Quotation1 Hand over those Master Emeralds! Give them to me! Quotation2
— Knuckles

Knuckles the Echidna is fought as a boss in the Dark story of Sonic Adventure 2. He is fought by Rouge the Bat, after clearing Mad Space.


The battle takes place in the large tower seen in the center of Meteor Herd. Eventually, the floor in the area will open, sending them into the air where movements and gliding are possible. The fight will continue on the sides of the tower when this happens, until the floor closes again.

Knuckles's battle is very complex. Should both combatants hit each other at the same time, they will repel each other without harm. The player thus has to attack Knuckles while he is moving. When fighting him on the tower structures, the key is to track Knuckles down and attack him. During the battle, Knuckles uses his Punch Attack in close combat and his Glide or Drill Claw when Rouge is beneath him. After Knuckles' health has been reduced to half, he will start using his two special attacks: when Rouge is close he can use his Hammer Punch, and when far away he busts out his Thunder Arrow which can hit Rouge anywhere. Four hits are required to defeat Knuckles. 


"I have no choice but to fight you now!"
—Knuckles when his health is lowered to half
"Now witness my power, take this!"
—Knuckles when using his special attacks
"I must protect the Master Emerald."
—Knuckles when defeated


  • The fight against Knuckles in the Dark story is identical to the fight against Rouge in the Hero story.
  • Along with Rouge, Knuckles is the only character boss not to be fought twice in the story.
