This page describes Kilik's Battle Style in each of the games in which he appeared.
In Soulcalibur, Kilik's fighting style is based on Seong Mi-na's, although many people think that Mi-na's was based on his. He uses the range of his rod to get at long-range and set up many combos that can put a short-range character like Sophitia at a disadvantage. He also uses the raw power sometimes, overpowering many of other characters' single strikes.
It's the same that Soulcalibur III.
It's basically the same as in Soulcalibur III, but he does get even more originality from his original style while still sticking to the same techniques.
It's the same that Soulcalibur IV.
Kilik is a mimic character, he uses only the male characters discipline. However, his son, Xiba replaces Kilik's Style.
