Dota 2/Pudge the Butcher

Pudge is a melee strength hero whose ability to gank is known and feared by a lot of players. His signature ability is Meat Hook, letting him pull an enemy from a safe spot to him, where they are in much more trouble. He can make his body Rot, damaging himself but damaging enemies more. With Flesh Heap, every kill he gets will only make him tougher, letting him achieve insanely high hp totals. Finally, his Dismember locks his target down for a mere 3 seconds, greatly damaging and even killing them.

Meat Hook
Meat Hook launches a hook at the targeted area, snagging the fist unit it touches and dragging it back, dealing damage and mini-stunning if it's an enemy. The damage it deals is pure damage, which ignores armor and magic resistance. This is arguably your best spell, so learn how to aim it properly. While catching a hero with it might sound easy, you will often have to snag one in the middle of a creep wave, one that is very mobile or one that is hidden in the fog-of-war. With it, you can hook an enemy out of nowhere to initiate a gank, after which they will likely be heavily injured or dead. You can also use it as a damage tool or to chase down enemies. Since you can also hook allies without the harmful effects, you can pull one out of danger, or even pull them to a safer place as they are channeling a spell. For instance, you can pull back an allied Enigma channeling Black Hole to put him in a safer position. The Black Hole will still be at the same spot.

Rot
Rot is a toggled spell that deals damage and slows enemies around you, but does damage to you too, though due to your high strength you won't have to worry about it as much. The self-damage can kill yourself, so you can use it to deny yourself. Rot can also be used while channeling Dismember without interrupting it, so it's good for tacking in that extra damage. Be careful of silences because you cannot toggle it off when you are silenced, which can be very bad when your health is dropping low.
 * Ability: No Target, Toggle
 * Damage Type: Magical
 * Damage: 35 / 60 / 85 / 110
 * Radius: 250
 * Slow: 20%

Flesh Heap
Flesh Heap grants you extra magic resistance, but more importantly it gives you bonus strength every time you kill an enemy hero or an enemy hero dies nearby. The best thing about this skill is that it is retroactive, meaning that it still gains charges when not learned, instantly applying its effects when you learn it. More strength means more survivability and, since you're a strength hero, more damage. If you are on a crazy killing spree, Flesh Heap can increase your momentum even more.
 * Ability: Passive
 * Magic Resistance: 4% / 8% / 12% / 16%
 * Strength Bonus: 0.9 / 1.2 / 1.5 / 1.8
 * Range: 450

Dismember
Dismember makes Pudge eat his enemy alive, dealing damage per second and stunning them. It lasts 3 seconds on heroes, 6 seconds on creeps. This is the final ability in the most common Pudge combo, which is to Meat Hook, activate Rot and pin them down with Dismember. It can also be used to initiate a kill if your enemy is close enough.
 * Ability: Channeled, Target Unit
 * Affects: Enemy Heroes
 * Damage Type: Magical
 * Damage Per Second: 75 / 125 / 175
 * Mana Cost: 100 / 130 / 170
 * Cooldown: 30
 * Scepter Strength Multiplier: 0.75

Aghanim's Scepter can be bought by Pudge and will grant bonus damage based on his strength for Dismember as well as heal him for the amount of damage that Dismember does.
