In Chapter II, Valkorion even lampshades this as he describes the Outlander's original companions in the least flattering ways possible. Even more so in Knights of the Fallen Empire as the Outlander recruits many companions from both the Republic and Empire, and even defectors from the Eternal Empire.The Inquisitor stands out with a literal soul-eating monster, a space pirate, a Jedi Padawan not on board with all the Jedi teachings, a flighty but very well-read Imperial archaeologist, and your Sith apprentice who has no concept of "tact", and whose ideas of "subtlety" are limited to "don't talk, be sneaky." Also the disembodied spirit of your ancestor, your former Master, and three dark-side Force wielders.The Jedi Knight has a plucky astromech who seems to think he's at least an honorary Jedi, a snarky Jedi Padawan with a dark history, an incorrigible ladies man genius doctor, a Republic trooper straying a bit too far into He Who Fights Monsters, and a full-fledged Sith Lord.On paper, not what you want in an elite SpecForces squad, but they get the job done. The Trooper crew may be the most normal compared to the others, but even they've got a Cathar Sergeant Rock nicknamed by the fandom "Grumpy Cat," an ex-Imperial By-the-Book Cop, a Played for Laughs Patriotic Fervor RepublicDroid, a spiritual tracker from an insectoid race who's also a Gadgeteer Genius, and a guy who joined the army as protection from the criminals who want him dead and continues his criminal activities as a member of the Republic military.Add the three bonus companions and most crews starts to look like the Star Wars equivalent of the diverse yet nonthreatening cast of a CW show. The Republic Trooper largely averts this, since all but one of their team is already a loyal Republic soldier. Some crews are merely collections of odd ducks while others are downright wacky. There's a Jawa (who in the original release had the tank role), Killik-Joined diplomat, jingoistic battle droid, a droid with the apporximate attitude of a Reaper.
It's BioWare many of the companion crews are gonna be this.
