“Welcome to the future!”—General Cryptor in "The Art of the Silent Fist"
General Cryptor is the lethal general of the Nindroid Army. He is far more advanced than the other Nindroids in combat, emotions, and smarts, and is well prepared for battle, having armor and two katanas on him at all times. Like all other Nindroids, he is also capable of cloaking, although he can also shoot lasers out of his armor, which are stronger than the ones fired out of regular Nindroid's eyes.
He first appeared in "The Art of the Silent Fist", after being created by P.I.X.A.L.. He then lead the Nindroid's first attack on the ninja. After the Ninja attempted to escape in their hacked vehicles, General Cryptor used his Destructoid, and single handedley destroyed the NinjaCopter, the Kai Fighter, the Thunder Raider, and Cole's Mech. Unfortunately for Cryptor, the Ninja put the vehicles on autopilot, and Cryptor had to report to an outraged Overlord, who called him and his army a failure.
Cryptor is next seen guarding the tower where the power source was. He quickly found the Ninja after Min-Droid gave them away, and also assaulted P.I.X.A.L. when she tried to help. Zane left the ninja to help P.I.X.A.L, and plows through the Nindroids, then sees Cryptor holding up P.I.X.A.L.. He catches Zane's Techno Blade, calls him a "tin can with feelings", and throws Zane, disposing of his Techno Blade. Zane attacks Cryptor, knocking away his katanas, but Cryptor makes a comeback, then cloaks himself and pummels Zane. However, before he could finish him, the power is destroyed by Kai, Cole, and Jay, which powers down all machines in New Ninjago City, including Cryptor and P.I.X.A.L..
Later in "Blackout", he was brought back by Pythor P. Chumsworth by Electric Eels. He battled Zane and P.I.X.A.L., along with the others, while he remarked that Zane "needed a little girl to help him fight."
In "The Curse of the Golden Master" Cryptor and other Electro Cobrai powered Nindroids went to Serpentines' underground tomb to destroy ninjas. He kicks Skales Jr. and laughs to him but Kai kicks him saying that he is about to be history. Then all ninjas attack him but he just punches them. He throws Cole to Zane, Kai and Jay. After that more Nindroids come and then ninjas find out Electrocobrai are powering them so he leaves the place.
In "Enter the Digiverse" he leads Nindroids to the Borg Tower driving on Destructoid. After Borg puts up iron walls around the building to stop them of going inside, he uses saws from his vehicle to destroy them.
In "Codename: Arcturus" he asks Pythor about the Overlord's whereabout, as he suspects Pythor may be tricking the Nindroids into believing the Overlord is still alive, just to manipulate them.
Cryptor captains the Arcturus in "The Void". When the Nindroids find out that the Ninjas have entered Arcturus, he sends Min-Droid and other Nindroids to get rid of them. Later, when the Nindroids find the Golden Weapons, Cryptor warns them to not touch them directly, and a Nindroid who does so gets disintegrated. Cryptor leads a convoy carrying the Golden Weapons, but the ninjas pursue them and steal Cryptor's ignition key for the Arcturus, so that they cannot leave the comet with the Golden Weapons and take them to the Overlord. However, alien bugs eat the Arcturus and upon seeing this, Cryptor and the other surviving Nindroids use their built-in boosters to fly off the comet with their golden prize.
In "The Titanium Ninja" Cryptor faces Nya, who tricks him into repeating his low opinion about Min-Droid with the little nindroid nearby. Min-Droid fights Cryptor and both are destroyed in mid-fight when Zane freezes New Ninjago City in his fight against the Overlord and both Nindroids shatter.
- His name appears to be based off a type of Trojan Horse (Computer virus), known as Gen-Cryptor.
- LEGO intended to include him in 70724 NinjaCopter, but, for unknown reasons, decided not to.[source?]
- He is known to criticize his own army, nick naming a small Nindroid a "Min-Droid" is an example of it.
- He is the servant of the Digital Overlord.
- Pictures of General Cryptor were the first pictures of Ninjago's early 2014 wave.
