Plants of Trigun
The planet of the anime Trigun, Gunsmoke, is mostly powered by inter-dimensional beings called plants. The towns and villages of Gunsmoke use them to create energy. They are also used to generate water and food that are based on environmental needs. Humans invented these plants that are housed in a giant light bulb container. There are also independent plants that walk around in special containers. They have free will and can use their plant powers whenever they wish.
When looking at a plant, that are housed in the giant light bulb containers, they are feminine looking. Vash and Knives, two of the independent plants, are actually male and have distinct characteristics. They have longer life spans than humans. Vash is around 130 years old (150 in the manga), but looks in his mid 20s. They grow more rapidly than human babies.
Not only do they act different and grow quicker, they also have super human strength. The focus better as well as have high agility skills. Being more focused is good and makes them excellent marksmen. Vash has the telepathic ability as well as a higher IQ. Being a plant isn’t that bad.
Plants also have special ability to generate weapons. Vash and Knives both can create any powerful weapon from tehir bodies. While Knives has an array of blades, Vash can create the Agnel Arm. The Angel Arm is powerful enough to completely destroy an entire city.
Once an independent plant has reached a certain control level, they can merge with plant energies and manipulate them. Knive’s does this several times throughout the manga. Knives absorbs so much energy he created the ‘Ark’ and uses it to find the last plant life on Gunsmoke. He even tries to absorb Vash at one point, but fails. There are some independents that can mentally block being absorbed.
