Macto himself is a close range no-magic fighter. On the other hand, Felicia is a magic all-around fighter.
Macto: Knows Muay Thai very well, can study environment to advantage, and can heal others using energy.
Felicia: Knows the 4 element magic, and some arcane.
Together: Knows each other's fighting style, can do some sick combos.

They fight best as a TEAM, not solo. So if you separate them, they could be in a whole lot of trouble.
Macto: Does not know much about other fighting styles, takes him a bit to analyze, plus no magic except the healing.
Felicia: Since her training was stopped early(Coming in story) She cannot do very powerful spells. E.G.: She can freeze people, but not summon a iceberg. If she does do a powerful spell, it might just be out of adrenaline,
and she will get tired since she took a lot of her energy. Therefore, she usually does weak-strong spells, not EXTREME or anything.

Story: Macto and Felicia actually met when they were very young. Playing together, plus their parents being good friends, they became best friends themselves.
However, one day, tragedy struck. When they were walking on a road, someone tried to rob them, and blocking a bullet for Macto, Felicia was severely wounded. Macto rushed to "The Hermit", known for curing things
like fatal wounds. The Hermit said he could heal her, but it would take a year or so. The bullet was not ordinary, so it took longer. Meanwhile, The Hermit trained Macto in Muay Thai, being from there himself.
He also tought Macto how to transfer energy to heal others. He warned Macto, though, that if he tried to cure a fatal injury, it might work, but either almost or directly kill him from the energy used.
Meanwhile, Felicia was in the spirit world, when she met 7 powerful magicians, who made her realize that she had great potential to become one of them. Mentored by each of them, she grew steadily, until her training
was interupted when The Hermit finally revived her. Therefore, she isn't as powerful as she should be. After training together to learn each others fighting styles,
They waved goodbye to the Hermit and Macto and Felicia entered the RHG, determined to find the shooter that almost killed Felicia.

(This shows their personal abilities, sorry it is a bit choppy because I am waiting for Flash and that last move is a powerful stomp)
