How to unlock the Kingslayer achievement in XCOM 2 - Definitive Guide
If you enable the story missions to get the rulers to appear you need to complete the mission 'into the nest'. After that all 3 will appear in other missions over time (and you encounter the Viper King in the mission). If you don't activate this dlc they will appear in your missions as one of the pods randomly. (not in story missions with fixed pods).
Don't panic if they run away on your first encounter, you will keep encountering the same ruler until it no longer runs away once you have done enough damage to them.
Bear in mind that you need to be extremely prepared for these in terms of playstyle they work quite differently. Whilst they are present on the field they get 1 move between every 1 of your soldiers moves so moving is not recommend if you can avoid it as the Ruler will get another chance to hurt your soliders in that time. This occurs irrespective of normal enemy turns. You can use this to your advantage. If you work out where one is on the map, you can set all but one of your soliders in overwatch and get the 5th one to trigger it to come into range and all your soldiers will take an overwatch shot but it will count as 1 action.
WotC UPDATE:
If you choose the Integrate DLC option the Rulers will not appear until they are guarding facilities (it will say something like a dangerous alien is guarding this facility) after that they will roam future missions. With this DLC they also receive a significant nerf undoubtedly making the achievement quite a bit easier.

Kill all three Alien Rulers, I found that the rulers only react to units in it's LOS so you can get a bunch of damage onto it with Overwatch shots from soldier that were out of LOS at the time of setting to OW, but be aware it will react to OW if your unit is in LOS when setting OW.
Also, another thing is that they don't move on the standard alien turn, so if they are the only enemy in range, ending your turn early to prevent reactions sometimes is handy.

Kill the Viper King (Viper Vanquisher), Berserker Queen (Berserker Breaker) and Archon King (Archon Annihilator) to obtain this trophy. You do not have to kill them the first time you encounter them. If they escape from battle, they will continue to show up in later missions until they are killed. Any damage done to them carries over to the next mission.

Attention! The trophy is easy to miss.
Rulers can be found at secret bases, the purpose of the missions is to blow up the bases; after the destruction of the bases, the progress of the Avatar project decreases.
The pre-mission briefing will state that "the facility is guarded by a powerful alien."
When damage is inflicted to half the Ruler's health bar, he will try to escape from the battle. They do this with lightning speed, opening a portal near themselves and jumping into it within 1 turn. The difficulty is that the Rulers have a lot of health and respond with their own move to the move of each of your fighters. Therefore, it is necessary to think through tactics in advance, arrange the fighters and for some of them select the “observation” mode. It is also a good tactic to place a ranger/templar with the “meat grinder” ability near the portal into which the Ruler will head. Thus, the Ruler running in the next cell will receive a blow from the sword.
Killed two rulers (one at ~45% of the game, the other ~65%, the third could not be found. Once, entering the interface of the mission to destroy the object, Avatar saw an inscription that there was a “powerful alien” at the object, but left from the mission to set up and equip the fighters, after which during the second briefing and completion of the mission the alien was no longer there!!!
I found the third ruler again with ~95% progress.
Therefore, it is necessary to immediately begin the mission if you are on the trail of the Ruler.
