He’s a very focused individual with an attitude that allows him to set goals with unbreakable focus and willpower, but also being a very respectful person in the sense that he often shows politeness to his teammates and those around him. Through and through, he proves to be a powerful and capable Spartan, being the strongest physically in their fireteam and having a friendly rivalry between him and Spartan Monger.

Born on the planet Eiro, 2533, she was originally in the UNSC marine corps, and joined the SPARTAN IV program a year after its integration into the UNSC. Suki, being the oldest in her fireteam is quite cold, always maintaining nerves of steel and a calm and quiet disposition, but also being caring of her brothers and sisters in arms, while also keeping everyone in line. Her serene and ‘make do and mend’ attitude aids her in tough situations and encouraging the rest of her fireteam, making her part of Eta fireteam’s greatest foundations. Her stern personality and skill also allowed her to excel in times of battle during the war with the New Covenant until it’s abolishment. Just like her teammates, Suki is separated and finds herself alone in the ruins of the Redoubt of Sundering, a once Banished owned facility on the Zeta Halo ring.

Geno among his peers displays himself to be immature, careless and making jokes out of everything in most situations. But, when things get dangerous or serious, he is one of the most reliable leaders a fireteam could need,with his ability to quickly adapt and his quick trigger finger, making him a formidable ally or enemy. Geno is now pursuing the remaining Banished forces on the Zeta Halo ring installation like the other UNSC fireteams.
