Ninja is an enemy and also one of the 31 Playable Characters in the game Castle Crashers. His magical attacks are Non-Elemental and his starting weapon is the Sai.
Ninja's specialties include advanced boss slaying, combo locking, basic juggling and knockback crowd control.
Background
Ninja first appears in a group in a pirate ship attacking and boarding the ship that the player(s) is/are on, but fail and get their ship sunk in Pirate Ship. Ninja's final appearance is where he is resurrected by the Necromancer to fight for him in Necromancer's Room in Wizard Castle Interior.
Magic
Splash Attack
"Smoke Screen"Element: Stealth (Non-Elemental)
Max Hits: 1 per upgrade level (max 7)
Damage/Hit: Base Magic Damage x 0.5
A puff of purple smoke appears in front of you, knocking enemies over. Each upgrade adds another puff in front of the previous ones, up to a total of 7. A common misunderstanding is that this spell has much less range than most other splash attacks; however, the range is actually longer than what is shown, and can best be described as adding another puff at the end of the last visible one. The spell also triggers a special sound when used where Ninja vocally speaks with Chinese-like chimes playing afterwards. This attack is very rapidly damaging. It's actually so rapid that Ninja kills bosses faster than Red Knight, and he also has smaller hitboxes, which helps him hit slim targets like Antlions more times than normal characters would such as Fire Demon, Brute/Snakey, etc.
Because of this, even though the speed is less than that of those characters, the mechanics make it more economical because more shorter range/smaller hitboxes = hits per cast = more damage (as well as more XP) per cast = higher DPS = more effective boss slaying (as well as farming because of the XP). Long story short, sometimes less is more. Sort of like a well made guitar solo, it doesn't need to be as fast as possible as long as there's some speed and the artist puts some more thought into it. The difference is significant enough to make a visible impact on the results.
Magic Projectile
"Shuriken Toss"Element: Stealth (Non-Elemental)
Damage: Base Magic Damage
A spinning shuriken used as a magic projectile. Ninja vocally speaks when doing this, too.
Elemental Infusion
"Armor Pierce"Element: Non-Elemental
Damage: Base Magic Damage^2 + Base Melee Damage^2
Use 
/ 
to perform. This attack pierces armor, and it deals two times normal damage. That means it deals as much damage to a Barbarian or Thief on Normal Mode as it does to a Stove Face or Cult Minion on Insane Mode.
Magic Jump
"Pillar of Smoke"Element: Non-Elemental
Damage: Base Magic Damage
Jump with purple cloud effect that damages overlapped enemies. Ninja vocally speaks when doing this, too.

Trivia
- While attacking a ninja he will sometimes fall over, only for the player to find the ninja substituted himself with a log, and the real one reappears on the other side of the player, attempting to attack him. This can easily be dodged by moving around once they drop the decoy, and it can be blocked with your shield.
- The log transformation may be a reference to many ninja/martial arts-based movies, such as Kung Pow or Karate Kid, where logs are often used, symbolically or physically, to represent strength.
- The reason ninjas are on a pirate ship is perhaps a nod to the old comedic conflict about "Pirates vs. Ninjas".
- The Ninja appears to be half pirate and half ninja. His attire matches that of a ninja and his weapon is a ninja sai, while his headband dons the Jolly Roger and he uses a mug of ale for a shield.
- Ninja's white irises that appear in his portrait do not appear in game.
- This character is also known as "Ninjer," and/or Sciomancer, which means "Shadow Mage."
- Ninja is a A Rank character (A-).
- His picture on the player select screen shows him shushing the player.
- As opposed to popular belief, Ninja does not have faster melee speed.
- Ninja's arrows are Kunai.
- The Ninja's starting weapon, the Sai, gives the greatest agility boost in the game, +6 Agility. This is likely a reference to ninjas having fast and quick movements, this may also be referenced by fact that the NPC Ninjas' projectile attack flies faster than normal projectiles.
- Ninja's portrait background, player tag, and attack color is Blue (#3745AD).
- On the Xbox 360, players can dress up their Avatar as the Ninja by purchasing both the hood and tunic in the Avatar Store.
