The Mega Knight is a Legendary card in Clash Royale that is unlocked from the Electro Valley (Arena 11).
It spawns an area-damage, ground-targeting, melee, ground troop with very high hitpoints and high damage.
Upon deployment, he will deal damage to enemy units around him in a 360º area around him, and inflict knockback. If there are ground units between 3.5 and 5 tiles of him, he will stop moving and begin charging a jump attack which takes 0.9 seconds to execute, and will deal double damage, and inflict.
The Mega Knight is known for his ability to deal huge area damage, making him a powerful card in the game.
However, he has few effective counters, with the PEKKA being one of the most effective due to its damage advantage over the Mega Knight's weak splash damage
