Being the daughter of Loki, Zenaida has inherited half-frost giant enhancements such as speed, strength, senses.

Zenaida is glaringly, obviously and super/unnaturally stronger than humans. Because she is a demigod her capabilities are pushed beyond the natural level; making her immensely stronger than humans, nightwalkers and werewolves, though she is not as strong as some cold ones (strigoi). She is on par with the weakest cold ones.

Zenaida can move at supernatural speeds. Because she is a demigod her capabilities are pushed beyond the natural level; making her immensely stronger than humans, nightwalkers and werewolves, though she is not as fast as some cold ones (strigoi). She is on par with the weakest cold ones.

Zenaida can react and dodge objects travelling at high speeds. Because she is a demigod her capabilities are pushed beyond the natural level; making her immensely stronger than humans, nightwalkers and werewolves, though not as responsive as some cold ones (strigoi). She is on par with the weakest cold ones.

: Zenaida possesses super-human agility, such that she can react quickly, jump very high, climb, and run incredibly fast without difficulty or exhaustion.

Zenaida's skin, muscle, and bone tissue have many times the density of the same tissue in the body of a human being, making her extremely durable.

Zenaida has extremely keen and heightened senses of smell, sight, taste, hearing, and touch.

While not at a superhuman rate like the vampires, Zenaida is still able to heal much faster and more efficiently than a normal human.

Zenaida's advanced musculature is considerably more efficient than that of a human. As a result, her muscles produce practically no fatigue toxins during physical activity compared to those of humans.

Frost Giants naturally are able to live for thousands of years. It is possible that Zenaida has inherited this ability but the extent of it is unknown as she is the first human/jotun.

Not a greatly expanded ability for Zenaida as it is a jotun ability and there was more focus on her believing that she is an Asgardian, but she should be able to manipulate ice.

: Due to her Frost Giant parentage, Zenaida is immune to cold temperatures and any cold-based attacks, it is possible that because of this, she might be susceptible to heat and fire-based attacks.

Zenaida can alter the formation of her cells at will, allowing her to look and sound like an exact duplicate of any living being, including height, weight, and built. Her control and versatility are so refined, she can even perform partial morphing, such as only duplicating a person's voice, retina pattern or fingerprint to bypass security systems. She can also make herself look exactly like a person who is physically bigger or shorter than herself. Her abilities allow her to alter the colour and texture of her body, allowing her to mimic artificial materials, such as clothing. This is likely a magic-based ability, possibly due to the enchantment placed on her bracelet when she was a baby, though neither Frigga nor Loki understands why she is capable of doing this.

- Witchcraft:

Being born the daughter of Loki, Zenaida was born with the ability to tap into and wield magic from across the nine realms. Following her time on Asgard, Zenaida has a basic knowledge of Asgardian magic, though Frigga said she was naturally gifted.

Zenaida learned how to wield Asgardian magic from Frigga. Having only spent a couple of years learning, she is nowhere near the same level as Loki and Frigga yet.

- Zenaida can communicate with people via dreams, she has used this most often to communicate with Loki

Zenaida is able to cause objects to appear or disappear according to her will, oftentimes those she has previously acquired. As she is still young and has had little training, she can only do this on a small scale.

Zenaida is able to influence objects and move matter with mere gestures and focus. Again, because she is young and had very little training, this is seen on a small scale. Anything heavier than Zenaida herself and she struggles.

Zenaida has shown that she is capable of telepathy. The first time she used this was to communicate for a short time with Loki when noticing him as a child. This seems to be an extension of her magic, but it is something she has a bit more control and power with. Even Edward will note that it seems to be more effortless for Zenaida.

Zenaida can project green energy bolts and blasts, allowing her to strike, push, or blow away her targets. The blasts are powerful enough to send an adult humanoid several feet.

Zenaida has the potential to tap into various types of magic, it is likely she can tap into traditional magic.

- Abilities:

Zenaida is capable of speaking English, Norwegian, Swedish, Nordic, and Asgardian, as well as German, French, Spanish, and Vietnamese thanks to books and tapes she was given by Charlie growing up.

Zenaida is gifted in translating ancient nordic runes into English.

Zenaida has supernatural bodily awareness and control. This allows her to perform all kinds of leaps and spinning jumps/kicks with incredible precision. She can also slide over the floor at high speed and was even able to climb a pipe while being upside down with just her arms.

Zenaida is a skilled hand-to-hand combatant, having spent some time training in Asgard, she is able to take out multiple individuals with superb efficiency. Her dexterity and body control allow her to move with acrobatic precision.

Using her abilities and planning, Zenaida can escape and infiltrate different sorts of buildings and situations.

- Weaknesses

Preventing a witch from concentrating or giving full attention to their spells, may render them ineffective.

According to Frigga, one of the cardinal rules of magic is that disposition affects execution; this implies that performing spells correctly demands a certain frame of mind.

A hard and strong magnetic metal that is able to repress the supernatural power of a witch, supposedly rendering them powerless.

Despite being noted for their use of magic, witches are still susceptible to the effects of magic. This is inclusive of mystical objects.

There exist spells and potions that can kill witches, even when they are protected through powerful magic.

The excessive use of magic could lead to fatigue, unconsciousness, the depletion of one's reserves of power, and if taken to the extreme, death.

- Belongings:

Given to her by Frigga when she was a baby, Zenaida has an enchanted bracelet that sort of locks her appearance into that of something human. She wears this day to day to stop herself from accidentally shifting, though she has more control over it now.

Zenaida wears a gold necklace with a heart and snake charm, given to her by Loki.

Zenaida drives a 2005 Kawasaki ZZR600, much to Charlie's despair.
