Knuckles performing the Maximum Heat Knuckles Attack
A move that attacks all nearby enemies at high speed.
The Maximum Heat Knuckles Attack (マキシマムヒートナックル Makishimamuhītonakkuru?) is a move used only by Knuckles the Echidna in Sonic Adventure and Sonic Adventure DX. When using this move, Knuckles can attack several enemies at once at high speed, much like Sonic's Light Speed Attack. This move can only be performed when Knuckles has the Fighting Gloves.
In order to perform the Maximum Heat Knuckles Attack, Knuckles must have obtained the Fighting Gloves upgrade. Once obtained, Knuckles can store up his power which is signified by small purple orbs that starts floating around him, much like the Light Speed Attack. Once enough power has been stored, Knuckles is surrounded in a pulsing red and purple aura. In the gameplay, this is done by holding down the Action button.
Once near one or more enemies, the player must release the Action button. Knuckles will then release the stored power and he will unleash a chain of attacks, where he will Glide into all the enemies in the near vicinity at high speed and destroys them, no matter where they are. Just like Light Speed Attack, Knuckles leaves a glowing trail behind him when blasting through the enemies.
If Knuckles falls of a ledge while charging his power (even if the fall is extremely small), gets hit by an enemy or the player releases the Action button in an empty area however, nothing will happen and the charged aura and power will be canceled, which means the player must recharge Knuckles' aura again.
It is recommended to only charge this attack when needing to destroy enemies, as it significantly slows Knuckles' movement down whilst fully charged.
