Hey, Benn, do you remember that one Ant (I forget what animal it was based on) that Killua fought after Gon fought that armidillo ant? It had tough skin, too. Maybe not as tough as Zazan's but it was still pretty tough. You remember how he defeated it? Constant jolts of electricity to one spot so it cracked and then he was able to pierce it. And I believe that Killua is fast enough to get close to Zazan and back without getting hit.
