Lawgivers

Lawgiver 1 

The First Lawgiver enforced the will of  when other measures, such as absorption, failed. Dressed in drab-colored robes, he carried a staff that could absorb and kill.

Lawgiver 2 

The Second Lawgiver accompanied another lawgiver, taking orders from Landru. When Kirk disabled the computer Landru, he became confused. ()

Passersby 1 
These passersby viewed the  landing party after they beamed down to the surface of Beta III.

The following day they were instructed by Landru to attack the Enterprise landing party. They were eventually stunned by Kirk and his crewmates. ()

Rioter 

This rioter took part in the Festival, a period of debauchery and lawlessness. He jumped from a street into a window, consequently breaking it, and, after staggering out onto the street again, he flung his arms in the air, screaming "Festival! Festival!" before hurrying away. ()

Passersby 2 
These passersby were on the street during the visit of the  in 2380. ()

Representatives 
These four representatives were lectured by Captain Carol Freeman on how bad Landru was in 2380.

The first Betan man, who held a pitchfork, explained that Landru was "very persuasive". 

The lawgiver agreed with the first Betan's sentiments. 

After Freeman and Ransom beamed away, the second Betan man, who had just bought a new scythe, confessed that he liked "purging people during the red hour," and that he was "going to keep doing it".  

Upon hearing the second man's confession, the Betan female responded, "Dude, there is no more red hour, okay?" and to "Let it go." ()
