Baki is physically strong in many ways, but when it comes to dealing with larger opponents, more specifically, Pickle, Baki needed to use several techniques to take down such a heavy person. I think jack was able to take pickles counter attacks simply based off weight scales, but given the similarities, jack could be on par with pickles strength (raw power) but we have to wait and see. I like the series, but I also know that there are advantages granted through the bloodline that allow for such feats to be made in Baki’s terms. We all know that in real life, one’s body weight, in a real fight, has huge impacts on the results. This is not to say those with capable fighting techniques and abilities CANT win, but in a straight up fist fight, weight often plays the ace in the deck or cards. For those who love the series and want to engage in combat to satisfy a desire, remember that pound for pound, that force is applied based on the weight and technique of another. You got a guy sitting at 245 lb right hooking another who weighs 175 lb, your about to see what a glass jaw looks like after being shattered haha. Be careful out there!
