Powers: (High Intelligence) (Brute Strength)

Description:

O’Connor is a dog-man (an example of a canine mutation). He’s a loner and he’s not really interested in saving the world. He’s out for himself and that’s that. He’s a bit of a coward and he doesn’t like to be in the spotlight. However, he was in the hot­el when the Happening occurred and later in the lim­ousine in the Presidential motorcade.

He’s in the right place at the right time, so what can he do? He’s been a soldier all his life and he might as well stick around and fight the good fight. Besides, he has a soft spot for the cute little girl, Lucy. In addition to his natural dog-humanoid abilities, he has the human traits of psionic Telepathy and Psycho-Kinesis.

Personality:

He is a bit of a coward, but he has a good heart. He likes to have a few friends around, to play a joke on, and to have a good time. He’s a pretty decent fellow. He’s a good sport and a good sport.

Combat:

If it’s left up to him, O’Connor won’t fight. If he has to, he’ll use his human and animal phys­ical attributes to fight, but he doesn’t like this. He might find it easier to use his psionic powers to get out of a tight situation.

Eventually, he became the primary inventor for the New World Guards.

He built almost everything they used, including their vehicles and analytical computers. He did this because he did not like the way the New World Guards treated the animal humanoids.

Powers: (High Intelligence) (Advanced Vision) (Ice Attack)

Description:

Xar is a rare mutation. Both his parents were mutants and they were very pleased to see their son become a fox-man. As a child, Xar had a hard time with others his age. He preferred to be by himself and to study. He was rather quiet and intro­spective. His mother tried to remedy this by getting him involved in sports and by encouraging him to play with the other children.

However, he still kept to himself. He never found anybody with whom he could warm up very well. One day he came upon a strange book. It was written by a man named Charles Fort. It told of strange happenings in the world and among the stars. The book provided ample evidence that the universe was rife with strange happenings.

Xar often sat for hours pondering these wonders. His mind was full of strange ideas. One day, during one of Xar’s meditations, the strange ideas that had been swirling inside his mind actually took on form. It was almost like he had created a strange energy that had given animation to his thoughts. This new energy gave him the power to see beyond the Human norm.

He could see things, far beyond the normal human vision. Xar continued his education. He quickly outgrew the small school in which he was taught. His parents were so proud, but they knew he was still discontent. At this time, the world was just starting to get back to normal after the Big Death. Not much had changed in Xar’s life, however, he was getting older and more frustrated.

Personality:

Xar is an intellectual. He is compassionate and caring. He enjoys his solitude, but can get lonely. He is very polite and respectful to others, but he is not much of a fun-lover. He would rather spend time in the library, researching the unknown. The joy in his life is in making new discoveries.

Appearance:

Xar is a pacifist at heart. If he must fight, he will do so only in self defense. He will try to use his ability to see into the future to avoid danger, if he can. If he must fight, he will use his skills in unarmed combat to his advantage.

Combat:

Xar knows that there are others in this universe besides humans. He has had himself tested and he does have latent psionic ability. With the help of this power, he feels he can be of better service to mankind. Xar hopes to use this power to help mankind in the future. It is the least he can do for all his parents have done for him.
