So narrowing it down:
 * Orbitons: "bravado of a leading man" (LEGO's Niksput bio)
 * Infernites: Flain; no 2.0 leader as confirmed by LEGO
 * Glowkies: Globert leads the Glowkie show, voices the max, and takes a very big leading position in "Moon Madness" to the point it's pretty obvious
 * Klinkers: "Yes, boss." (Jinky and Kamzo to Gox in "Quest for the Mixamajig")
 * Frosticons: Flurr; no 2.0 leader as confirmed by LEGO
 * Lixers: no leader - see the answer of from LEGO on Dadaw's post. They took it from our wiki, yes...but now it's official text so you can't fight it xD
 * Weldos: "Kramm is the Weldos’ energetic leader." (LEGO's Kramm bio, hey look, something straightforward)
 * Glorp Corp: Glomp; no 2.0 leader as confirmed by LEGO
 * Munchos: More of an assumption than the rest, but Berp's a waiter and Snax is a kid. Vaka-Waka takes a bit of a leading position in "Quest for the Mixamajig" so it's the most likely.
