jahad when we was in the hidden floor was as strong as baam when they fought but urek was already at top 10 power when he went there... that explains everything i doubt that jahad was able to reach that level otherwise he would have gone above 134 but he got scared and stopped climbing... we dont really know anything about urek origins anyway and so far from what he show us and what zahad show us he is stronger than him... Arie hon is close to zahard level he could put a good fight against him and still lost to urek easily so...
Data z is much stronger than bam, I don't know how you get knocked around 90% of the fight and be as strong, Bam said repeatedly zahard is above him in power and skill, thorn 1 is a multiplier especially ignited, if data wanted to beat bam he could've, he never intended to do that from the beginning.
Where did it say urek was top 10 at the time? he was just too powerful to copy perfectly, the cut off limit could've been ranker or mid ranker not necessarily top 10 in the entire tower, they are plenty of reasons for zahard to stop the climb, I doubt its because he is scared that too cliche, it has to be something big or personal to him, Gustang didn't seem scared of urek at all nor does the other FH, so I doubt he is beyond them even if he is stronger, they could take him as team and win probably.
Tog isn't like dbz where everything comes down to power level, it's comes down to who has the most hax skills and innate talent, zahard is clearly one of the most hax characters even at HF, he was a beast clearly next level and had depth to his powers, the guy did cosmos like nothing, he is elite in every position and physically dominating, he is broken as hell and only 2 characters are above him and their gods lol.
