Defernull! Tenna vs. The Light World (deltarune/defernull)

This is Tenna from deltarune, a darkner who was accidentally brought to the real world. In the defernull universe, however, he has some changes from canon Tenna.

Defernull Tenna is a tall anthropomorphic TV-like Darkner. His head is a light purple/lilac cuboid television with two antennas with rounded ends. Tenna's face is a white screen with no eyes, a long white nose, and often sports a wide grin that can have normal blocky teeth, or sharp teeth. He wears a full black jacket and pants with white heeled shoes, a black belt with a white buckle, and a red tie as well as a thin tail with a 2-prong plug on the end of it. Under his coat he wears a white shirt with black stripes. His body under his clothes is metal with a red and green wire around his biceps. He is well built for a robotic darkner, having large pecs and a bit of a gut. He also carries a big cigar with him at all times. Tenna's Light World form USUALLY is a cathode-ray tube television with a set of antennas on top. It is implied the screen has burn-in. The TV sits on top of a red furniture pad, which is used as a buffer for a single-drawer stand beneath it.

Tenna embodies the archetypical TV host: he is energetic and enthusiastic, and always has a quick quip.[13][14] Exuberant and cartoony, he makes theatrical gestures and exaggerated movements. Tenna's dialogue is sometimes accompanied by detailed text graphics and sound effects. His humor tends to be gleefully absurd, and he often drops bizarre, wacky remarks.[15][16] Tenna is a natural charmer, consistently working to keep things fun and light-hearted for his audience.

Tenna's desire to entertain is not limited to Lightners. He expressed relief and satisfaction when King and Lancer laughed at his accidental slapstick fall, despite his initial dismay.

As an old CRT, Tenna is behind the times. He does not know much about emails, believes digital currency is secure, and considers the retro-style game The Legend of Tenna as "state-of-the-art" and "modern". Owing to his age, Tenna frequently insists on his relevance.

Tenna is nostalgic about the past, frequently talking about his memories with the Dreemurr and Holiday families.

Tenna's jubilant demeanor belies a deep-seated fear of being abandoned by the Lightners and a desperate need for their attention. He is insecure about becoming outdated enough to be thrown away or ignored. Driven by these fears, he has made at least two deals that harmed others. He convinced his ex-partner Spamton to sign a contract despite knowing it would cause serious problems. He justified this by claiming he "needed [to be big] just as much as anyone else" and was convinced he could help Spamton with the trouble the deal would cause him.[ Before Kris and Susie entered TV World, and when he was left dusty and mostly unwatched, Tenna made a deal with the Knight to hold certain Lightners — including two of his previous owners — captive, keeping Toriel asleep and trapping others in a never-ending gameshow. However, he expresses remorse for imprisoning Toriel. Tenna engages in deceptive business practices. The "BRAND NEW FAMILY CAR" he promised as a potential prize is actually an ICE-E van marked "COMMERCIAL USE ONLY!!", which cannot be legally used for personal or family purposes. He kept this prize for himself, claiming the party was not going to win it and that he was "just giving it a daily TEST DRIVE"

Defernull Tenna is a little different from this. The Defernull universe is a lot more "edgy" and "dark" than his canon counterpart. Also he can change his size at will. His normal height is around 15 feet tall.
