I have written this before in a different topic, but I think it was out of place so I decided to copy it down in this thread.
Zlythax. (Poison/Dark)
I thought it was a cool name, it's design sorta looks like a cross between the creature 'venom' from spiderman, and sableye. This creature has a long, furry tongue that hangs out from it's Sableye - like grin. It has blank, soulless blue eyes (like Sylveon), and has long, black scythes that replace it's hands (like Kabutops's blades - except longer and black).
Now it's stats:
Ability: Assassin (Increases the accuracy of OHKO moves, like guillotine, from 30% to 80%)
Hp: 100
Atk: 15
Def: 80
SpAtk: 15
SpDef: 80
Spd: 150
Base stat total: 440
You are probably disappointed with it's attack stats, but when it has the ability 'Assassin', who needs attack? Zlythax can learn ALL the OHKO moves, including a new one called 'Death Slice', a dark type guillotine which is it's signature move.
Since Zlythax has a stunning 150 speed stat, it should OHKO everything in it's path, at least 80% of the time!
