@Temaraire "pressure" has evverything to do with impacts tho. Or more importantly the transfer of momentum onto the target. The faster the round the greater damge it does. Similary with the mass.
I never realized this but this titan is basically a fusion of zeke's titan. Erin, only had his head left when they transformed and is in control while zeke is the body
Treat this as a gag manga and you'll enjoy it. It is similar to one punch man honestly, with less drawn out battle.
Also LN has been officially translated to vol 2 which is goes a bit beyond the current arc
