At number twenty-four on my list, we have Lon'qu, Awakening's token dark and edgy Myrmidon in the vain of others like Navarre, Rutger, Karel, and Deen. Lon'qu joins Chrom's party at the end of chapter four at Arena Ferox. Impressed by Chrom's martial prowess, the West Khan Basilio offers his own champion to aid Chrom in the war effort. We immediately see that Lon'qu is stoic and a no-nonsense kind of guy with his character-establishing line, "He gives orders, I stab people. I think our roles are clear." However, when Lissa approaches him, he immediately tells her to step back, immediately making clear that Lon'qu has something against women.
This is actually a pretty interesting juxtaposition between Lon'qu and the character that inspired him, Navarre. Whereas Navarre has a code of honor to never turn his blade on a woman, Lon'qu seemingly avoids contact with them out of personal discomfort. The reason for this isn't immediately apparent, but through his support conversations, the truth comes to light.
In his supports with Cherche and Tharja, Lon'qu reveals that he grew up in the slums of Regna Ferox, presumably after immigrating from Chon'sin in Valm. While there, he grew close to a young girl his age, Ke'ri, presumably another Chon'sin immigrant. At one point, he and Ke'ri went on a picnic together, but were ambushed by bandits. These bandits killed Ke'ri, who took the brunt of the attack trying to save Lon'qu, and Lon'qu was powerless to stop them. Ke'ri's parents blamed him for her death, and Lon'qu fled the slums to honed his fighting skills at the Feroxi capital, fighting in duels to improve his swordsmanship. However, the incident also gave Lon'qu crippling post-traumatic stress in the form of a fear of women. His support with Panne even reveals he's kept awake by constant nightmares.
His gynophobia is often mistaken for misogyny, but Lon'qu doesn't intrinsically hate women, they're just his PTSD trigger. In the heat of combat and in life-or-death situations, he's able to suppress this instinctual repulsion, but in circumstances where his life isn't on the line, his condition debilitates him. In many cases, he has to speak to women from a distance to avoid discomfort, and is only ever able to help his condition by repeated exposure in his supports.
His support with Tharja offers him a way to eliminate his trauma, with Tharja offering to erase his memories of Ke'ri and his life before he fled the slums, but he declines, knowing that he'd be a different person entirely if she did so, as those memories were formative to who he is as a person. His support with Cherche, meanwhile, offers some closure on the Ke'ri situation. She tells him that she had met Ke'ri's parents while she was taking refuge in Regna Ferox, and that her parents no longer held ill will towards Lon'qu. After he had fled, they learned of how he tried to save her, and after finding their daughter's diary, they realized just how close the two of them were. Blaming themselves for forcing Lon'qu to flee, they felt immense regret.
Lon'qu also has a rather complex relationship with the West Khan of Regna Ferox, Basilio. Basilio had taken Lon'qu under his tutelage when the latter had fled to the capital, sensing a warrior's strength within him. Eventually Lon'qu had risen through the ranks and had become Basilio's champion and right hand man, but despite their closeness, Basilio also inadvertently represented an obstacle for Lon'qu. Basilio was the one man who he could never defeat in single combat. Never wanting to be overpowered by anyone again, eventually defeating Basilio had become a long time goal for Lon'qu.
This is showcased in his support with Gregor, who had once matched Basilio in combat and almost became the new West Khan. However, while Lon'qu wished to fight him, Gregor quickly overpowered him, with the latter recognizing Lon'qu's passion for overcoming Basilio clouding his focus.
This comes up again in his support with Olivia, another Feroxi character who served under Basilio as his court dancer. Basilio often performed a feat where he could cleave a vase of water in half without shattering the glass or spilling the water, resulting from years of practice and discipline. Noticing that Lon'qu was attempting the same trick with no success, Olivia offers her help in offering him some tips, since she'd seen Basilio do it so many times. After repeated attempts end only in failure, Lon'qu professes that he believes he'd never be worthy in Basilio's eyes, only for Olivia to reveal that Basilio spoke of Lon'qu's skill to no end, almost like a proud father would. Lon'qu takes this to heart, feeling more confident in himself.
His support with Lissa and Cordelia also shows that loyalty and settling debts are very important to him, with him looking after Lissa after being tasked to by Chrom, despite his feelings, and him agreeing to give Cordelia fencing lessons after she had gone above and beyond to help out the army, himself included.
In his endings, Lon'qu returns to Regna Ferox, once again serving as Basilio's champion. As a set of fun facts, Lon'qu's favorite food is cabbage stew and his skill with the blade made him really good at potato peeling by proxy. He also loves bugs, as he played with them often as a child. His name is derived from Lon, the Gaelic word for blackbird, and qú, which is Chinese for quiet or stoic. Blackbirds are often considered a bad omen, which may reference his past.
As a gameplay unit, Lon'qu is decidedly mediocre in the long run of the Awakening metagame, but he's quite usable early on due to Vantage patching up his durability issues somewhat. Lon'qu's major issue is that most of his potential classes don't offer any 1-2 range options in a game that's primarily Enemy Phase focused. The only offensive weapons he can use as a Swordmaster, Trickster, or Assassin are swords (locked to one range, barring the Levin Sword, which Lon'qu doesn't have the magic to wield well) or Bows (as an Assassin, but then he can't counter at one range). Wyvern Lord and Griffin Rider don't have this issue, but Lon'qu's non-existent bulk runs counter to these usually tanks classes, making it not worth the effort or the use of a Second Seal. He can perform well as a Dread Fighter, but not only is that DLC-only, but basically everyone performs well as a Dread Fighter. Swordfaire, Astra, and Vantage are nice skills at least. And he's got some great critical hit quotes.
In Heroes, he just recently got a new weapon with the Solitary Blade, which helps him stand out again after getting powercrept for years on end.
So that's Lon'qu, the highest ranking Myrmidon on my list of favorites, notably. Great character, sleek design, and undeniably cool.
