Brawler's Grappling System

When grabbing someone, enemies can no longer immediately get away from you. They have to first go through a struggle animation, allowing you to do extra moves to them during that struggle animation. The struggle animation is very obvious and that is when you get extra options.
For the sake of convenience, I'll only be covering moves during the struggle animation. Brawler's grab system now allows for up to 6 front punches, by the way

Front Struggle:

□ will reverse them, making you grab them by the back of their neck and giving you different options. Can be repeated many, many times

△ will knee your enemy upwards and into the air

○ will trip your enemy, then stomp on their head

X will grab them by the face and slam them into the ground

R1 will Judo throw them

L1 will pick them up on your shoulders and slam them into the ground

Rear Struggle:
^To start Rear Struggle, you'll have to press X while holding them from the back of their neck

□ will sling them by the back of their neck into the ground

△ will pick them up entirely and sling them through the air

○ will slam them face first into the ground

Other Changes:

Front Punches now do more damage

Bosses are effected differently by grabs than most goons
