Dennis is a mischievous little boy, who's main aim in life is to cause trouble. He even has a secret supply room. It looks like an advertising hoarding in the street, but if he does 'hop scotch' correctly on the pavement outside it, then it opens up into a room that has everything a naughty boy needs.

Dennis seems to wear the same clothes everyday (in the daytime), a red and black pullover, with black shorts. I think his mum must have been lazy and decided to buy a truck load of the same clothes.

Well, Dennis seems to like the look and this has means that his bedroom hasn't escaped the stripes treatment. His curtains and bed are striped and when he's in a good mood, he loves to bounce up and down on his bed.

Dennis knows when he's naughty and does know right from wrong. When he has to, he knows when to to the right thing. Such as battling against Reg Trademark, who invents stupid gadgets (like a chocolate fireguard) and he tried to brainwash everyone in Beano Town. Dennis even tried to stop Clint Catzenburger taking over his house and drilling for oil.

His main rival is Walter, who thinks he is better than Dennis, so Dennis goes out of his way to upset Walter and any plans he has. He even found out that Walter had become the leader of the Goblins to do battle with the Tooth Fairies (I kid you not). So Dennis became a spy for the tooth fairies and took Walter on.

His number 1 friend is Gnasher, his dog. They go everywhere together and when their plans go right he loves to say to Gnasher, 'Give me Three!'.

Once he was dressed as a baby (called Norman), to fool a Guest House owner into thinking that they had no pets. He was quite upset when she thought he was one of the ugliest babies she had seen. But funnily enough, Gnasher quite liked the experience or being a baby (being fed constantly).

That's not the only things he saved, he saved the the whole of Beano Town when Reg Trademark (worlds worst inventor) tried to brainwash everyone to buy his gadgets. As a dog, he was unaffected by the brainwashing sounds and instead he Gnashed the tape and freed them from Reg's spell.

Gnasher was once mistaken for a rat and the rat catcher chased him back to the country he originally came from - Abasinia. It is a small tropical island, where his mother and father live with the rest of his family.

Gnasher was delighted to see them all again and eventually they turned the tables on the rat catcher.

Walter thinks that he can beat Dennis at everything (which isn't true) and he buys anything he wants to help him to this. You see, Walter's father is rich, but this hasn't helped Walter as he has become spoilt which explains his attitude.

Walter has his own dog, but it doesn't look as mean as Gnasher and instead looks a bit girly, as it is a white Poodle called Foo Foo. But this doesn't mean that its a push over, as it loves to take on Gnasher when it gets the chance.

Walter can be quite a bitter person and can hold a grudge for years. Such as the time he became leader of the goblins and used them to attack the Tooth Fairies and claim back his baby teeth (as he thinks he wasn't paid enough for them!).

She loves it when Walter shows off and is Walter's girlfriend (not sure Walter knows this). But she can be a bit fickle, especially if someone speaks to her in a French accent. She goes all 'lovey dovey' over them and this normally makes Walter really jealous!

He speaks with a lisp and is a bit of a scaredy cat, but he is one of Dennis' closest friends and will always try to help out.

He can be a bit stupid, such as the time he sold the deeds of Dennis' house to a Texan who was after oil underneath the house. Also Pie Face owns a parrot called Polly, who is very good at doing impressions.

He meets up with Dennis and Pie Face at the Tree House to decide how they can cause mischief next.

One thing he doesn't like doing is spending too much money, he wouldn't even pay the extra to reserve a room for their holiday! So the place was fully booked when they arrived.

He isn't keen on his Aunts, who are really bossy.

Like most mothers, she thinks her little boy is an angel. When she recognises Dennis is being naughty, she shrugs it off and doesn't discipline him.

Be very careful if you see her behind the wheel of a car. Her last car was a bumper car (dodgem), so you can guess how safe she is at driving.

He spent time in India and loves telling stories about his time in the army (yawn!).

If he has a problem, then he goes back to HQ and gets the Brigadiers to help him (basically they agree to anything he says!)

Once he even baby sat Dennis. He treated it as a military operation, which is wise really, but was outsmarted by Dennis when he was conned into telling Army stories all night. So once he fell asleep, Dennis snuck out to cause chaos.

To relax, he likes to listen to a CD called 'Military Explosions', which is exactly what you think it is - bomb explosion noises (what a nutter!!). His real name is Godfrey.

He has delusions of grandeur and even set up a court with himself as the Judge. If the authorities hear about this, they'll fire him!
