Second in line for that position would have to be Antfish. He gets the highest accuracy everytime he plays with them, and their playthrough of Dead Center with him is one of the few times where they had zero deaths and very few incaps. Simply put, Antfish is the anti-Taka.
And Starring: Little Kuriboh gets this type of credit in Dragon Ball Z Abridged. In the first season he was a guest star, only playing the narrator, by the second season he more or less became a main member of the group.
Gan tends to refer to Jun as the most useless member of Team Noble.
Car Fu: Lanipator is very fond of using vehicles to ram the enemies with in Halo: Reach such as the "hero truck". It doesn't always work, mostly because he'll try it using anything with four wheels—include forklifts and airport luggar carriers.
Casual Danger Dialogue: Half of the running commentary the team provides during their Let's Plays is this, to the point of arguing weather or not the virus that made the zombies would have infected Batman (it wouldn't), Superman, and who would be the cause (Lex Luthor and Braniac), while in a underground, flooded cavern, filled with zombies.
Companion Cube: Kaiser, Lani, and Gan all have their own cubes in Left 4 Dead 2. Lani's is Gnome Chompski, Kaiser's is propane tanks, and Gan's is gas cans.
Kaiser: "Oh, hey, he had a sword."
Lani: "I just had a fatal- WHEEEEREEE? Aaaahhh yeah, come to Lani."
Taka: "Oh God, Lani, just get a room with it."
Disproportionate Retribution: During Halo Reach, Gan gets annoyed with his team mates and starts killing them. Taka for his singing and Kaiser for shooting Gan's falcon. Kaiser is also blamed for numerous things, including Kat's death.
Karmic Death: On several occasions, one member of Team Four Star will try to kill a team mate (usually Taka) for slowing them down. Moments later, they themselves will suffer some sort of debilitating injury (frequently in the form of a Tank or Charger).
Keep Circulating the Tapes: Their older Lets Plays have been removed from blip, and until they get uploaded to their gaming channel on Youtube, it's up to the fans to keep those episodes alive.
Kill It with Fire: Lani's preferred type of grenade in LFD2. He gets a little too enthusiastic in Death Toll.
Manly Tears: The team's reaction in Halo Reach to Jorge's death.
A Million Is a Statistic: Averted with Taka during the Serious Sam 3 Lets Play, where he seems genuinely horrified to learn that the population of Cairo was killed during the alien invasion. Played straight by everyone Gan, Lani, and Kaiser.
No, You: In their Halo: Reach LP they discuss the concept of Space Europe which is shot down with "it's a massive land", to which KaiserNeko responds: "No, you're a massive land."
The only line in "A Moment with Team Four Star: Episode 3" is "No, YOU shut up!"
Rage Quit: Never directly invoked, but Lani said at Conneticon that this was the reason they stopped playing Serious Sam 3. According to him, when they weren't bored playing the game, they were raging from there being far too enemies swarming them.
