Dota 2/Barathrum the Spirit Breaker

Spirit Breaker is a melee strength hero who can be played as a ganker or a semi-carry. His abilities let him overwhelm enemies through sheer speed and brute force. His Charge of Darkness is his signature ability, allowing him to chase down a target with extreme speed from anywhere on the map, going through anything in his path. His Empowering Haste is a very powerful aura that makes his team stronger at chasing down enemies and escaping. His Greater Bash directly synergises with his active abilities as well as his normal attacks, locking down heroes with powerful stunning attacks. His Nether Strike will also track his target down, knocking them back with massive damage and bashing.

Charge of Darkness
Charge of Darkness will make you charge towards your target, moving across cliffs, destroying trees in your path and stunning any enemy unit with a Greater Bash in your way. Once you reach the target, you will stun it. If the target dies before you can reach it, you will switch to the closest enemy unit near the target. While you're charging, you actually move faster than the normal move speed cap for units, which means you're the fastest thing in the game. This speed can surprise an enemy when you enter their sight range out of nowhere, and it makes it impossible to outrun you. It is an easy way to start a gank attempt, as you can target a hero from across the map and let the game autopilot you right to where that hero is. Do note that the enemy teamwill usually inform their teammates if they see you charging past them.

Nether Strike
Nether Strike makes you teleport to the target, dealing damage to it and stunning it upon teleporting. There is a short wind-up before you actually warp to the target, during which you can be interrupted by other spells. It is basically a souped-up version of Phantom Assassin's Phantom Strike. The bash and damage is great for locking down an enemy as you go for a kill. It can also be used to finish off an escaping hero.
