He appears just like his Clash of Clans counterpart; a man with brown eyebrows, beard and a mohawk, a golden body piercing in his left ear, riding a pig.
With his high amount of damage, the Hog Rider can be placed with a high hitpoint card, such as the Giant, to distract enemy troops or with support units such as Goblins, dealing lots of damage. However, you can counter this combo with the Skeleton Army, Barbarians, or a Minion Horde.
Note that due to the fact that Giants and other tanks occupy a lot of space in the Arena, you may have problems with the Hog Rider getting to the Crown Tower due to the large troop blocking the Tower in front of him.
The Hog Rider in conjunction with the Freeze can be extremely effective. Firstly, the Hog Rider is spawned, and if the opponent spawns troops to defend the Tower, cast the Freeze. As the Freeze freezes the defending troops & Crown Tower, and the Hog Rider will remain unhindered to attack the enemy's Tower. It is also recommended to drop cheap ranged troops or Goblins to go with the hog in order to deal additional tower damage and lighten the counterattack that will support the frozen troops.
The Hog Rider only attacks buildings. This means that it can easily be distracted by building cards, but he can also help out by destroying them. A Cannon is a good counter as it can pull the Hog Rider away, distracting it and giving the towers ample time to damage or kill him. Tombstone is also effective as the spawned skeletons can damage the Hog, but can often be more easily countered.
A Tornado placed in front of your King's Tower when a Hog Rider is approaching one of the Crown Towers can activate your King's Tower, helping you in defense.
He can also clear a key defense or front-placed Elixir Collector for a future push.
If the opponent places an Elixir Collector far back in the middle in front of the King's Tower, the hog can be deployed on the river, and he will jump the river and go straight for it. However, it is important to keep in mind that this placement puts him in the kill zone, where both Arena Towers can target him.
A very powerful combo is the Hog Rider, the Musketeer, and the Valkyrie. The Musketeer is for dealing damage, the Valkyrie is for protecting the Musketeer and Hog Rider from mass troops (i.e. Skeleton Army, Spear Goblins), and the Hog Rider is used to tank for the Musketeer and Valkyrie.
This combination of troops is dubbed the Trifecta by the community.
This can be effectively countered by Lightning, killing the Musketeer and severely damaging both the Valkyrie and Hog Rider. Minion Horde is also effective, but the enemy can Zap them and the Musketeer will one shot them all. Even if the Musketeer is killed, the Hog Rider and Valkyrie will have enough time to severely damage the Tower.
Both Goblins and Fire Spirits can compliment the Hog Rider's very fast move speed. Melee Goblins and Fire Spirits can be devastating since they offer high damage, but are however susceptible to splash that can hit the Hog and supporting units at the same time. The Ice Spirit is also devastating since it can freeze the Arena Tower, but is does not offer as much damage. Spear Goblins are also great since they are ranged and chip away from a safe distance when facing splash units, and hence they're less vulnerable to splash units.
If a Goblin Barrel is deployed directly before the Hog Rider, they will distract the Crown Tower while the Hog Rider deals damage. This can also be useful in the reverse. The Hog Rider can act as a tank for the Goblins so that the Goblins can deal great damage.
Sending out a Miner right before the Hog Rider is sent can be an effective combo. As the tower is distracted by the Miner, the Hog Rider can deal extra damage.
Pairing the Hog Rider with the Balloon can deal devastating damage. If executed properly, the Hog Rider will act as a tank while the Balloon deals damage, and the Hog Rider can also destroy any buildings attempting to slow down the combo. Remember that this combo is very vulnerable to the Minion Horde, as neither of the troops target anything but buildings. Plus, it is easy to separate, since the Hog is very fast and the Balloon quite slow.
When he is deployed, he yells "Hog Rider!" similar to how the Clash of Clans Hog Rider does in the commercial.
The Hog Rider is based on its identical counterpart in Clash of Clans, given that both of them can jump over obstacles that normal ground units are unable to.
Although in the description of the Hog Rider the middle separating area is referred to as a "river", in Bone Pit and Builder's Workshop there is no water in the separating area.
When he is jumping over the river, he cannot be targeted by any troops or buildings. However, if he was already targeted by an Inferno Tower or Inferno Dragon, he would receive damage when he jumps over the river.
Alike Clash of Clans, the Hog Rider wears a gold earring on his left ear.
Two Hog Rider statues can be seen in Hog Mountain(Arena 10) behind the enemy's King's Tower, which explains the name change of this Arena.
When jumping over the river, the Hog Rider can jump over The Log. This also means that defenses that only attack ground will have to retarget if the Hog Rider jumps over the river.
