Second of all no proof of him being capable of overcoming Lucario's 4x difference before Lucario takes him out. You keep saying that he would surpass him because he went from low 7-B to High 7-A in weeks, and though that is true, it doesn't prove that Garou would evolve high enough Yes he's strong and has good instincts and reactions but all Lucario needs to do is punch him a bunch to win. Also yes, he could hurt Lucario with reflection. The problem being the fact that Lucario can predict it even better.
Lucario can literally read minds of people to determine their next attack and can use detect which does the same. Garou only has visual prediction and analytical prediction.
Also Lucario has laser focus which will let it land critical hits which often ignore stat buffs.
Also about mind reader, it looks into the opponent's mind, reading their movements, and locks on to them. Lucario's next attack will not miss, even if the opponent gets out of range and that is the actual function of the attack.
There's also reversal which deals extra damage based on Lucario's health.
Besides that Lucario can buff his defenses, speed (4x which is near speedblitz) and so on and so forth.
Garou is a tough opponent, yes, however Lucario has far better senses, the only thing lacking being instinctive reaction. Garou's instincts don't always kick in, he has a limit, especially if the opponent is continuously raising speed and defenses while landing critical hits/always landing hits via abilities.
