History ComicStrip / DennisTheMenaceUK

* LighterAndSofter: The new series makes Dennis much more goody-goody. He's still a menace, but he has been softened up a lot. This could be a reflection of the fact the modern Dennis is raised by the strips original Dennis, with whom Dennis Jr. has a better relationship, than Dennis Sr. had with his dad.

* DenserAndWackier: The original comic was never grounded in reality, but the 1990s series takes it UpToEleven. The series feature aliens, mad scientists, sentient socks and other wackiness.

* MoreDakka: In one episode of TheNineties cartoon, Dennis and Gnasher got a pair of HumongousMecha which happened to look like them; Gnasher's had an enormous gun pop out of its "nose". Then more guns. Then some [[UpToEleven more]]. Then some '''''[[SerialEscalation more]]'''''. [[spoiler:[[DeconstructedTrope Then it fell over]].]]

** Walter to varying degrees: his parents seem to be rich enough to buy him whatever he wants whenever he wants it in the 2009 and 2013 series, but it's taken UpToEleven in ''Unleashed'' where his dad is the mayor of Beanotown and he's able to boss any adult around.

* GettingSickDeliberately: The 1990s series episode "Couldn't Catch a Cold" has Dennis try this, but fail. He wants to catch a cold so he can stay home from school, first trying to catch it from his father, then (after remembering his grandma claim that colds can be caught from being cold or wet) by walking in the rain in summer clothes, swimming, and sleeping with fans on. None of these attempts work, and when he does catch a cold (likely from his father), [[ShaggyDogStory the school had planned a beach trip]].

This Dennis has no known surname and is slightly older than the [[ComicStrip/DennisTheMenaceUS Dennis from across the Atlantic]], 10 years old rather than 6 (though at times he has been portrayed as slightly older again). He also has dark spiky hair and an iconic black-and-red horizontal-striped jumper, and he is joined by his similarly drawn spiky-haired dog, Gnasher. He truly revels in doing naughty or mischievous things and is at odds with his parents, the local police, his neighbours and the "softies" of his neighbourhood.

** The 1996 TV series switched from traditional cel animation to digital ink-and-paint for its' second series. The colour scheme also became brighter and less washed-out.

* ElvisImpersonator: Butch Butcher. Made more blatant in the 2013 where he even does the voice.

* ThePigpen: Getting dirty is one of Dennis's secondary traits. In one episode of the animated series, he shown to have an uncontrollable compulsion to get dirty. When his father threatens him with grounding if he gets messy before his school photo is taken, Gnasher has to keep dragging him away from messy situations.

* PokemonSpeak: Gnasher says his own name in place of barking in the 2009 television series, though his other dog noises are normal.

* OutnumberedSibling: Gnipper has five sisters - Gnatasha, Gnaomi, Gnanette, Gnorah and Gnancy.

** Pie-Face as of September 2017, as his design was completely changed to match the new ''WesternAnimation/DennisAndGnasherUnleashed'' series. Curly got it even worse - he's {{PutOnABus}}.

* Non-Nude Bathing: Unsurprising considering the age audience, but in the TV series episode "Bathnight Club", he is put into the bath with swimming trunks on.

* SpecialGuest: The nineties series featured guest appearances from the likes of Creator/HughLaurie, Creator/BillyConnolly, Creator/LesliePhillips, Creator/WillieRushton and his ''Radio/ImSorryIHaventAClue'' co-star Tim-Brooke Taylor, Creator/BernardCribbins, Creator/KenDodd and Creator/BrianBlessed.

** One episode (maybe in one of the 1970s Annuals) revealed that Dennis's Dad was exactly the same as Dennis when he was younger.

* EarlyInstallmentWeirdness: In his first ever strip he was wearing a ''necktie''. Apparently by choice. Seriously.

* GenderEqualEnsemble: The main ensemble of Dennis and his pals count as of the modern Beano comics if you don't count Gnasher or Pieface's pet potato Paul.

** JJ in ''Dennis and Gnasher: Unleashed'' is also shown to have a case of those. Probably justified on how athletic she is.

* YouthfulFreckles: Dennis is shown to have those in Unleashed

* CanonWelding: One issue of the comic implies Dennis' father in 2009 cartoon is the original Dennis, and that the new Dennis is actually Dennis Jr: There's a flashback to his childhood showing him as Dennis the Menace. Also the original Dennis and the new Dennis have subtly different designs; specifically the order of the red and black hoops on their jerseys are opposite - old Dennis wore black-red-black-red from the collar down, Dennis Jr wears red-black-red-black from the collar down.

* StealthSequel: One issue of the comic implies Dennis' father in 2009 cartoon is the original Dennis, and that the new Dennis is actually Dennis Jr: There's a flashback to his childhood showing him as Dennis the Menace. Also the original Dennis and the new Dennis have subtly different designs; specifically the order of the red and black hoops on their jerseys are opposite - old Dennis wore black-red-black-red from the collar down, Dennis Jr wears red-black-red-black from the collar down.

* Four-TemperamentEnsemble: In ''Dennis & Gnasher: Unleashed!'',this applies to Dennis and his pals(the four main characters).
