Luka

Luka is the main character for most of the Geniuses books and is the leader of the group. He has enormous strength, and is made up of super-compressed plasma with a solid coating. Therefore, Luka has a decent magnetic field and when close to him, you will feel a small tug toward him due to his gravity (0.05 G). Luka has around the mass of the Statue of Liberty.

In the Origin and Books 1-4
At this stage, Luka is barely mentioned. He is the oldest of the Geniuses, and started off normal. Luka grew up in a gym, and became very strong. Audrey had to shut him in the trunk with iron chains to prevent him from escaping. When Luka was released, he immediately claimed leadership and started the weapons factory.

Luka is barely mentioned at all in books 1 and 2. All we know is that he developed his plasma powers by nuclear fusion in his liver, causing a plasma flood to speed through his body and eject his blood out of his mouth. In Book 3, Lon says that in Book 4, Luka will be the main character. In book 4, Luka fires a blaster, killing the Tayusins on Trappist-1e.

In Books 5-7
This is deemed the “Golden Age Of Luka”, and this is when Luka is at his full power. Luka supported the Deep Sea Destroyance and raged when Earth fell to the Tories, to take it back years later. In book 7, Luka invents a machine that destroys the asteroid that threatens to kill all life on Earth.

Book 8 and Geniuses Evolution
In book 8, Luka helps to make short-term solutions to the Red Giant Crisis, including EMBPS, and Planet Shifting. All of these are thwarted, and Venus returns back to its original state, while Earth and Mars become moons of Jupiter. Soon, EMBPS, Ganymede, Titan, and the Venus system flee the solar system to migrate to Acen. In book 9/Series 2 book 1, Luka falls into a deep sleep, frozen in a hypersleep chamber. He only wakes up when Lon dies, and celebrates after the Universe is saved. From then on, Lon will return to the Main Character position, and Luka will downgrade to a Major Character.
