File:Blok's Freeze Beam.png
The Freeze Ray is one of the weapons employed by Bloks. If a Lyoko Warrior is struck by it, he/she will be encased in ice, but not necessarily entirely, and loses 50 life points.

There are two ways the ray may be fired; where the victim is covered completely (Ulrich in Killer Music) or just the victim's limbs to insure they cannot run away, (Aelita in Distant Memory).

Sometimes members of Team Lyoko were struck by this and devirtualized only because they had only 50 Life points or less. The freeze ray has been known to accidentally freeze other monsters.
