Mecha Knuckles is the fifth boss battle in Sonic Advance, which takes place in Angel Island Zone. It's a pink echidna with yellow gloves, and is based on Knuckles the Echidna's appearance. The boss uses all of Knuckles' abilities, and it will also block Spin Dash and special attacks when in his regular position.
Do not attack it when he is Spin Dashing, or attempt to attack from the front while he is gliding. You can attack him in mid-glide from below. After it takes four hits (or three if easy mode), it will turn more aggressive, and it'll start to shoot missiles out of his mouth. The player must inflict a total of eight hits on this robot to defeat it (or six hits if in easy mode).
