Logan Cale/Eyes Only (Michael Weatherly)

 * Intrepid Reporter
 * Knight in Sour Armor - Lost some of his idealism over time. The prequel novel "Before the Dawn" shows that he was against killing bad guys and chewed Max's brother Seth out for doing so, but by the time of the series he's over it. Blaming himself for getting Seth killed, which he hides from Max until "After the Dark", may have something to do with it.
 * Knowledge Broker
 * Obfuscating Disability - After his walking problem is solved by an exoskeleton
 * Perma Stubble

Donald Lydecker (John Savage)

 * The Alcoholic - hasn't had a drink for 10 years when the show starts, but that doesn't last the season.
 * Abusive Parent - closest thing the X5s had to a parent.
 * Big Bad - in Season One
 * Colonel Badass - although following the Conservation of Ninjutsu, his badassery goes up exponentially when he's by himself.
 * Coup De Grace - delivers several.
 * Determinator
 * Enemy Mine - and he uses the associated saying
 * Establishing Character Moment: Lydecker establishes himself as both a Determinator and a complete dick when he goes to an Alcoholics Anonymous meeting for the sole purpose of telling them how weak they are. You see, when he gave up drinking, he did it cold turkey under his own willpower. He didn't whine about how he had a disease and he needed help. The irony when he later falls Off the Wagon is delicious.
 * Glasses Pull
 * Heartbroken Badass - after his wife's pre-series death.
 * Luke I Am Your Father - discussed and lampshaded. He isn't related to Max, but did include some of his dead wife's DNA in her.

 * Mr. Fanservice
