Big Arm

Big Arm (known as the Squeeze Tag Machine in Sonic the Comic) is the final boss of Sonic the Hedgehog 3. It is the last of three bosses fought in the second act of Launch Base Zone.

If Sonic 3 is locked on to Sonic & Knuckles (i.e. in the game Sonic 3 & Knuckles), then Sonic (or Tails) will skip this boss completely, but Knuckles will still have to fight this boss with the Egg Robo piloting it.

The Big Arm is a large modified Egg Mobile piloted by Doctor Eggman with spikes on its top and two big hands for grabbing Sonic (or Tails or Knuckles), rolling them into a ball, and slamming them down. Normally the player's only real chance to attack this boss is when it swoops across the screen. The player must make a well-placed Spin Attack to attack the cockpit - too high and the character will hit the spikes, too low and they will be grabbed by the hands.

Attack Pattern
The Big Arm will usually just try to grab the character, but after 4 hits, it will fly to the top if the screen and it can't be hit. It will come down and sweep the bottom of the screen so the player as to jump to avoid it.

Sonic the Comic
In Sonic the Comic, Robotnik pilots the machine, here referred to as the "Squeeze Tag Machine", when he invades Sonic's Secret Underground Base in the Emerald Hill Zone. The machine is built so solidly that Sonic cannot damage it. Luckily, he is helped by Knuckles, who cracks the small windscreen with a punch, weakening it enough for Sonic to tear the top of the machine off with a Spin Attack.

Trivia

 * If the Big Arm grabs a character while in their Super form, the character will lose their rings, and thus lose their Super form. But if a character is in their Hyper form, it will create a Spring sound effect.


 * If a character is in their Super or Hyper form, they will be able to damage the Big Arm when it comes down to sweep across the platform.
