No, that wouldn't be a safe assumption.<br/><br/>Lobo and Superman are aliens, with physiology not comparable to a human's. Bane is dosed with so much Venom that he's practically not human, not to mention instances IRL where people cranked up on certain drugs cannot feel the effects of electricity/getting shot 50 times/etc. Slade doesn't fall under any of those categories.<br/><br/>Even as a super soldier, he has time and again been proven to be on the same level physically as Batman. Or, if we can to look at super soldiers, compare him to Captain America. Electricity still worked on them as well. Yes, they can handle it better than the average thug. But it still greatly hurts and stuns then (case in point, look at the elevator fight scene in Winter Soldier--the cattle prod that knocked a pirate out cold in a zap still stunned and briefly immobilized Captain America). I'm not saying that Slade should be knocked--I'm saying it is possible.<br/><br/>In all likelihood, if Nightwing's attacks land, Slade should be seeing stars. Stunned, zapped, and definitely in pain for a moment. Unconscious? No. But it would definitely leave an impression, and slow him enough for Superboy's coming attack to have a much higher chance of landing.
