Zed O'Brien

Zed O'Brien (ツェッド・オブライエン, Tseddo Oburaien) a stern merman with similar powers to Zapp, as they were both taught by the same master. Joins Libra after being abandoned in Jerusalem's Lot.

Appearance
As a 'Merman', he has yellow eyes, blue skin with black markings adorning his head & wrist-blades that extend backwards like fins. He wears a black, sleeveless muscle-shirt, finger-less gloves & green cargo pants with metal sneakers.

Personality
A stark contrast to Zapp, Zed is a decidedly serious individual who has little patience for nonsense, particularly those of his fellow disciple.

Plot
Z's Longest Day.

Zed is first seen flying a stolen plane towards Jerusalem's Lot with the severed upper half of a Blood Breed Elder pinned to the nose using his blood.

Despite the strain of restraining the Elder while piloting for hours, he engages the Elder alongside Libra, only to collapse from shock & exhaustion after his Master abandons him.

Later, while recuperating in a specially prepared tank, to Zapp's amusement, he introduces himself to Leo & remarks how yesterday was the longest day he'd ever had.

'''Run! Lunch!! Run!!!'''

Leo invites Zapp & Zed out for lunch but Zapp insists on choosing locations specifically to try and mess with Zed, who calls him out on this more than once, all the while maintaining his cool attitude.

After Leo suffers a nervous breakdown, Zapp & Zed drag him to Vivian's diner, where, after checking to ensure nothing weird could happen, they prepare to dig in to a well-deserved meal.

Just as they are about to dig in, an armoured combat suit falls through the roof, forcing Zed to drag Vivian out of the way, tossing her clear but only managing to avoid being squashed along with the food thanks to Zapp's use of blood Threads.

After checking that Leo & the other patrons are ok, they are spotted by Klaus, who enlists Zapp & Zed to help him fend off the 1000 Yakuza brothers, who are rampaging through the city. In the end, exhausted to the point of becoming incomprehensible the trio stagger off to a Sushi bar, where Zed reveals he dislikes eating raw fish.

Power & Abilities
Master of the Shinatobe branch of the Big Dipper Blood Battle Style, which allows him to manipulate his blood into a trident & thread, which he can then strengthen by channeling wind through them.
