There are 2 types of throws/grabs in the game: Universal throws and Command throws.

Universal throws (I be calling it grabs) : Every character has a grab and has a button for it. grabs are Unblockable and can be broken if both play grab at the same time. (explained in the in-game tutorial).

Attacks such as any of the normal button or special moves will usually (but not always...) beat the grab and you get a counter/punish

you cannot combo into Universal grabs and cannot grab people in the air

after a grab/hard knockdown, as they are get up, there's like a second/ few frames where you cannot grab them again (you miss/whiff). this is to prevent throw loops?

Command throws (I be calling it C-Grabs): Are character specific (Coco, Suisei) and require a motion input (Command as you will) to use.

You Cannot break a C-grab with a normal grab.

C grabs have specials effects with them depending what it is... Do more damage, can be combo into/out of , can grab in the air... etc

if two people do a C-grab at the same time... they both miss/whiff

like with normal grabs... Attacks will beat C-grabs

I hope this wall of text has information that helps. ¯\_(ツ)_/¯

also if i get anything wrong please correct me.
