Zack's first ability is Berserk, in which the player can deal more critical damage with the cost of getting more vulnerable to enemy attacks. His second ability greatly covers the first ability's weakness, which is the decrease of defense: Attack Deflector will sometimes guard against enemy's attack, therefore lessens the chance of getting hit by the enemy.
Zack's D-link's ability of Slot Edge could be an allusion to a large part of the Battle system in Crisis Core: Final Fantasy VII, which has you gaining temporary abilities and strengths via a system similar to a slot machine. Also, Zack's D-Link emblems are colored orbs, similar to Materia from Crisis Core: Final Fantasy VII.
