Heyla, all. No, I am not dead , and neither is this story. I just haven't had much time to sit down and write. To give you guys something to read while I hammer the next chapter out, I give you the original concept that I made on the League forums. Please feel free to review it and give me some pointers.


Alexei, the Possessed
Melee, Fighter

Stats:
All of these start out as his stats at Level One. The second number is the base at Level 18.
Health: 450 (+95/lvl) 2160 at Lvl 18
Health Regeneration: 6.75 per 5 sec (+.7/lvl) 19.35 per 5 Lvl 18
Mana: N/A
Attack Damage: 50.5 (+3.4/lvl) 111.7 Lvl 18
Ability Power: 0 (0/lvl)
Attack Speed: 0.672/sec
Attack Range: 125
Movement Speed: 360
Armor: 17.5 (3.3/lvl) 76.9 Lvl 18
Magic Resist: 30 (1.25/lvl) 52.5 Lvl 18
These stats are probably going to be weird late game. Again, read everything before commenting please.

Resource:

Alexei uses Concentration as a resource, shown as a purple bar underneath his Health, going from 100 down to 0. For every ability Alexei uses that strikes an enemy, he loses 10 Concentration. Every time Alexei is struck by an enemy ability, he loses 5 Concentration. When he reaches 0 Concentration, his Ultimate becomes usable. After his Ultimate ends, Alexei returns to 100 Concentration. Bar becomes visible after Alexei puts one rank in his Ultimate, starting at 50 Concentration. His Concentration will increase slowly (5 every 3 seconds)back up to a cap, the caps being at 25, 50, 75, and 100.
Thought this would fit, considering his lore. If it seems too weird, could always change to Rage or maybe a Ferocity-esque resource. The slow increase of his resource is to keep people from keeping his Concentration at 0 to save it for a gank or to counter-gank. I wanted his Ult to seem like something you should use to turn the tide of a fight.

Abilities:

Passive: Black Rage
For each blow Alexei lands, he gains 5% of his base Attack Damage as Bonus Attack Damage for 4 seconds. Stacks 6 times.
Like Jax's passive, but for AD. Should help early game with beating off ganks and for last hitting.

Q: Red Lance/Crimson Storm
Alexei throws his blades forward, dealing 60/75/90/105/120 (+70 % AD) physical damage to all targets hit. Upon reaching max range, the blades return, causing 30/45/60/75/90 (+60 % AD) physical to all targets hit. Targets after the first take 15% reduced damage, minimum of 40%. (Range 800, Width 150).
When Possessed, for 3 seconds after the returning of his blade, Alexei can launch his blade in an area attack, dealing 100/120/140/160/180 (+75 % AD) physical to all targets hit and slowing them by 15/19/23/27/31 % for 4 seconds. (Range 400)
Cooldown: 7/6.7/6.4/6.1/5.8 seconds
A pretty simple ranged poke. Numbers could be tweaked, but I believe it's a pretty good ability with the secondary ability. Secondary ability would be like a large version of Riven's stun, he would throw the blade out out and it would circle around and return.

W: Raging Thirst/Tribute
Alexei's next basic attack causes an additional 15/22/29/36/43 (+12% of maximum Health) physical damage and healing himself for 50/55/60/65/70% of the damage dealt.
When Possessed, Alexei can activate this ability again within 4 seconds to heal all allied units besides Alexei in 600 range for 60/70/80/90/100% of the health received from Raging Thirst, and increasing attack speed by 20% for 7 seconds.
Cooldown: 6/5.5/5/4.5/4 seconds
Alexei's spammable ability, especially at max level. The heal isn't all that much, but is great for drawn out fights. The secondary is going to be good for team fights.

E:Painful Dash/Pain Wave
Alexei dashes towards target area, causing 80/105/130/155/180 (+70 % Bonus AD) physical damage in a 300 range, 80 degree cone in front of him. (Range 400)
When Possessed, Alexei can dash a second time within 4 seconds, causing 90/110/130/150/170 (+80 % Bonus AD) physical, and doubling the wave range to 600. The conal area remains at 80 degrees. Damage is the same for all targets hit.(Range 400)
Cooldown: 10/9/8/7/6 seconds
Another poke, with the potential to be a good chase or escape ability. Again, the numbers could be tweaked.

R:Final Release
Alexei allows the Daemon Vashirik to surface, gaining 350/500/650 max Health, 30/55/80 Attack Damage, and allows all of his basic abilities to enable proc abilities for additional effects. Lasts until Concentration goes back up to 100. Concentration will increase by 5 every second in combat, and 10 every second if Alexei has not taken or dealt damage within 3 seconds. Requires a .5 second channel. Requires Alexei to be at 0 Concentration.
Alexei's Ultimate, functioning like Nasus' and Renekton's Ult. The interesting thing about this Ult is the choice of using an ability twice for additional effects. Model becomes slightly larger and grows horns and translucent wings, with a dark purple aura radiating from him. The dual katanas also become a single weapon, larger than the two blades individually. A note on the Proc abilities: Cooldowns begin after the secondary is used or fades.

Hidden Passive: When facing a Void champion on the other team, Alexei gains new taunt emotes specific for the closest enemy Void champion. Reasoning for this is that Daemons and Voidborn are bitter enemies.
Cho'Gath: The bigger they are, the easier they die.
Kog'Maw: Come chew on these! *flips swords in a backwards grip and presents them, then flips back to his regular stance*
Kha'Zix: Try and eat me? You don't have the stomach.
Vel'Koz: I'll teach you something you won't forget, mongrel.
Malzahar (not technically Voidborn, but still a Void champion): Envision this, Seer. *points and draws blade across his neck*
Kassadin (again, not Voidborn but Void champion): Think the Void is scary? Try seeing a Daemon.
