moving command grab - projects the character a distance before they attempt the grab.
ranged command grab - exclusive to Super Skrull, he has a very far reaching ground throw.
ranged anti-air command grab - exclusive to Nemesis and Super Skrull; they have grabs that can grab airborne opponents from afar.
level 1 hyper grab - a command grab that uses 1 meter. Thor’s is invincible and can be used like a reversal. M.O.D.O.K.'s is similar, but is much slower, and can be jumped out of the hyper flash, so limit it to punishes only.
level 1 anti-air hyper grab - grabs opponents out of the air and is invincible for a brief moment at the beginning frames of the grab. Exclusive to Frank West at level 3+ and She-Hulk.
level 3 hyper grab - powerful grabs that require 3 meters. All level 3 grabs except for Nemesis’ are invincible on start up. All level 3 grabs cannot be jumped out of after the flash.
