'''Narj:''' ''Of course it's worse!'' They only gobble you. The moopsy ''drinks your bones!''

* CorruptedCharacterCopy: Inverted; Vexilon is basically the GoodCounterpart to 343 Guilty Spark from the '' Franchise/{{Halo}}'' franchise. Both characters are the A.I. managers of highly-advanced ringworlds left behind by {{Precursors}} who also gradually GrewBeyondTheirProgramming, but while Spark was a delusional BitchInSheepsClothing tasked with managing a galactic superweapon, Vexilon is a completely sincere NiceGuy who has converted his ringworld into a safe haven for artists and poets.

* BeneathTheMask: In public, D'Erika seems confident and self-assured in her skill. In private, however, she's actually terrified that everyone will realise she's a pale comparison to how great her sister could've been in the same role.
* BigBrotherWorship: In a twisted way, D'Erika thinks very highly of Tendi, to the point of feeling like an InadequateInheritor to her position in the family after she left. It's also why she leaps on the opportunity to have Tendi rejoin the syndacite at her side.

* TheGloriousWarOfSisterlyRivalry: As Tendi's younger sister with more traditional Orion values and goals, she holds great resentment towards Tendi for rejecting their way of life. But she's also bitter at her for leaving behind the family syndacite to join Starfleet and forcing her to take on Tendi's former responsibilities.

* CainAndAbel: The Cain to Tendi's Abel. While Tendi is sweet, D'Erika is devious.

* StrongFamilyResemblance: She looks just like her sister but with longer hair.

* {{Hypocrite}}: When Wesley decided to tell the truth about what caused Joshua's death, Locarno accuses Wesley of betraying his friends, conveniently overlooking the fact that Joshua was also a friend who might've still been alive if it weren't for Locarno's ego.

* CosmicMotif: Star-motifs are all over the place in a space-based franchise like Star Trek but Locarno is notable in that he sticks to a motif of ''exploding'' stars. He headed Nova Squadron in the Academy, was kicked out when he attempts to perform a manuever that would've looked like an exploding star, dubbed his private army the "Nova Fleet" and eventually died by way of an explosion in deep space.

* YouLookFamiliar: InUniverse. Both were played in live-action by Robert Duncan [=McNeill=] and in animation they are still drawn very similarly. Rutherford points out that they look identical, but Boimler doesn't see it.

* EvilMakesYouUgly: Locarno is at most a couple of years older than Mariner, as they were at the Academy at the same time, and yet by the time they meet again 13 years later Locarno looks visibly and significantly older and more worn down than her, implying his lifestyle away from the Federation and Starfleet has taken a toll on his looks.

* YouLookFamiliar: InUniverse. Both were played in live-action by Robert Duncan [=McNeill=] and thus look very similar. Rutherford points out that they look identical, but Boimler doesn't see it.

* DivergentCharacterEvolution: He initially looked identical to Tom Paris (given that they are played by the same actor and were originally supposed to be the same person), but here he's gained a five o'clock shadow and scar while also going grey. Meanwhile, Tom is just an animated version of his appearance during ''Voyager''. The actor even gives him a slightly deeper, more gravely voice to help differentiate the character a little bit more.
