Adwaita is a Geochelone Aerio that mastered magic thousands of years ago. He's an evil mystic being considered as the most powerful sorcerer in the universe. He was slightly mentioned and introduced in Where the Magic Happens and is responsible for the death of Spellbinder, Charmcaster's father.
AppearanceAdwaita is a turtle-like creature with pink mana fire-like energy surrounding his head.
In Enemy of My Frenemy, the flames around Adwaita's head have disappeared and his head has turned the same color as the rest of his body.
In Omniverse, his appearance is slightly altered, with his head now being surrounded by a new necklace with long horns. His head is also wider with his nostrils larger. He wears red armbands with yellow cuffs at the top and bottom. He has donned a red belt with yellow cuffs, fitted with a bull skull at the middle. Beneath the skull is a small, red cloth.
Powers and AbilitiesAdwaita is shown to be incredibly strong when he has the Alpha Rune. Capable of doing spells without saying them, he easily defeated Gwen, Charmcaster, and Kevin. He was even capable of fighting Ultimate Humungousaur without being defeated.
Without the Alpha Rune, Adwaita is still capable of doing magical spells, but he was shown to be no match against Charmcaster when she held the Alpha Rune and easily defeated him.
As a Geochelone Aerio, Adwaita has all the standard weaknesses of his species, though he has less of a blindspot due to the position of his head in comparison.
Though the Alpha Rune did grant him great power, the price he paid was his sanity as it made him extremely irrational and violent.
Without the Alpha Rune, his spellcasting is greately reduced. Currently in his stone-figure form, he is even more helpless and at Charmcaster's mercy, though he still seems to be manipulating her, albeit in a more subtle fashion.
Prior to the original series
Adwaita got his hands on the Alpha Rune, an exceedingly powerful magical item (which was actually a piece of the Map of Infinity in disguise) and reached the interdimensional world of Ledgerdomain. He got corrupted by the immense magical power the artifact possesses.
The inhabitants of Ledgerdomain, though most of them were very powerful sorcerers and sorceresses, were unable to defeat him, and their leader, Spellbinder, was forced to send his brother, Hex, and his daughter, Charmcaster, to Earth in order to keep them safe. While he did that, Adwaita murdered him and took control of Ledgerdomain. He had also enslaved most of the people of Ledgerdomain to do his bidding.
Ben 10: Ultimate Alien
In Escape From Aggregor, Adwaita was briefly mentioned by Galapagus. Adwaita was first seen in Where the Magic Happens, when Ultimate Aggregor reached Ledgerdomain in order to get his hand on the Alpha Rune. Chasing him, Ben, Kevin and Gwen were forced to ask for Charmcaster's help in order to reach Ledgerdomain. When the group arrived, Adwaita immediately felt their presence and attacked them. Adwaita also used Spellbinder's voice to encourage Charmcaster to fall to her death (but the team stopped Charmcaster from doing so). When they got to Adwaita's citadel, a Pallorfang attacked them and died after falling off the edge of the land. After a feral fight, Adwaita was surprised by an attack from Ultimate Humungousaur, allowing Ultimate Aggregor to knock him out with a sneak attack and escape with the Alpha Rune. Ledgerdomain then started falling apart and Charmcaster, seeing Adwaita weakened, chose to stay behind to fight him and save her people.It is shown in Enemy of My Frenemy that Adwaita was so corrupt with power, he became insane and was not in the right mind in the end after his overthrow and loss of the Alpha Rune.
In The Ultimate Enemy: Part 2, Adwaita was seen in a flashback.
Ben 10: Omniverse
He has a short appearance talking to Charmcaster in Charmed, I'm Sure. He has been turned into a stone miniature along with an Unknown Stone Figure and is kept in Charmcaster's bag. Charmcaster is listening to his advice in her plans, but is still confident that she is in control of him, although Adwaita managed to manipulate her. His conversation with Charmcaster made Ben, Rook and the others think she's crazy.
