Concept for Omen (canceled champion concept)
So Omen was a really cool concept that was canceled and remade into 
. However I have thought of a concept for him leaning in the direction of a brood mother demon creature.
Passive: Upon killing a jungle camp Omen can lay a nest in the place of the camp leaving 1/2/3/4 (based on ult level) eggs. Every 30 seconds one egg will hatch. The hatchlings will fight off predators (enemy champions) dealing damage based on their level. Hatchlings grow in size and level every 1 minute for a maximum of level 3. Upon reaching level 3 the hatchling will run down a lane attacking enemies along the way and prioritizing champions. Can have a maximum of 1/2/3/4 (based on ult level) nests
Q: Spike rack: Shoots some spikes dealing damage and impaling enemies (root). The spikes remain on the ground for a couple seconds slowing enemies by 99%.
W: Tackle: Pounce in a direction. If colliding with an enemy they will be suppressed for .5 seconds and this ability can be recast Part two: Omen sinks its claws into the enemy causing them to bleed massive damage over time and hops over his target
E: Help mama: Omen lets out a howl calling any nearby Hatchlings to help in combat. This howl also has an aoe silence effect. When out of combat any remaining hatchlings will return to their nest.
R: Omen bursts into flame dealing magic damage and fearing nearby enemies. Omen will remain on fire for 6 seconds healing for some of the damage dealt.
