Full Metal Panic! The Second Raid · Primary Antagonist / Amalgam Execution Squad Commander

Gates is an Amalgam officer created for The Second Raid and one of the series' most openly unstable villains. He commands an execution squad equipped with Codarl Arm Slaves and treats both enemies and subordinates with the same casual cruelty whenever his mood shifts. The absurdity of his behavior does not make him harmless. Gates is capable of reading a battlefield, recognizing Mithril tactics and using civilians or local conflicts as cover for Amalgam operations. His violence becomes especially visible around the Xia sisters, whose refusal to follow Amalgam's orders turns them from assets into targets. Gates ultimately confronts Sosuke in Hong Kong, where the Arbalest's restored Lambda Driver overwhelms his Codarl. For once, Sosuke's control is stronger than the chaos an enemy is trying to impose on him.

Sousuke (Arbalest) vs. Gates (Plan-1058 Codarl-i)

Episodes 3-4 · Nanjing Tunnels · Gates Forces the Arbalest Back

The Nanjing rescue operation turns into an Amalgam trap, and Gates enters the fight in a Plan-1058 Codarl-i equipped with a Lambda Driver.
The Breakdown
Sousuke has the more famous Lambda Driver machine, but that does not make him the stronger Lambda Driver pilot. His ability to activate the Arbalest remains inconsistent, while Gates can bring the Codarl-i's system into the fight with far less hesitation.

Gates gains the upper hand, but the Codarl-i cannot sustain the engagement indefinitely and overheating becomes part of the escape window.
Why it matters
This is the moment The Second Raid proves the Arbalest is no longer a unique trump card. Amalgam has comparable technology and pilots who can use it more reliably.

Episode 13 · Hong Kong · Result: Decisive Sousuke Victory

After Kaname reaches Hong Kong and tears through the lie Gauron left behind, Sousuke returns to the Arbalest with a clarity he has been missing for most of the series.
The Breakdown
The difference is immediate. Sousuke stops fighting Al, stops treating the Lambda Driver as unreliable equipment and starts giving the machine the certainty it requires. Gates and the accompanying Lambda Driver-equipped Codarls suddenly face the version of the Arbalest everyone had been waiting for.
Why it matters
The finale is not a new upgrade. Sousuke wins with the machine he already had. What changed was the pilot.
