Martha (Zwei)

As a member of her species, she possesses:

Elemental Magic: The ability to use both wind and water magic.

High Intelligence: Unlike common lizardmen in other series, Mist Lizards are highly intelligent, capable of strategic thought, and are expert mercenaries.

Unique Hue: Her distinct blue-hued scales are a hallmark of the Mist Lizards, who are the kinfolk of the dragon Tomoe.

Pride and Respect: Martha takes great pride in her heritage as a Mist Lizard. She is extremely sensitive to insults—especially those from "Hyumans" who view her race as inferior monsters.

The "Punishment" Incident: In Season 2, Episode 10, when Makoto's students unintentionally insulted her, she dropped her instructor persona and brutally defeated them. This established her as someone who demands respect and will not hesitate to enforce it through force.

Loyalty: Despite her short fuse, she is fiercely loyal to Tomoe (her progenitor/master) and Makoto.

Raw Strength: Among the Mist Lizards, Martha is noted for having the greatest raw physical power. While other elite warriors like Liddy might have slightly better technical skill, Martha’s sheer force makes her a top-tier combatant in the Demiplane.

Ranking: She consistently holds one of the top positions in the Asora Ranking System, an internal leaderboard created to foster growth and competition among the different races living under Makoto's protection.

Instructor: Makoto utilizes her as a "sparring partner" at the Rotsgard Academy. Her purpose is to provide his students with a "reality check" regarding their actual skill levels compared to the powerful demi-humans of the wasteland.

While she is one of the strongest Mist Lizard warriors, she has a notable volatile temper when it comes to "bad things" being said.

Her reaction in the episode highlights this: The Insult: During a sparring session at Rotsgard Academy, Makoto's students unintentionally insult her.

The Reaction: Instead of a typical training session, she becomes enraged and brutally defeats them as punishment for their lack of respect.

Appearance Sensitivity: Like many demi-humans in this series, she is keenly aware of how "Hyumans" (humans) often look down on or fear her race, making her particularly intolerant of insults.

Despite this edge, she is extremely loyal to Makoto and Tomoe and serves as a highly effective combat instructor, provided no one calls her anything "bad".
