Karroch the Beastmaster is a melee strength hero whose versatility allows him to take on multiple roles. His hawks provide free flying vision and his boars can harass, slow, and stack jungle camps. His ultimate, Primal Roar, is the longest lasting single reliablestun in the game, except Morphling's Adaptive Strike at level 4 with more strength than agility.
He is an effective support with good disabling ability in team fights . His strengths lie primarily in the slow debuff his Boar inflicts and ability to easily provide vision at crucial locations on the map. Though he is able to easily take down undefended targets in the early game,most of his abilities do not directly combo with each other, although the debiliating effects he brings to a fight can greatly assist allies (along with his passive attack speed boost aura)

Strygwyr the Bloodseeker is a melee agility hero imbued with dreadful powers to fuel violence and rip enemies apart in the heat of close combat.
He can drive targets into a maddened Bloodrage, increasing the damage of their attacks, and allowing them to heal their wounds by killing their enemies. He can also cast Bloodrage on himself turning him into a nuker. His speed is unmatched when he senses the blood of the dying, and from this perception none can escape. By using Blood Rite, he can create a ritual field where his foes will be silenced and damaged in the process. His ultimate, Rupture, sunders the skin of his victims, causing them to trail their life force behind if they dare to flee.

Bradwarden the Centaur Warrunner is a melee strength hero whose natural place in combat is right in the center of battle. His abilities stop enemies around him in their tracks and inflict heavy damage, making him an excellent initiator. He is also a powerful tank, having the highest strength gain in the game.
Bradwarden has immense natural health, and his skills' area of effect mean that he can charge into combat and incapacitate groups of enemies at a time. Hoof Stomp and Double Edge make a great combo of stunning and burst damage on short cooldowns and his Return means instant retaliation on enemies who try attack him. His ultimate, Stampede effectively turns the entire team into initiators, granting them high speed and the ability to flatten enemies under as they pass over them.
Although he is usually not played as a carry, he can scale powerfully with items, becoming a hard-hitting semi-carry that is nearly impossible to kill.

Disruptor the Stormcrafter is a ranged intelligence Hero who requires good positioning to use his abilities effectively. His signature ability is Kinetic Field, a pseudo-disable that traps enemies within a small area for a long duration. Combined with his Static Storm, Disruptor can act as the initiator for a teamfight, or supplement his teammates' initiation very well. Glimpse is another powerful spell that forces enemies to watch their movements, as Disruptor can easily drag them back to a previous location to be focused down. Thunder Strike provides Disruptor with some reliable single-target damage, but more importantly grants vision on the target to prevent jukes and escapes.

Crixalis the Sand King is a melee strength hero with one of the highest area of effect damage outputs in the entire game. All four of his abilities can affect multiple enemy units, and can combo quite well with each other. He is one of the most versatile Heroes in the game as he can push, initiate, support, gank, and even semi-carry if he does well. Late game his effectiveness diminishes as none of his abilities scale, but he can still function to support carries with Burrowstrike and Epicenter's slow. He is also versatile enough to be able to go to any lane with at least moderate success. He works well as a participant in a dual lane or trilane, but can also solo very effectively against melee enemies as Caustic Finale discourages enemies from approaching the creeps. His main role in the team is to deliver a devastating initiation, delivering both stuns and slows to the enemy team. Crixalis is also very effective at escaping and dodging with two low cost, low cooldown abilities that disjoint projectiles and can escape enemy damage. Burrowstrike allows him to tunnel underground and resurface in a short line, dealing damage and stunning all targets it hits. Sand Storm is used as escape mechanism and to do area of effect damage. Caustic Finale serves as a strong harassing tool against enemy melee heroes or as a followup after he Burrowstrikes a creep wave, allowing him to farm quite effectively. Finally, his ultimate, after a short channeling time, delivers a vast amount of area of effect damage and slow centered around himself which necessitates a safe way to channel the ability like the purchase of a Blink Dagger.

Sven the Rogue Knight is a versatile melee strength Hero with superior physical power yet is coupled with various abilities that provide various utility. He can fulfill various roles, but is often played as a semi-carry due to his high utility even without items. He possesses a versatile arsenal, from shouts that grant armor both for escaping and pushing to throwable gauntlets that disorient enemies around the target unit. With enough items, Sven has the potential to be a strong late-game carry due to his ultimate which increases his damage and his passive which allows him to hit multiple targets at once. He is a formidable foe and his versatility makes the Rogue Knight a great asset to any team.

Boush the Tinker is a ranged intelligence hero who relies heavily on his assortment of nukes for ganking and pushing. While he does have rather low stat gain, he is able to reset the cooldown on his abilities, which in conjunction with Boots of Travel gives Tinker global mobility rivaled only by Nature's Prophet, which combined with his two high damage nukes, Laser & Heat-Seeking Missile make him a constant threat. Tinker abilities' mana costs are very high, however thanks to his ultimate Rearm, and Boots of Travel, Tinker can simply to go back to base to refill health and mana, Rearm and go back to the lane to push or gank once more. Acquiring said boots early with a level advantage is key to success, considering he is lackluster without them. With the right items, mana management, and ability management, there is little that stands in the way of this hero.

Skitskurr the Weaver is a ranged agility hero, renowned for being one of the hardest heroes in the game to properly lock down and kill, despite his extreme frailty. This is mainly due to his low-cooldown Shukuchi ability, which provides him both max movespeed and invisiblity when it is used, making him highly effective at chasing enemies as well as escaping from battle. In addition, his ultimate, Time Lapse, is yet another survival tool, allowing him to regain his position and all the health he lost from 5 seconds prior. His exceptional ability to maneuver around the battle, seeking the most fragile enemy heroes, is bolstered by his last two abilities. The Swarm is a wave of insects that Weaver projects in front of him that latch onto enemies. Until they are killed off, they will gradually inflict damage over time, reduce enemy armor, and perhaps most importantly, provide vision to Weaver. Finally, Geminate Attack allows Weaver to launch an additional attack every few seconds, making his offensive all the more potent. Not a hero capable of standing on the front lines, Weaver is nonetheless a huge threat against a team that has little ability to prevent his extreme maneuverability.
