- “Oh, you didn't really think Kaos was the strongest Portal Master on the side of darkness, did you?”
- —Kaos' Mom
Kaossandra, usually refered to as Kaos' Mom, is the mother of Kaos and an antagonist in the Skylanders series. She never made a full appearance until Skylanders: Giants where she appeared in a family photo inside Kaos' Kastle. Later her shadow briefly appeared in the end after the credits shortly after Kaos returned. Kaos' Mom makes her full debut in Skylanders: Swap Force as an evil Portal Master like her son.
Before battle, Kaos' Mother displays a warm aura and a nurturing tone of voice towards her opponent, speaking to them directly as if she were their actual mother, though not without a threatening and assertive tone when explaining her position. Towards her own son, however, she is rather abusive and constantly puts Kaos down over his failures of conquest, flawed schemes and ego. She believes her powers as a Dark Portal Master to be stronger than that of her son and that this makes her a better ruler of Skylands than Kaos as she was willing to underhandedly steal that from her son. However, she did display something close to pride for Kaos when he abandoned her in her mirror prison to fulfill his own plan.
Unlike her son, Kaos' Mom tends to treat her underlings rather well, such as playing Skystones with the Wilikin and spending quality time with Glumshanks (complete with tea and snacks) and her other underlings rather than taking out her frustration on them. She is also more focused on calculated efforts, sending out specific minions and using kidnappings, only relying on all-out attacks when pressured for time, such as the Fire Vipers in her attack to Mount Cloudbreak. However, she does not easily admit defeat, and spins her failed attempt at conquering the volcano as successful as the Skylanders were banished, even if not by her hand.
As stated by Kaos (and demonstrated by her first two "appearances" to him in SWAP Force), she has a flair for the dramatic.
As a Portal Master, she possesses control over Portals in which she uses to teleport herself as well as hover. She also uses powerful dark magic, such as leviation, cause candlefire to explode, and telekinesis. Her most notable ability is her power to fire a beam of powerful dark magic from her hands, though this magic caused her to be imprisoned inside her own mirror when it was used against her.
Interestingly enough, she was already aware of, and capable of directly addressing, the new Portal Master, whereas Kaos was oblivious to them (and incapable of addressing them directly) until his empowerment by Traptanium in Trap Team.
Kaos's Mother often blamed Portal Masters for the problems in Skylands, and she wasn't happy when she discovered Kaos had Portal Master powers. According to the Wilikins, Kaos's Mother used to play Skystones with them before she left. A brilliant strategist with a strong grasp of Dark Magic, she has nevertheless been unable to fulfill her dream of conquering Skylands - a fact that greatly frustrates her.
Kaos' Mom had returned to her castle sometime during the events of Giants. When her son returned, she approached Kaos, and Glumshanks hid at the sight of her.
Skylanders: Swap Force
A hundred years ago, it was revealed that Kaos' Mom is a dark Portal Master and had launched an attack on the Cloudbreak Islands with a swarm of Fire Vipers at her command. The attack was repelled by the SWAP Force Skylanders, however the effort caused the Skylanders to be banished from Cloudbreak by the volcano's eruption and left the Islands unprotected for years.
Years later, Kaos' Mom contacted her son, Kaos, and soon scolded him for making his all-out invasion draw too much attention (an action which brought the attention of the Skylanders who had arrived to save the Cloudbreak Islands). She later came to Kaos' Kastle in person to help her son with his conquest, revealing to have gained the help of a few minions she had enlisted. When the Skylanders saved all the Ancient Elementals, Kaos' Mom interrupted the celebration and announced that their victory was far from over before saving Kaos (who was captured after his attack on the Fantasm Forest) and kidnapping the new Chieftess, Tessa.
In Kaos' Fortress, the Skylanders confronted Kaos' Mom, who taunted the young Portal Master by proclaiming herself as 'a true dark Portal Master' and planned to rule Skylands by herself once she takes care of the Skylanders. She then engaged them in a battle "they will never forget", summoning evilized creatures and unleashing dark magic upon the Skylanders.
After defeating one of her 'pets', Bubba Greebs, the Skylanders tricked Kaos' Mom into firing her dark magic onto a nearby mirror that was dropped down by Tessa. The magic bounced off the mirror and zapped Kaos' Mom, pulling her in and trapping her inside. Kaos' Mom, realizing that she couldn't escape the mirror, called out for Kaos' assistance, but discovered that her son had already gone to the Cloudbreak Volcano to fulfill his own evil plan, leaving his mother to her fate; something that Kaos' Mom is proud of Kaos for. She was left trapped inside the mirror as the Skylanders, Flynn, and Tessa moved on to stop Kaos from his evil scheme.
Kaos' Mom is distant from her son, said to have "never exactly been the picture of a loving mother" and the cause of his behavior according to Glumshanks. She attempted to abandon him several times and mistreated him constantly, and finds his soft spot for the Wilikins proof that he has no talent for villany.  Despite the fact that Kaos put his own selfish desires before his own mother and left her behind to be sealed away in her mirror, Kaos' Mom finally praises him for his betrayal in Swap Force, but as of SuperChargers still attempts to teach him by sending books through her prison.
Unlike Kaos, Kaos' Mom treats Glumshanks more nicely, and even notices that her son still mistreats the troll butler. It is frequently brought up that they used to meet to talk and have tea and cake.
- Kaos' Mom is well over a hundred years old, as it is mentioned that she attacked the Cloudbreak Islands in the magical eruption that took place before Swap Force's, already in her prime as a Dark Portal Master.
- Due to the game being made by a different game developer, Kaos' Mom was given a different character design.
- Her sudden status in Swap Force as an evil Portal Master conflicts with her earlier dislike for Portal Masters, as Kaos' Mom once blamed them for causing problems in Skylands according to the Skylanders: Giants Strategy Guide. This backstory plothole is the result of Swap Force being developed by a different game developer other than Toys for Bob, who are the creators of Kaos' Mom's original backstory.
- In the same strategy guide, Kaos' relationship with his mother was troubled, but not to the point of the new canon as seen in Book of Kaos.
- Her defeat is a reference to the defeat of Claudia, a villainess witch in the movie, A Simple Wish, as both characters were pulled and became trapped inside a mirror by their own dark magic.
- Kaos' Mom turned a female inhabitant undead, burned her castle to the ground and froze her village into a vast eternal glacier, despite telling the female individual that were no hard feelings against her for whatever happened between the two.
- In spite of being imprisoned inside a mirror forever, Kaos' Mom is still able to send self-help books to her son.
- Kaos' Mom bares a slight resemblance to the Maleficent from Disney's Sleeping Beauty.
- She makes a cameo in Skylanders: SuperChargers in a photo in Skylanders Academy.
- She is briefly mentioned in Ambush's backstory.
- Though Kaossandra's real name was initially created solely for the Skylanders Academy TV show, the name would later be retconned into her canon name in Skylanders: A Portal Master's Guide to Skylands. Though, according to Kaos, most people would rather refer to her in relation to him instead.
