Welcome to Gaia! ::

lol, sure. I'm gonna do the total league format for this.

Kleine Heiland =

Passive - Due to Kleine's inhuman perception, this champion dodges 25% of all basic attacks and takes 10% reduced damage from spells and abilities

Q - Prophecy of God
This ability allows for Kleine to predict the enemies next attack, and therefore totally block that next ability (spell shield). After the attack has been blocked, Kleine can go in for the temporary opening by activating the ability. His next basic attack on this target will do 80/120/160/220/260 increased damage.

W - Red Lady (skillshot)
If this attack hits an enemy champion, Kleine flashes a bright light from his palm and inflicts high damage on them (100/150/200/250/300) and their armor is shredded by 15% for five seconds. After this attack has landed, Kleine gains 20% increased movement speed for 4 seconds.

E - Pestilent Speech
Kleine starts to utter lie after lie and anyone he's facing during this temporarily active ability takes 10% increased damage from all attacks. He gains a shield of 70/110/150/190/230 for the duration of this move, and he can transport back to the place where this technique was first used from the start of the ability to the end of it. It lasts for 6 seconds.

R - Lucas Rising
Kleine's body is cloaked in a deadly blue fire for the duration of this move. Added on to all of his basic attacks is something called "Holy Fire", which slows down enemies and increases damage done to them by 7%, stacking three times. Each basic attack has 15/30/40 additional damage for the duration of this ability. It lasts for 20 seconds.

He'd be an ad caster/bruiser. Obviously from his abilities he's a hardcore armor shredder.

I don't play, but I'm probably going to start soon, so this may or may not be all good or correct.

Katsu Naikiri
Melee Duelist

Passive - Katsu's unrealistic and irrational persistence lets him slip up from hell once in a while, granting him the ability to revive after being killed after 2 seconds. This only works twice per 2 minutes(starting at the first death), resetting after such time.

Q - Slash
While close range and lighter damage, this can be used repetitively much faster with a very fast attack speed compared to most other basic abilities which is useful at causing large amounts of damage over time. It also slows the target's attack speed by 5/10/15/20/25% for 5 seconds. Each cut does 10/15/20/25/30 per cut.

W - Hilt Smash
Smashing the butt of his sword's hilt into the enemy, he causes 50/100/150/200/250 damage and stuns the enemy for three seconds.

E - Thrust
With the longest reach of Katsu's attacks as well as the fastest execution, Katsu stabs his sword out at a target to cause 100/150/200/250/300 damage as well as knocking them down for three seconds(Knockback+Stun). This ignores 12/14/16/18/20% of armor.

R - Ultimate Sword Stance
Katsu uses all of his greatest techniques instead of his normal ones, increasing the effectiveness and damage of all his basic abilities by 2/2.5/3 for ten seconds. Afterwards, Katsu's body is heavily damaged with his movement speed, attack speed, and damage halved for 5 seconds.

Katsu is meant to take care of single, tougher enemies instead of mobs with a very focused-fire as a damage-dealer as well as harder to kill despite his low armor & medium health.
