The Animalization Ray is a weapon developed by Father. As the name implies, it transforms any (and only) KND operatives into animals. The name is a misnomer, since it is more of an infinitely-expanding bubble of yellow energy than a ray. Tommy's actions however helped Father for a later plan as revealed in Operation: I.T. because this allowed Father to become KND leader when Numbuh 362 couldn't take the stress of doing her job as leader anymore.
