Yuka Suzuki

Yuka Suzuki (ユウカ・スズキ Yūka Suzuki), also known by his nickname Wave-Motion Yuka, is a former mage of Lamia Scale and one of Lyon Bastia's allies during the Galuna Island arc. He served as the guild anti-mage as his magic could cancel out others.

History
The only history known about him is that his family was a victim of the demon Deliora. It was for this reason he joined up Lyon on his quest to find the demon now trapped in an Iced Shell by Ur.

Galuna Island arc
After finding Deliora, Lyon then moves the demon to Galuna Island for a Moon Drip ritual that will unfreeze him. They however run into complications with Team Natsu who are on a unauthorized S-Rank mission, soon coming into confrontation with Lyon's group. After Lyon order his allies to destroy the village of Team Natsu's clients and fail when the team manage to save the villagers. Natsu Dragneel takes both Toby and Yuka on in the ruins of the village. Yuka decides to fight Natsu himself and has the advantage for a bit since Natsu can't use his magic while fighting against Yuka's. However Natsu finds a way around the problem by punching straight into the anti-magic shield. While Natsu can't use his magic in the shield, he has no problem using it outside of it. To which he uses his fire magic as a booster on his elbow, giving him the velocity he needs to punch Yuka through the shield and knock him out.

Fighting Festival arc
Yuka makes a short cameo at the end of the arc, watching Gray Fullbuster and Juvia Loxar during the fantasia festival.

Abilities
Yuka wields an anti-magic known as Hado (translates to wave motion hence where he got his nickname) which he creates energy waves from vibrations that nullify magic. He can also throw these waves as projectiles and create a shield around himself to block attacks. He seems to be able to manipulate the length and width of the waves. It also harmful to anyone foolhardy enough to punch straight into without magic (as Natsu found out). However while anything within the sphere is nullified, magic can still be use from the outside to help with the object that's inside the sphere.
