Heat Arms (ヒートアームズ?) is a mini-boss from Sonic & Knuckles, as well as its locked-on form, Sonic the Hedgehog 3 & Knuckles. It is encountered in the first act of Lava Reef Zone.

Battle

At the start of the battle, Heat Arms raises a pair of large antennae. Both antennae shower the screen with shots, then lower to make way for a giant hand. The hand follows the player's movements for some time before trying to crush them. This process repeats until the giant hand is destroyed, which takes six hits.

If the antennae are hit four times each, they will be destroyed so only the hand can attack. The shots fired by the antennae can be deflected by a shield.

Trivia

  • The hand portion of Heat Arms resembles the hands of the Great Eggman Robo.
  • The antennae make a reappearance during the boss battle against the Mega Octus in Sonic Mania's Oil Ocean Zone, where they appear when Eggman's submarine surfaces. They function and are destroyed in the same way as they are in Sonic & Knuckles.
