Personality: A very cocky and evil woman. She thinks extremely highly of herself, and her abilities, and enjoys savoring her victories over her opponents. While she is quite vicious and ruthless, she does in fact, have a sense of humor; albeit it usually being dark and ironic thanks to her upbringing.  She finds genuine humor in people's attempts to change uncontrollable factors, showcased in her evil laughter at any attempts to oppose her. Despite her egotistical persona, she is also quite intelligent, and respects the few that are strong enough to put up a fight.

• Lightning manipulation: Jaakna's Doom Saber allows her to manipulate lightning, to either fire it off in a large bolt or combine it with sword slashes.
• Fire manipulation: Her Doom Saber allows her to manipulate fire, to either fire it off in a large concentrated blast, multiple smaller blasts; or she can also wrap fire around her sword to deliver scorching slashes.
• Wind manipulation: Her Doom Saber allows her to manipulate wind, to either fire off one huge powerful wind blast attack, smaller penetrating attacks; or she can wrap it around her sword to increase the range and cutting power of the blade.
• Combined elemental attacks: She can use her Doom Saber to combine any of the above mentioned attacks. (i.e. using a wind enhanced fire blast, or combining all three elements in one focused attack.)
