Tony is a teacher very devoted to time, often growing aggressive if someone questions him and his intelligence of the topic. To strangers, he can come off as obsessed with time, rigid, and generally dislikable. Although, to the people he enjoys being with, He grows softer, gentler and kinder, especially with his romantic interests. He is a wall clock with a navy-blue face, two scarlet red arrows (possibly in the style of a moustache) and four yellow marks resembling the lines clocks usually adorn. His facial rim, arms, and legs are a darker shade of blue. He wears a yellow bowtie with red stripes, white gloves, and yellow and red shoes. He also has very long, slim legs and arms. He can make very loud beeping noises.

Colin is a teacher who enjoys technology, considering he's a computer. He's somewhat likable for his ability to operate like a house computer, give information, etc. although, he can be quite interruptive, and slightly arrogant. Much like Tony, he's only more kind to the people he enjoys being with, and can be quite friendly. He dislikes physical contact unless it's by a romantic interest, especially with his keyboard. And even with a romantic interest, he can still come off as nervous even if they've been doing It for years. He is chunky, rectangular and beige-colored like an old-fashioned personal computer. His head is a monitor, with square eyes side-by-side with a rectangular mouth beneath a large display screen for a forehead. He is mostly based on old 1990s and early 2000s computers. If he were a humanoid, his "cranium" by analogy would be proportionately very large, representing his high intelligence. Despite this, there is a door in his forehead that opens to reveal that his "digital mind" is surprisingly compact and apparently a mixture of wires, shiny stones and fleshy organic material. He speaks with a glitchy, synthetic computer voice and slightly awkward, unnatural intonation that sounds like early speech synthesizers. He demonstrates a very large vocal range that tops out with unpleasant high-pitched screeching. When standing upright, Colin's keyboard goes vertical and becomes his torso, and his arms and legs are black cables. He has a computer mouse for each foot. Otherwise he perches on a stand and lays out his keyboard and mice on a desk or table like a regular desktop. His hands look like mouse pointer icons that can change appearance at will, e.g. to change into an arrow, or an hourglass. His keyboard has several rows of keys that are able to change color between red, yellow, blue and even green, despite green not being deemed a creative color. His teeth make a quiet, keyboard-like clacking sound whenever he speaks.
