The Robots are the main antagonists of the 2003 video game SpongeBob SquarePants: Battle for Bikini Bottom and its 2020 remake SpongeBob SquarePants: Battle for Bikini Bottom - Rehydrated. They are a group of robots built by Plankton who went rogue and cause amok throughout Bikini Bottom.
Plankton builds an army of robots through his new invention called the Duplicatron 3000, intending to steal the Krabby Patty secret formula and take over the world. However, Plankton accidentally leaves the "OBEY PLANKTON" switch set to "DON'T OBEY PLANKTON", resulting in the robots overthrowing him and invading the different places of Bikini Bottom, vandalizing and conquering until the world submits to their rule. SpongeBob, Patrick, and Sandy team up to defeat the robots and save the city.
Once the areas are cleared, SpongeBob and friends enter the Chum Bucket, where Plankton admits his mistake and tries to flip the command switch. A robotic replica of Plankton reveals himself as the real leader of the robots and orders his bride, SpongeBot SteelPants, to destroy the heroes. After a lengthy battle, SpongeBob destroys SpongeBot, while Robot Plankton is "defeated" when multiple Robot Planktons spawn from the Duplicatron 3000 and get in a mass argument. Sandy informs SpongeBob and Patrick that robots still run wild outside, although Patrick insists to celebrate their victory with ice cream, which SpongeBob agrees to.
The most basic enemy. They are small with cube bodies, red eyes, and move on a single wheel. When approached, they use a black stick with a red top that conducts electricity to attack. They are fast but die from any attack.
Robots wielding giant hammers as right arms, which are made of bamboo poles and a giant piece of ham with "Mer" written on it. In Rehydrated, the hammers are made of metallic blocks painted like ham.
Slower but durable robots that carry large containers of tartar sauce on their backs. They attack by using nozzles attached to the container to shoot three rounds of tartar sauce at the player.
Small robots with large mouths, attacking by either biting or spraying poisonous fumes. They tend to attack in hoards, although like the Fodder enemy, they die in one hit.
Disc-shaped robots resembling green and purple flying saucers with five gloved hands around the circumference. They attack by spinning, slapping the player when hit. SpongeBob and Patrick can defeat them by ground-pounding, while Sandy can use her lasso to take them down.
Submarine-like flying robots with large gloved hands on their top. When they target the player, they throw torpedoes that spew water. While possible to take them out directly, it is possible to use distant attacks to take them out instead. Rehydrated marks a red circle on the ground where the torpedoes are going to land.
Robots with glasses and umbrellas using a propeller to fly. They summon a small storm cloud that chases the player and strikes them with electricity. SpongeBob can defeat them with his Bubble Bash or Cruise Bubble techniques and Patrick can throw tikis at them.
Small bomb-like robots that let out beeping noises when the player approaches, chasing after them until they self-destruct. Attacking them does not defeat them, rather they are thrown back and then explode.
A large sleeping robot casting light from their antennae. When something enters the light, they wake up and shoot lasers at them unless they are quiet enough. When a Bubble Bowl is thrown, they use the laser to direct it away. SpongeBob can sneak towards the robot to destroy them. But since Patrick and Sandy have no sneaking mechanic, they must rely on using distant attacks.
Large robots dressed as cowboys wielding dog houses. When approached, they summon Arf Dawgs from the doghouse. When attached, they warp to another location. They take three hits to destroy, although the Cruise Bubble destroys them instantly.
Small dog-like robots that blow up after a certain amount of time similarly to the Bomb-Bot. They are the only non-boss robots not to drop Shiny Objects.
Small cylinder robots that emit powerful gamma rays from their green eye. The ray is harmless while green but soon turn yellow and cause damage.
Trios of robots with helicopter hats and ride on pink floaties. When they spin, the floaties emit flames. Each Tubelet can be defeated easily, but all three must be defeated or else they will respawn and retaliate with a large blast.
Large and powerful robots that use oil to create bubbles, which they use to shoot at the player and cause the floor to become slippery, or protect themselves in a large shield.
The first robot boss fought in the Poseidome Colosseum, resembling a massive Sandy. She attacks by karate chopping, slamming on the ground, or performing the "Old Clothesline Move". SpongeBob and Patrick can defeat her by causing her head to pop off and electrocute it on the scoreboard.
The second robot boss fought in the Industrial Park, resembling a massive Patrick. He can breathe ice that temporarily freezes SpongeBob and Sandy, and spits out a sludge coming from his toxic ice cream cone. His weak spot is a note that reads "Kick Me Here!" on his back, although as the phases continue, toxic waste is brought into the arena that covers it, forcing Sandy to summon crates and SpongeBob to use the Bubble Bowl.
A cut boss from the original console game but appears in the GBA version (as "Squid Vicious") and in Rehydrated. In Rehydrated, Robo-Squidward only appears in the multiplayer horde mode where he summons waves of enemies to battle the players on the different islands. After clearing some islands, one of his tentacles is destroyed. Once all 26 islands have been cleared, the last tentacle is destroyed and the boss falls into the goo.
