Tiny Labs is a organization tasked with keeping the peace in the Zenith Society. It was founded by Mr. Tiny.
There are three types of people at Atlantis:
Scientists wear lab coats. Agents wear suits. Guardians wear futuristic battle gear. All the uniforms change color based on the job they do.
Tiny Labs was founded when the Zenith Society emerged, originally as a "Police" of the Zenith Society it soon became more, and they started doing advanced research into TLT. Atlantis was the first base, but since many high level people in the Zenith Society were also high in the normal society HQ was founded to accommodate them. Tiny Labs grew to become one of the most powerful public organizations in the Zenith Society.
