Reinhardt

A very wide barrier with high durability

Reinhardt's barrier is very wide and has a durability of 1500 HP. Also, since it can be deployed at any time, he can flexibly take space while moving.

Fire Strike, which shaves off half the enemy's HP in one hit

Fire Strike deals 125 damage in one hit, so against 250-HP heroes it can deal half their health in damage. Also, since it pierces barriers, it's easy to land on enemies who let their guard down behind a barrier.

Use heroes with crowd control

Reinhardt has a very wide hitbox and is defenseless during Charge, making him weak to crowd control abilities. Picking heroes with CC abilities, such as Ana, Mizuki, or Orisa, makes him easy to counter.

Use heroes that can fly into the air.

Reinhardt is specialized for ground combat, so he can't do anything against aerial heroes. Using heroes with abilities to fly through the air makes it harder to take damage from Reinhardt.

Use heroes that can break Reinhardt's barrier.

Reinhardt's barrier gradually recovers HP if he stows it for 2 seconds after deploying, but if the barrier breaks, he can't deploy the barrier for 5 seconds. Without his barrier, Reinhardt struggles to play forward, so using heroes that can break his barrier makes it easier to gain an advantage.

Reinhardt's primary fire can widen its hit range by swinging the camera sharply to the side.

250-HP opponents can be killed with 2 hits of Fire Strike, and 225-HP opponents with one primary fire hit plus one Fire Strike.
