In Season 1

• Gildar (played by wrestler RJ City under his real name RJ Skinner) – A narcissistic Canadian Viking who cared only about himself and constantly looked in his mirror, bragging about his muscles, facial features, and his hair, just like Gaston. His weapon of choice is a sledgehammer, and with it, he can rid the castle of his biggest hatred: sass from the attackers. In "Party Like It's $19.99," he was in a DVD of "Extreme Viking Makeover," and he published a book called Shoved by a Rainbow in "Shoved by a Rainbow." It is revealed in "Gildar Has a Secret," that he and Crocness were married. In "Talk To The Barrel" he fills in for Kook as he leaves for unknown reasons. He is part of the red team.
• Ballista (played by Samantha Brown) – A manipulative Canadian huntress who suppresses attackers with her physical beauty and deceiving charm. Her weapons of choice are a shield and sword. She also often uses a crossbow. Matt and Jason, from the Canadian version of Splatalot, are both depicted to have a crush on her. In "And the Splatty Goes To," she won the Splatty Award for Most Valuable Defender. She is often depicted as one who feels that the male defenders act like showoffs whenever she does something. She is part of the red team.
• Tinkor (played by Matt Burns) – A Canadian blacksmith who not only has built all of the Defenders' weapons, but his foul stench and appearance repulse everyone in the castle- attackers and defenders alike. His weapon of choice is a catapult, but sometimes he uses a handheld splatzooka. In "Beaver Tails," the attacker Sofia confuses Tinkor for his father Terry, who looks the same to each other. As shown in "Impossible is Nothing" and "Sarthak the Situation," he and Shaiden have a somewhat on-again-off-again relationship. His best friends are typically Kook and Skabb. He is capable of ticking Gildar off when the weapons do not work. He is part of the red team.
• Shaiden (played by Grace Francis) – A British ninja and Thorne's sister who is known for her sneakiness and her temper when another Defender, mainly Skabb, calls her a "little girl;" is constantly annoyed by the other Defenders, as she feels she is the only one focused on the Attackers. Her weapon of choice is a katana. She seems to have an on-again-off-again relationship with Tinkor and tries to tempt Kook into making a fool of himself. During the ending in "It's Taco Day," she uses meditation to calm Skabb down after he loses his cool when Erik captured the Crown of Splatalot. She is Thorne's sister both on the show and in real life. She is part of the blue team.
• Knightriss (played by Gloria Onitri) – A Black British knight and Madeva's older sister, who competes with Gildar as the leader of the defenders. Her weapon of choice is a jousting lance. In "Talk to the Barrel," she and Thorne are depicted to have a relationship, as they are seen flirting over their defense styles against the attackers. In "Revenge of the Nerds," she and Thorne are arguing over who should fire the splatzooka. In "Alan Skabb Tonelli," she begins flirting with Skabb bringing on yet another relationship for this indecisive knight. She can be quite threatening towards the attackers and can be rather aggressive towards them. She is part of the blue team.
• Crocness (played by Chenoa Deemal) – A cunning Australian Aboriginal swamptress who wears a crocodile around her neck and is known for her moss-covered hair. Her weapon of choice is a skull staff. Like Shaiden, she shows that she is on the edge who will focus on the attackers more than each other. In "It's Taco Day," she fills in for Gildar in the final round after he leaves the castle for a record label. In "The Cookies Crumble," Matt gives Jason a box of cookies that Crocness made, and they made Jason sick. She is part of the green team.

In Season 2

• Madeva (played by Alexia Khadime) – A crazy female Black British Dragonslayer. She is the new leader of the defenders. Her weapon of choice is a giant claymore. She is Knightriss' younger sister. She can be quite encouraging to the attackers as she often urges them to do well, specifically in the Cross the Moat round, but it usually appears to be sarcastic encouragement. She is part of the blue team.
• Vane (played by Eric Johnston) – A lazy, greedy and talented yet vain Canadian archer who would rather eat a sandwich than defend the castle. His weapon of choice is a crossbow-styled cannon. He wears sunglasses with his name on them. He often annoys the other defenders, especially Skabb and Thorne, for being unprepared or unengaged with the defending of the castle. He is part of the red team.
• Faetal (played by Nicole Power) – A charming Canadian Amazon who feels all attackers are her favorite. Her Weapons of choice is a dagger and shield. She is revealed to be Gildar's cousin in "Two Drawbridges Up." She is very sweet to the attackers, even if it is an act, and often encourages them to do well, but also often tries to distract them by asking questions or talking to them as they try to complete the round. She is part of the red team.

Round 1: Cross the Moat

Round One sees the Attackers challenged with overcoming a series of large obstacles consisting of barrels, the battle axes, the bridge of disaster, and the Defenders. They start by getting thrown into the water from a catapult and must cross the moat in order to possibly advance to the next round. This round looks at how long it takes them to cross the moat as the fastest six Attackers move on to the next round.

Round 2: Escape the Stockade (Ditch the Dungeon in the second season)

In this round the Attackers must go up a long staircase, known as the 'Loathsome Ladder.' The Defenders try to stop them from reaching the top of the stairs by using the trademark slime balls, a foam gun and the Vile Volley, a gun that shoots slime balls. There is usually always a Defender at the top of the stairs who uses the Purple Plague (a cart full of purple balls) and the Balls of Doom, very large green balls that are pushed down the staircase to knock the Attackers off. The fastest four Attackers to overcome the obstacles, ditch the dungeon and capture the four flags at the top of the stairs advance to Round 3.

Round 3: Capture the Crown

In Round 3, the remaining four Attackers must race across the obstacle-ridden courtyard and up to the tower where the crown lies in wait. In their path are all 6 Defenders from both rounds taking up various positions around the courtyard, wielding various weapons and devices to impede the Attackers' progress. In the end, only one Attacker will make it past the Defenders and capture the crown, winning this week's episode. Afterwards, they raise the flag with the Defenders clapping and the winner says the catchphrase, "I'm the king/queen of the castle" in Season 1.

In Season 2, they will choose a Defender to throw into the moat. They are not allowed to pick multiple and can only choose one to do this to. In the event of the night round, the Defender will be blindfolded on the Scary-Go-Round and will have to try and get over it, always ending up with them falling into the moat. The Attacker who wins the episode will announce which the Defender they would like to punish by saying; "My/Our first act as king/queen/ruler of Splatalot is to have one of you thrown into the moat/swamp. I/we wish I/we could do it to/it could be all of you, but today/tonight, it will be you, (insert Defender here)!"
