Van Broken Biology

The organism is unique, a colonial one. Comprised of dozens of cloned versions of itself, the organism was able to build complexity. The organism is comprised of a vast underground network of nerve-like rhizomorphs and mycelia. After it's reached a certain size, it was able to gain sentience, possessing the ability for complex planning and reasoning.

Due to its unique biology and sentience, the organism is unable to verbally or visually communicate or interpret. It is also usually an immobile organism, unable to move under its own weight and power. Because of the unusual rhizomorphs and Mycelia, damage to them inflicts damage on the Fungus. Sustained and heavy damage can leave the fungus in a hibernation state, attempting to hold its sentience together. Severe damage can leave the organism bereft of its sentience.

Because of its unique biology, the fungoid is able to acquire more computing power with the more land it takes. As it gains more space to grow and spread its rhizomorphs, it's eventually able to gain more intelligence, learning skills from its opponents. It's distributed mass also means that the fungoid is difficult to kill. Separating root systems can be dangerous however. Once a root system is separated, it'll lose its sentience and start rampaging. If it's large enough, it'll develop a separate consciousness from the original fungoid becoming lost to it.

The fungoid is able to grow a weak fruiting body, able to move under its own power once ripe. The design of the fruit is up to the fungoid, being able to create its own designs or appropriating others once it's taken the appropriate DNA. By consuming the DNA of other creatures, it can appropriate certain biological designs, under the premise that it requires more to create another fruiting body like it. Fruiting bodies are cheap and easy to make for the fungus, but controlling more than one requires them to be connected to the main mass. Too many of them unconnected means they can go wild and rampage. Growing a fruiting body that's too large can result in it gaining sentience and separating from the fungoid.

The Fungoid itself has only static defense to defend itself, producing clouds of brown spores to cover the area. The spores are generally noxious and will ward off animals. The Organism is able to multi-task well, owing to its unique neural network. This means that it can manipulate a fruiting body from afar, while having guardian fruiting bodies at home. The fruiting bodies can only last so long however, decaying within hours of them separating. Having a dedicated cord to it from the main mass will solve the issue.

Basic Fruit Designs.
Eater: The Eater is full of growth hormones and enzymes, being comprised mainly of gnarled root-like tissue. It's able to attach to surfaces, digging into the material by eating into the substance. It can also use this offensively to dig into tough materials like steel and plastic.
Toxic: It's a bloated fungoid with sharp claws, with a large swishing belly of stretched tissue. This fruiting body is especially weak, but it's able to roll due to its girth, making it the fastest of any land-dwelling fruit minion. The liquid inside their extended bellies are a complex series of mycotoxins. Able to soak through the skin, it can cause a wide range of effects from hallucinations or infirmity. The effect worsens if the liquid gets in the bloodstream through the claws.
Smoker: This particular fruiting body is set up like a chimney, constantly able to produce clouds of spore from holes in its back as it stomps around. These are durable and small, being able to work tools and in rough conditions. They're used to spread the fungus to appropriate surfaces.
