Zack

Zack appears in Olympus Coliseum in Kingdom Hearts Birth by Sleep. A scan shows him battling Terra. It is currently unknown what role he will have in the story. Zack has also been seen being used by Terra as a D-Link.

Appearance
Zack appears to have been designed after his appearance in Crisis Core -Final Fantasy VII-, albeit looking a fair bit younger, and is sporting his original hairstyle of short, thick black spikes with bangs framing his face. Likely due to his appearance in Olympus Coliseum, he is wearing armor similar to that of Hercules, though his is grey, as opposed to Hercules's orange. Other than this additional armor, Zack wears his Soldier uniform of two silver pauldrons, black gloves, a brown guard over his abdomen that is worn overtop the armor for some reason, two belts over the aforementioned guard, and his blue pants and turtleneck (the latter two being significantly brighter than Zack's original navy-colored clothing).

Zack's brown, knee-high sandals also bear the vague design of his original black, knee-high boots, and he wears black socks underneath them. His eyes are a bright blue. Small parts of his outfit have had swirls added to them and his physique is slightly different, likely to fit more with the style of Olympus Coliseum. Finally, Zack carries his original SOLDIER sword as a weapon.
