Hi. I am a huge admirer of the Stranger Things Netflix TV Show. Thereby, I have created this guide for the Rek'Sai, which aesthetically feels the closest to the show's infamous monster -- Demogorgon.

Note: This guide/build is made for fun, and should be treated as such. For actual guidance, see other guides over there. However, if your sole interest is having as much fun as possible, try this assassin-like build and enjoy the show. Also, the base skin of the Rek'sai resembles Demogorgon the most (screeching noises), so, you don't have to invest anything to try this out.

Good luck and have fun on the Rift!

Passive: Insatiable Hunger

Being in combat, or taking any offensive action throws Demogorgon in rage, filling up the stored rage bar. When the bar is full, the Demogorgon is considered being Enraged. Upon going to the Upside Down, Demogorgon feeds off its own rage, healing self in the process (this action consumes the rage stored).

Q: Ferocious attacks/Sonar pulse

When in the Real World, Demogorgon is able to reset and empower its next three melee attacks, each followed by an outburst of physical damage to all enemies around it.

When in the Upside Down, the monster is able to send an echolocation-like signal in a direction, revealing enemies struck for the next few seconds, and dealing minor physical damage.

W: Reality Warp

Demogorgon is able to move between two dimensions at will. In the Real World, its interactions are the same as of the other habitants of this plane of existence. In the Upside Down, Demogorgon can no longer see or interact with the beings of the Real World directly, but moves at slightly higher speeds and can sense the prey's movement in the Real World in an area around it. However, it can be still targeted by enemies while in the dark dimension. Upon exiting the Upside Down, Demogorgon knocks up all the enemies on top of it based on the proximity, dealing some physical damage to them.

E: Devour/The Gate

When Demogorgon is in the Real World, it can bite a single enemy, dealing a sufficient amount of physical damage. When Demogorgon is Enraged, the damage will become heavy instead and will pierce through any form of resistance.

When Demogorgon is in the Upside Down, it can create the Gate, and swiftly pass through it. Furthermore, the Gate persists for an extended period of time, can be reactivated again after a short delay, and be destroyed by the enemy champions standing on the Gate.

R: Horrid Ambush

Passively, Demogorgon can sense the slightest wounds of its enemies from a tremendous distance. Actively, it will disappear to the Upside Down, becoming absolutely untouchable for a brief moment. Shortly after, Demogorgon will reappear, ambushing the wounded enemy and dealing immense physical damage to it, partially based on the enemy's missing health.
