Heat Arms ( is a mini-boss from ヒートアームズ ) ? , as well as its locked-on form, Sonic & Knuckles Sonic the Hedgehog 3 & Knuckles. It is encountered in the first act of Lava Reef Zone.
To start the battle, Heat Arms raises two shooting arms. Both arms shower the screen with shots, then lower to make way for a giant hand. The hand follows the player's movements for a while before trying to crush him/her. This process repeats until the giant hand is destroyed, which takes six hits.
If the shooter arms are hit four times each, they are destroyed, so only the hand can attack. The shots fired by the shooter arms can be deflected by a shield.
The hand portion of Heat Arms resembles the hands of Kyodai Eggman Robo.
If playing as Tails, the hand can crush the player even in Super form.
If Sonic is in his Super or Hyper form, he can just stand there, and the main hand will just end up destroying itself when it tries to crush him, taking damage until it retreats for another round.
