Gray Knight's specialties include damage over time, extreme knockback, demolition, basic juggling, and combo locking.
Gray Knights are first seen drinking ale in the Barracks in the Home Castle level. A wounded Gray Knight is seen kicked from the door that leads into the Evil Wizard introduction scene. The aforementioned Knight dies, so the other Gray Knights go attempt to kill the Evil Wizard, which they fail and also die. A Gray Knight is seen fighting off against some Barbarians in the Castle Keep level.
More Gray Knights are seen in the background and in the route that the player(s) go through, many of which die attempting to kill the Barbarians in the Barbarian War level.
A couple of Gray Knights are seen fixing cannons and tents with wrenches and hammers near the King in the Tall Grass Field level. After defeating Pipistrello in the Pipistrello's Cave level, Gray Knights are seen next to the King who is on a Horse; also, they will attempt to take some Gold that the player(s) can collect.
After getting out of the cave, Gray Knights are seen assisting the player(s) in storming the castle in Flowery Field where the Green Princess is being held and they also help the player(s) fight against Bees, Killer Beekeepers, and Coneheads. Once the player(s) have entered the interior of the castle in the Wedding Crash level, the player(s) jump through the window, and Gray Knights are seen falling onto the floor, killing them instantly.
It is speculated that Gray Knights appear in the game as Skeletons in multiple levels, but are only confirmed in Wizard Castle Interior, where the Necromancer brings them back to life in a room filled with corpses, enemies and allies. Instead, the Gray Knights fight against you, not with you, when the Necromancer resurrects them in the Lava World and Marsh levels.
Gray Knights are finally seen in the Barracks again after the player(s) have successfully killed the Evil Wizard in the Final Battle level, where they again, drink alcohol but also some look at a Thief that is shooting his Bow and Arrow at an Evil Wizard poster pasted onto a target who impresses the Blue Princess and makes a Gray Knight nervous as the Thief shoots near another Gray Knight's head.
Gray Knights are absolutely loyal to the King, as they are the bulk of his army, they protect him as well, and help the player(s) in multiple levels.
Gray Knight at first, to many beginners, appears to be yet another shameless carbon copy of the dedicated and fan nicknamed "Arrow Rainers", whom are Thief, Peasant, Civilian, Open-Faced Gray Knight, and Stove Face. However, this is fortunately not the case with Gray Knight. His Magic Projectile and Air Projectile are the best in the game, alongside Conehead and Royal Guard's. Gray Knight is a key playable character to utilize Spellweaving when learned. Elemental Infusion damage is a minor component to Gray Knight's Magic due to its extremely inconsequential viability in the Level 50 Combo () besides taking longer to kill the likes of Frost King and Painter.
Arguably one of the most difficult characters in the game due to his Magic Projectile and Air Projectile.
Decent Castle Crashers. Spellweaving makes Gray Knight practically invincible in some normally key difficult levels, when mastered.
The best character in Arena, along with Royal Guard and Conehead. The difficult set up includes a mediumweight combo, and an Air Projectile. This can be customized accordingly. Downside is the fact that Gray Knight has "Arrow Rain" as his Splash Attack.
