STUBBORN: Mairead is a hardheaded Scottish lady and a teenager to boot. When she gets set on something, she will not back down and will even summon part or all of her IS. She does not like to have her ideas or plans changed once she has them and rather they are good or bad, it matters not, as she will do what she feels is right. This hardheadedness tends to make people angry at her for not listening to what they have to say, and has caused some to not associate with her.
QUICK TO ANGER: Mairead is one who is quick to anger when things do not go the way she likes or her way. She will get mad at people and things if something goes wrong and at people when she is laughed at for the phobia's that she has. Additionally, she also does not like being wrong and gets upset when she is. With being in the Multiverse now, there are many things that keeps her distracted and interested in learning about, which can and has gotten her into trouble.
ATYCHIPHOBIA: Mairead has Atychiphobia that have hurt her in her quest of being an IS Representative Cadet/Candidate. Since there is a possibility that she could be replaced if she does not do well, she has a fear of failure and this is one of the most strong phobia's she has. Due to this, she works hard and does the best she can, but still has the fear in the back of her mind. Additionally, since coming to the Multiverse, she is in a completely different situation and there are some things that scare her. Moreover, since she has Atychiphobia, she knows that if she fails, she will be removed from the IS Academy, have her IS taken and given to another and no longer be the IS Representative Cadet/Candidate and that scares her. To make things worst, when she does fail at something, she gets down in the dumps and is not one to be around as she disappears into her books. Therefore, she always tries not to fail at whatever is presented to her. Her phobia also causes her to not think about things that other teenagers think of.
ACAROPHOBIA: To go along with Atychiphobia, she additionally has Acarophobia, a fear of insects that causes itching. Whenever she sees one, she is always trying to run from it and she always has anti-itching stuff with her. But this is something that scares her greatly, next to Atychiphobia, and if she is itching, than she could fail at whatever task she is doing. To make it even worst for her, with the various races within the Multiverse, she is always looking over her shoulder. With Acarophobia, it is something that she tries to face, and usually it ends in comical situations of hiding behind people, rather they are taller or shorter than her as she runs for cover. This is even true when the IS is active, she is protected, but still has a fear.
RELIGIOUS: A minor flaw of Mairead's, but she was raised by her father within the doctrine of the Catholic Church and even though she does not do a lot of what a Catholic does, she still follows the basic rules and does her best to not hurt people. Although, due to both her hotheadedness and hardheadedness, she tends to speak things before she realizes it and then has to do her best to apologize to people and make up for any hurt feelings. Moreover she then feels the need to go to confession about the sins she has done.
BLUNT: Another minor flaw, Mairead is as blunt as a brick sailing through a glass window. While she is not intentionally trying to be rude, her bluntness can easily be mistaken for such. She is one that speaks her mind and she is not one to back down for an argument/debate/fight. Moreover, since she can summon her IS with a thought, or part of her IS, she can be quiet intimidating.
