Appearance

Prototype is a doll-like robot with white casing and a floating head adorned with four crystalline horns. The larger, bicuspid red and yellow horns protrude from the top of his head, while the smaller blue and purple horns point out from the bottom. His dark blue eyes have hot pink highlights, and his default expression is neutral with a slightly open mouth. The back of the head is missing its casing, revealing four exposed wires which are in matching colors to the horns. The face plate is fully removable, revealing a different face underneath, which is gray, with circular 'eyebrows', the same color eyes as his faceplate, but this time looking up, two lines for a 'nose', and a grimaced mouth showing sharp teeth.

The torso is all white, and the arms have four claws each, matching the colors of his horns (thumb being red, index being yellow, middle being blue, pinky being purple). The left arm is mostly missing its casing, exposing grey metal plates underneath. The legs are identical and have grey sock-like metal plating on the bottom half, with visible bolts on the exposed metal areas.

In their Halloween appearance, they wear the Reverse Beartrap from the Saw franchise on their head, and their horns and claws are a darker shade of the original colors.

In their Christmas appearance, they swap out their color palette for one resembling candy cane colors, their horns being colored red and white and the exposed metallic sections of his body being maroon rather than gray.

In their April Fool's appearance, they have GLaDOS from Portal in the form of a Potato on their face, the Aperture Science logo on their chest, and blue and orange horns, as well as their claws.

In his Valentine’s Day appearance, their horns are changed to various shades of pink, and they don a pair of yellow cupid-esque wings along with a quiver full of gold arrows around their waist.

Description

Personality-wise, Prototype is a curious and happy character, with them rarely displaying negative emotions in their dialogue. This curiosity can occasionally be detrimental, as seen when they recklessly smash open crates possibly full of Knived Voombas or Glowing Red Teddies. They can occasionally be extremely logical, something that is not always appreciated, as seen in interactions with Bive and Mozelle. They often study and record information about the other characters, usually without their consent. Their speech is occasionally interrupted by errors and glitches due to their somewhat unfinished and aged state.

Interactions

Prototype spawns in the Find The Path floor sitting on a power box at the end of the level. When activated at the end, Prototype walks over the full path revealing which tiles should be walked on. He then enters the elevator saying "Ohh!" and "What's this?".

If MR is present in the elevator, or if the elevator is full, Prototype will walk to the end of the path, move to the side of the elevator and fall down the map, making the metal pipe falling noise after hitting the ground, similar to the first falling elevator in the Elevator Shaft floor and the sound heard in Happy Birthday? when FleshCousin leaves through the top vent. However, he doesn't die and he infinitely walks in a straight line until the floor ends. If the floor ends when he's walking on the path, he will not enter the elevator. It's also possible for him to accidentally fall into the abyss while going from a path tile to the platform that the elevator is on.

Prototype will exit the elevator on Cardboard Mansion, Slide 4 Admin, Intense Obby, Ballpit, Two Stud Camp, Jermpop Factory, Infected Apartment, Skyblock, 3008 and Happy Home Party. Once sitting on a log in Two Stud Camp, Prototype will throw anything he is holding into the campfire, excluding Scag.

If the elevator enters the Floppy Shoppy floor, he will exit the elevator but only to pick up Scag, allowing her to enter the elevator with him as well. He will also leave the elevator to pick up crates from certain floors and the trash can from the Reddy's Underground Diner floor.

He responds negatively to being shot, but will not attack players that do so. Even though he states otherwise, snowballs cannot damage him and neither can other projectiles.

Prototype will accept almost all items except for the Magic Mirror, Wet Cement, Kitty, or Gas Mask.

Crates

Crates are elements that spawn in specific locations on certain floors with a random chance. If a floor has a crate on it, Prototype has a chance to leave the Elevator, say some dialogue, pick up the crate and bring it back. If Prototype is already holding at least four object, including Scag, he will not pick up a crate. After an unspecified amount of time in the elevator, Prototype will either crush open the crate if it is wooden, releasing its contents, or simply drop the crate on the ground if it is a milk crate. There is a trash can full of pictures of Gregoriah in Reddy's Underground Diner that can be picked up by Prototype, but Prototype will only drop this trashcan into Two Stud Camp's campfire (spilling and burning the photos in the process) and will not drop it on his own, unlike with other crates.

There are currently eleven known wooden crate variants:

• Normal (Brown)
• White
• Red (Pale and Pure)
• Blue
• Green
• Yellow
• Black
• Pink
• Purple
• Magenta
• Gray

All types of wooden crates have a uniform appearance in the game, a cube with a wooden texture. Each face is indented and the horizontal faces have a single diagonal plank of wood across the indent, while the vertical faces have two diagonal planks in a cross shape.

The milk crate variant appears as a dark blue milk crate with a mesh design and nothing inside.

The trash can variant appears as a grey metal trashcan filled with a bunch of identical pictures of Gregoriah.
