Krabs can also use their long scythe-like legs as their third weapon which can cause instant devirtualization. This has never happened on Lyoko either. However, when they were materialized in the real world in the episode "A Bad Turn," the Krabs used their legs to pin their victims to the ground. In the same episode, Ulrich was almost killed when a Krab nearly decapitated him, but was saved by an uncanny Tower Deactivation. Krabs usually travel and co-operate in groups of two to three, but are able to defend themselves alone. Because they are frequently used by X.A.N.A., Krabs are often defeated fairly easily by the Lyoko Warriors.
- Prior to Evolution, Krabs were only shown in sectors 1-4. It was not until the pilot of season 5, XANA 2.0, that they were finally shown in Sector 5, becoming one of only a few monsters shown in this area. This same distinction applies to the Megatanks.
