Considering how characters in Black Clover are faster than light,
Not everyone though. Very few have demonstrated the ability to move faster than LS, or LS magic users, though tbh there have been differentiations among LS in BC, i.e. Yami fighting a Light magic user
Yami easily reacts to his attacks
and then notes he got even faster
and Yami still manages to react to him and to block and counterattack
Though it should be noted that Yami has his own kind of FS/COO lmao
but yeah this was somewhat early series Yami and Jack definitely scales to that, so LS reflexes and attack and reaction speed, sure. Movement speed, not so sure tbh.
@Admiral Lee Hung @Seth what do you think?
Jack lacks the AP to put Kenpachi down in both rounds due to his far superior durability and endurance.
Thing is, but let me say first I have no idea how durable Zaraki here is, never finished Bleach tbh, that Jack cuts and cuts until he cuts through whatever defense. His magic is slashing magic, which allows him to use his magical attributes to generate blades of mana. As he fights, the blades adapt to his opponent's magic, improving his cutting ability.
Though the iffy thing for me is that Jack's blades adapt to match enemy magic, but I guess natural durability could be adapted to as well.
