Predator is a powerful melee tank. The most notable talent is Adaptive Armor as it gives you an armor buff every time you are hit, stacking up to +15 Armor. Adaptive Armor can be further upgraded with talents like Ballistic Foam and combined with Block Mastery, allowing Predator to tank even bosses and Ultralisks. Combined with the Phalanx skill and the Irradiate talent, it can give you the power you need early game to survive and kill enemies just by staying close to them.
When playing Predator in a group you are responsible for protection of more squishy teammates. Positioning and timely switching aggro of enemies from teammates to you is crucial for success.
Predator has one of the highest aggro priorities in the game, only behind Odins and Captain Smoker. It means you have to be extra careful when dealing with powerful enemies as Extremely Big Guns won't save you.
If you can't directly tank an enemy or a group of enemies, you may often kite them in circles, while damaging enemies with Corona, Irradiate, help of Crap Patrol structures and units as well as teammates when playing in the group.
You may also kite them to Captain Smoker, who who will take over tanking duties from you. Especially after you pick up the Defense Damage Artifact. But be careful - even though he's very powerful and tanky, strong enemies like ultralisks, bosses and Hive guardians deal a lot of damage to him. So you can't just let him handle everything.
Predator has low point damage, but don't underestimate his area damage from Corona and Irradiate (especially with Toxic Waste perk). Good Predator's damage score can be easily comparable with most of other heroes.
Sun God Mastery increases Corona's damage by 50, its range from 6 to 8, its beam count by 1. It also causes Predator to passively fire a single Corona beam every 5 seconds. It's even more important early in the game as Predator does more damage AND it'll be able to see cloaked units like the ravager on hellwalker, the nemesis as well.
Each stack of Weapons Research Mastery increases the damage of Corona by 10, Retribution Field by 1, and basic attacks by 2, for a total of +100 Corona, +10 Retribution Field, and +20 basic attack damage.
This mastery is important because it reduces the cooldown of Corona - it's also nice to have the other abilities' cooldown reduced.
Gives more damage to your Corona against Massive targets (40 per beam).
Adaptive Armor Mastery increases the duration of Adaptive Armor stacks from 8 seconds to 11, and causes each stack of Adaptive Armor to increase Predator's maximum hitpoints by 1%.
Block Mastery applies a passive buff causing all standard attacks to deal no more than 125 damage per hit. This gives Predator unique near-immunity to damage from bosses and Ultralisks. Block does not affect spell damage, however it does affect the attacks of the Hybrid General, allowing Predator to fight the General head-on even without the shields of an Odin. This mastery is very necessary to tank Nemesis on Hellwalker and Primals. The primals do LOTS of damage, with block mastery that damage is reduced. Very important to get when you go out alone deeper in zerg territory
Nuke Mastery increases the blast radius of Nukes from 8 to 11, gives them +600 damage against Heroic targets (including Hatcheries, Lairs, and Hives), and allows them to be fired anywhere on the map within vision. This is not always extremely useful as the increased blast radius can cause friendly fire problems, but with other Nuke talents it allows players to shred the final Hive cluster and cut off the flow of reinforcements heading across the bridge.
Unstoppable Force is Predator's Score Unlock Mastery. It increases Predator's energy regeneration, movement speed, Inspire's target count, and Corona's damage by 100, beam count, and structure damage. While it is not available in the early game when such enhancements would be most useful, it can provide useful additional pressure starting from Omegalisk area. Unstoppable force greatly reduces spell damage and make battlecry OP. It'll do wonders on the Elder Hive Guardians and with this ultimate mastery when you use demoralize and battlecry, the fellow players close to you and odins are buffed and nukes will hardly do damage anymore. Combined with Booming voice and oh boy, the area over which predator can buff is significantly increased. For example on Hellwalker, every third nukes will cause a nukeback. In a multi player game when predator has booming voice and unstoppable force, the nukebacks will hardly do damage and anvil can nuke freely. In addition, the fireballs from a ravager are laughable and so are those of brutas. The predator can just tank them with demoralize and battlecry on autocast. PLEASE make sure you've cat lightweight complete so it casts much more quick. Even if a player next to you take a fireball full on the head, no problem, he's buffed. :) Combined with Armor and Block mastery, a predator with battlecry and demoralize on autocast can simply tank a Yagdra and kill it.

Significant Talents and Explanation
Compound plates are very important for the predator. You can learn compound plates 3 times. With only one time compound plates you remain somewhat squishy. So you need to have this talent at least twice to be able to sustain more damage. I quote: "Adaptive Armor grants you additional armor per stack". The question that remains are these: 1) how much additional armor per stack? 2) how much is a stack? Without these answers it remains very vague. The other very important talent I always want it Adaptive Shields, it states: "Adaptive Armor grants +1 shield armor per stack". Question again: how much is a stack? Ballistic Foam is another notable one: "Each stack of adaptive Armor grants a small bonus to life regeneration". Question: how much is a stack of adaptive armor?
The questions are addressed below in an answer from Thenarden:
Adaptive armor is a buff that can stack on the hero, meaning multiple "versions" or instances of the buff at the same time. And each of these instances keeps its own duration (8 sec). This means that the first time your hero gets hit, he gets the buff with 8 second duration (1st stack). After this 8 seconds, the buff would disappear. BUT: If you get hit again in this time, a counter is increased (now 2 stacks). 8 secs after the first hit, the counter is decreased. And 8 seconds after the second hit, the buff is removed.
The default maximum stack count for adaptive armor is 15 (and I don't know wether that is changed somewhere somehow)
So if you get hit 15x in a period of 8secs, you have 15 stacks of adaptive armor. Same rules from above applying; 8sec after first hit, the counter is decreased.(edited)
So much for how stacks work. Each instance of the buff has certain effects. The base (not upgraded by talents) effect is a Life Armor Bonus of 1. So each time you get hit, you have 1 bonus armor for 8 seconds, up to 15 bonus. Each Compound plates talent you learn increases this bonus by 1. So with 1x Compound plates, you get +2 bonus armor per buff instance (=stack) up to +30 bonus, with 2x Compound plates you get +3 up to +45 and so on. Adaptive Shields grants a similar bonus on shield armor. So again, each buff instance gives +1 shield armor, up to +15 and with Ballistic Foam, you get a life regeneration bonus per talent and buff instance on your hero (can't give exact value, since I don't know how "Vial Regeneration Bonus Scaled" actually works).
