendary protector meets a young, self-doubting would-be guardian in need of a mentor?

In this heartfelt, action-packed special, Knuckles takes on his toughest mission yet: mentorship. As he trains Trip, a new guardian-in-the-making, Knuckles faces his past, confronts what it truly means to protect, and proves that strength isn't just in the fists--but in character.
