This review contains spoilers
Alien: King Killer #3 begins with “king killer” Idris, imprisoned by his brother Zain (but only because he tried to kill him too). Zain is astonished by Idris’ behavior, especially killing their “brother” Amir, a cruel tyrant. Idris has no love for his adopted siblings or their “father”, the mad scientist who experimented on them and created this world, Sovryn, populated by enhanced Xenomorphs.
Idris rejected their late father’s programming, and he is outraged that Zain’s has openly embraced their father’s twisted legacy. After some more back-and-forth, Zain releases Idris (and returns his special sword) as they tour Zain’s compound. The people appear to revere Zain, but Idris still has his doubts, although his approach is different than Amir’s.
An alert sounds as Xenomorphs breach the compound. Zain and Idris stand back-to-back against the Xenos, their weapons and genetic enhancements making short work of the monsters. Zain uses the attack to convince Idris to join him and keep his people safe. Unfortunately, Zain overplays his hand by allowing Idris to witness a tithing ritual where a name is called (a pregnant woman) for sacrifice.
Alien: King Killer #3 ends as the outraged Idris calls Zain out and the brothers prepare to battle to the death, but the pair are violently interrupted by the arrival of the White King, their sister Aisha.
Analysis
Alien: King Killer #3 provides a bit of whiplash to readers as king killer Idris goes from his brother’s prisoner to his ally and back to his adversary within the span of twenty-two pages. Writer Saladin Ahmed uses the brothers’ conversation to fill in readers on Idris’ painful past and Zain’s present day.
Zain comes off as fair-minded, giving Idris the benefit of the doubt, despite his king killer past. Zain is a more subtle breed of tyrant as his subjects appear to embrace him at first glance, but their constantly calling him “your grace” and the cruel tithing put him squarely in the bad guy camp.
It’s likely Zain thinks he is actually doing the right thing with his people, while Idris raises poignant questions surrounding their father’s work, which includes the desolate world Sovryn and the Xenomorphs. Incidentally, the Comics Giveaway Day special from Marvel Comics offers an all-new flashback featuring all four siblings and the good doctor.
As with most stories in the Alien franchise, the Xenomorphs are never as dangerous as the humans and synthetics who band together to fight them. In Alien: King Killer #3, the Xenos are almost an afterthought. However, their deadly presence is felt throughout the story, even without the attack on the Green Compound. Xenos are a force of nature and survival against them usually comes at a steep cost.
With the arrival of the White King and her army, who viciously attack both Idris and Zain, are the brothers forced to team up again against a common foe?
Artist Carlos Nieto provides some stunning visuals, (with help from colorist Mike Atiyeh), from the flashes of energy from Idris and Zain’s eyes to the heavy use of green (of course) throughout the story, not to mention the bloody and violent Xenomorph attack.
Zain’s compound is well-rendered, shown in detail to be a former Earth-style city with buildings, overpasses among the modifications Zain’s people have made. There are also the compound’s gigantic walls that unfortunately are not entirely Xeno proof. Nieto’s fight choreography is impressive, also enhanced by Atiyeh’s color palette (green energy blasts).
Final Thoughts
Alien: King Killer #3 provides a few clever twists, shocking violence and redefines the concept of sibling rivalry. The pacing is brisk and the art and color are impressive.
