Green Knight's specialties include damage over time, crowd clearing, and boss slaying.
The Green Knight's element is Poison. All poison attacks do three hits of "damage over time". However, about half of the enemies in the whole game can resist that type of damage, which makes it about as effective as Fire, and makes it a relatively effective element.
He is one of the four main King'sKnights, to whom he serves with loyalty. He will defend the kingdom at all costs, even if it means risking his own life in the process. His magical arts revolve around the use of poisoning clouds which can inflict poison status to any enemy who comes in contact with them. For this reason, he plays a more strategic role in the battlefield, as he can first poison a strong enemy and let him take damage over time, while he concentrates on attacking the rest.
Damage/Hit: Base Magic Damage x 0.5 + Poison DoT x 3
A poisonous cloud billows forth, knocking over any enemies it hits and poisons them. The poisoning damage over time effect makes this pretty powerful, and potentially superior to fire, depending on whether you want fast kills and boss slaying with Green Knight, or better crowd control as well as easier juggling with Orange Knight.
Each upgrade level adds to the range and to how many max hits the spell can inflict on an enemy that is not knocked over by it. This spell's collision is a bit odd in that it can go a decent amount past terrain obstacles such as walls, pits, and the line in the volleyball game, although it does not get its full length like Industrialist and Fencer's splash attack does.
This attack is comparable to Ninja's, however the slightly longer range and damage over time make it optimal for crowd clearing, while Ninja's is geared towards boss slaying. (Not that Green Knight is a bad boss slayer; Ninja is just a better candidate, but that's not a reason why Green Knight is bad, but why Ninja is a better choice for boss fights).

Green Knight has a different heavy attack (/) than the rest of the characters. Instead of spinning his weapon, he does a backflip in the air and attacks both sides. This feature, although unique, hinders his juggling ability meaning the player will have to come up with alternate juggle combos if they want to do well.
