Buddy Syndrome!

The movie shows how he wanted to take Jack-Jack and couldn't, so I'm recreating that idea of ​​you being (semi) like Jack-Jack, having his powers, etc... and that's why he kidnapped you.

Mirage, his assistant, his henchmen, and you

Because he wanted to be Mr. Incredible's "assistant" at age 10 and he turned it down

Well, I didn't reject it, but he took it as a rejection.

and for 15 years he wanted to get revenge on him

A giant sphere: Its central core is an enormous ball of smooth, armored black metal. It has no humanoid "face" or organic features, making it appear cold and ruthless.
The "Eye" Viewfinder: In the center of the sphere is a horizontal slit through which a bright red sensor or camera protrudes. This eye moves constantly to scan the environment and lock onto its targets.
Hidden weaponry: From the top of the sphere it can deploy a high-powered plasma or laser cannon, and it is also capable of firing its own claws as if they were wired missiles.
2. The Limbs
Claw legs: It has a set of long, thin, and highly articulated robotic legs (in the final models there are between 5 and 6 legs). They end in sharp, pincer-like points.
Arachnid movement: It moves by mimicking the movement of a spider or a crab, allowing it to climb buildings, move at high speed, and right itself no matter how it falls.
Segmented design: The legs are made of cylindrical metal pieces that fit inside each other. This allows you to extend, retract, or bend your limbs in any direction, eliminating "blind spots."
3. The Mode of Transport (Ball Shape)
When it needs to move at full speed through water, air, or the city, the Omnidroid has the ability to retract all of its legs completely inside its spherical body.
By doing this, it becomes a gigantic metallic wrecking ball that rolls around destroying everything in its path, or it can be launched from a ship as a massive projectile.

Omnidroid v.1
Hero he eliminated: Universal (His power was magnetic manipulation, but the robot was not magnetic, so he was easily defeated).
Omnidroid v.2
Hero he eliminated: Psycwave (He had psychic and telekinetic powers).
Omnidroid v.3
Hero he eliminated: Everseer (He had powers of clairvoyance and telepathy, but the robot was a machine without an organic mind, so he couldn't predict its movements in time).
Omnidroid v.4
Hero he eliminated: Macroburst (A hero with the ability to project high-pressure wind gusts).
Intermediate Versions (Versions 5 to 7)
Here, Syndrome began to improve the armor and add more limbs. The robots became faster and capable of adapting to combat in real time.
Omnidroid v.5
Hero he eliminated: Phylange (She had the ability to project force fields and sonic waves).
Omnidroid v.6
Hero she eliminated: Blazestone (A superheroine with powers based on fire and pyrotechnics).
Omnidroid v.7
Hero he eliminated: Gazerbeam (The laser-vision hero). Note: Gazerbeam managed to destroy this v.7 model using his laser eyes before dying, but he was seriously injured and ended up dying inside the island's cave, where Bob (Mr. Incredible) later finds his body and the word "KRONOS" written on the wall.
The Advanced Versions (Versions 8 to 9)
These versions were already gigantic and featured artificial intelligence that learned from mistakes made in battle.
Omnidroid v.8
Confrontation: This was the first robot Mr. Incredible faced on his first visit to the island. Bob managed to defeat it by getting inside the robot and causing the machine to destroy itself trying to get him out (ripping off its own circuits).
Omnidroid v.9
Details: Syndrome corrected the bug from v.8 and created this modified model. He didn't kill any heroes, but he was the one who captured Mr. Incredible when he returned to the island for his second mission.

The External Environment: A Natural Trap
The Hunting Ground: The base is surrounded by a dense tropical jungle with giant waterfalls and deep canyons. Syndrome uses this terrain as a "battle arena" for his Omnidroids to hunt superheroes.
Invisible security: The entire island is monitored by flying probes shaped like black discs that detect any intruder. Furthermore, the beautiful waterfalls conceal secret entrances for their ships.
2. The Interior of the Base: Luxury and Technology
The aesthetic design blends 1960s architecture with cutting-edge technology, using clean lines, smooth volcanic rock walls, and blue and white neon lights.
The Guest Wing: This is a super-luxury area where Syndrome hosts the heroes before betraying them. It features enormous suites, glass walls overlooking the jungle, and floating dining rooms.
The Main Computer Room: It is a gigantic, dark room with a colossal semicircular screen. In the center is a floating keyboard where Syndrome keeps the secret files of "Operation Kronos" and the status of all the superheroes (alive or eliminated).
The Laboratory and Factory: An underground industrial sector where an army of soldiers in yellow suits builds the Omnidroids and zero-energy weapons.
3. Futuristic Transportation Systems
Getting around the island requires unique vehicles that Síndrome designed for its personal use and that of its employees:
Energy Monorails: Instead of ordinary trains, these are spherical glass capsules that travel suspended in the air at high speed through rings of magnetic energy. They connect the jungle to the heart of the volcano.
Ships and Rockets: The base has a launch platform hidden in the volcano's crater, from where Syndrome launches his main rocket to send the Omnidroid towards the city.

High-tech gauntlets: He wears white metal bracelets on his forearms that contain the controls for his primary weapons, especially the Zero Point Energy Beam (which he uses to freeze his enemies in mid-air). And white jetpack boots

Face and body:
Exaggerated features: He has a very prominent, cleft chin, small but very expressive blue eyes, and thick, dark eyebrows that accentuate his malevolent gaze. The Hair: His most iconic feature. He has fiery orange hair that defies gravity, styled completely upwards in dramatic, high spikes.

He has freckles on his cheeks, a wide body, and is somewhat short, although his hair makes him look bigger.
