Knuckles using the Double Punch
Punch twice while advancing forwards.
Double Punch (1･2パンチ 1 2 Panchi?, lit. 1-2 Punch) is a move performed by Knuckles the Echidna. It first appeared in Sonic Advance 2 and later in Sonic Battle and Sonic Advance 3. It is a basic punch attack Knuckles gives to his enemies and is a variant of the Punch Attack.
The Double Punch is similar in performance to the Punch Attack, but rather than a three-hit combo, Knuckles only delivers a one-two jab with his left fist and then right fist to the foes in front of him. Also in gameplay, instead of the player having to press the Action button in succession to execute all three hits like in the Punch Attack, the player only has to press the Action button (or rather B button) once and Knuckles will automatically perform the full Double Punch combo.
Sonic Advance 2Edit
In Sonic Advance 2 Knuckles can only perform the Double Punch when moving forward. Once moving forward, the player can press the B button and Knuckles will use the Double Punch on the enemies in front of him
The Double Punch is the name of Knuckles' Dash Attack in Sonic Battle. However the move has a different appearance that it does in Sonic Advance 2.
Sonic Advance 3Edit
In Sonic Advance 3 the performance and execution of the Double Punch remains the same, but now Knuckles can perform the Double Punch while standing still, but trying to perform while moving it will cause Knuckles to stop.
Knuckles using the Spiral Attack
Sends Knuckles' fists forward, straight through enemies while he continues to run
In order to perform the Spiral Attack, Knuckles must perform the Double Punch while in Boost Mode, which can be reached by running at high speeds for a certain amount of time or using a Dash Panel. The resulting speed from the Boost Mode will then transform the Double Punch into the Spiral Attack.
When using the Spiral Attack, Knuckles will launch himself spinning through the air for a short time, while keeping his fists in front. This increases Knuckles' attack range, and the force from the speed will engulf his fists in fire. Foremost however, the Spiral Attack allows Knuckles to maintain the speed he is running at and remain in Boost Mode, unlike the normal Double Punch which would make Knuckles slow down.
