@SkylerVedas I watched all of Invincible now I'm reading the volumes from #1 until however far it goes.
What comics or manga you reading at the moment?
It's also a huge hinderance on Luffy's durability. Since the Rubberness will disappear upon contact. While Armament haki ( or coc defense) could help.
Any hit will do considerably more damage. Luffy was in PAIN during their Impel down encounter and that was a simple slam.
