Guardian of the Master Emerald and protector of Angel Island, Knuckles the Echidna is a loner by nature and rarely cares for anything that is of no importance. However, when his friends are in need of help, Knuckles can always be relied on to leave his post and prove himself a faithful and good-hearted hero. Strong, serious and at times stubborn, he is known for having quite the explosive temper. When learning of Sonic’s defeat, Knuckles forms and leads a Resistance to fight back against the Eggman Empire, doing whatever he must to take back the world.
