Charles is the oldest brother. He is the thinker and planner of the three, and considers himself the most responsible by far. He has a high level of intelligence mixed with a fascination for the bizarre and a love of things that go BOOM! This has led to him becoming a master of ingenious inventions, each of which he gives it's own special name.
He carries a backpack full of handy gadgets on missions. Amazingly, he can whip up a widget that suits the job at hand in a flash, using just what's around him.
Henry is the middle Skinner brother. He's the most laid back of the three boys... so laid back that he can sleep through almost anything. He's a pretty cool customer, but a cool head is often what's needed in extreme situations.
Unsuspecting villains are often fooled by Henry's laid-back attitude but don't cross him – he's fast and deadly – executing amazing physical manoeuvres that he makes up on the spot. And they sometimes work. Despite being a lean, mean fighting machine, Henry is a kind, sensitive kid.
Edward is the youngest Skinner brother. He's the class clown, quick to crack an inappropriate joke. He is the show's main comic relief as this goofy kid always mixes fun with his duties. When it comes to action Edward is more than a little gung-ho. His philosophy is that if he can see it or touch it... then he can always bash it with a really big stick. While his methods are hit and miss, Edward is a valuable team member. You never know when one of his crazy stunts will save the day.
Feisty Cousin Tara is the fourth Guardian of the Lost Secrets. Tara joins in all missions and has rescued them more than once with her fast thinking. She's younger than Charles and older than Henry and Edward, but is certainly capable of holding her own against all of them. With her mystic powers, Tara is able to alert them to disturbances in the world's balance associated with meddling with the artifacts. As with all mystics, Tara has visions, and can get 'vibrations' from living things.
Before he died and left his mansion and the Guardianship to his family, Augustus Skinner was the original international adventurer, artefact hunter, archaeologist and the original Guardian of Lost Secrets. He made sure to keep careful notes about all his missions in a Journal. He detailed descriptions of every artefact in the collection, including its powers, it's last known location, and its legends.
This journal is now an invaluable tool for the latest generation of Guardians... his grandkids. Having the journal is like having Grandpa Skinner along on missions with them, or the next best thing. It's a link to the great man, and an invaluable document.
As the mother of the Skinner boys, aunt to Tara and daughter of Augustus Skinner, Julia knows all about the Guardianship because she grew up adventuring to the four corners of the globe with her dad.
As well as a busy mum of teen boys, Julia is now 'mission control' at Skinner Mansion, where she provides all round support for each crazy adventure, including back-up research, motherly advice, encouragement and good common sense.
Wellington appears at first glance to be the 'loyal butler' – but he is actually much, more than the hired help. A sort of Man Friday to Grandpa Skinner, Wellington is a 'stiff upper lip' type who, in his many years of life, has had an amazing variety of experiences, ranging from a stint as a 'Red Beret', to a Formula One racing car driver, to a circus trapeze artist. It seems his services were inherited along with the mansion.
Obsidian Stone is the omega leader of the Shadowy League. This sinister man is obsessed with possessing every one of the legendary artefacts and using their powers to achieve his megalomaniacal pursuit of world domination.
His desire to find these undiscovered and mysterious artefacts is obsessive and relentless, and his resources are vast. He has all kinds of weaponry at his fingertips, as well as the latest technologies. It is our heroes' sheer heart and spirit that seem to confound him most.
