Blue Typhoon:Initial internal fascination with these new aliens from Sinnali; she might pleasantly ask what species they were, having never seen their like before. The presence of Chris does earn a raised eyebrow from her (unseen beneath her blindfold) at having a child as a primary officer aboard the vessel, but she doesn't make any mention of it, given that she knows little about what alternate universe standards and customs might have influenced his position. Using the Force to scan the emotional states of the crew, she does begin anticipating the chance to poke at what makes their heroic optimism tick; and Knuckles is all the more interesting for being the exception. General Grievous mostly doesn't care about the Blue Typhoon except as quietly considering how much of a threat it could be to the Malevolence if push came to shove; he disdains that a child is in an apparent position of authority but doesn't say so openly.
Astro Mega-Timeship:Sinnali is greatly intrigued by the strange ways the Force moves around the vicinity of this ship's occupants, and if anything, she is almost equally intrigued by the fact that the Force clearly reveals the ship as being alive. Any reveal of Full-Tilt and Wipe-Out's presence earns a similar curiosity. Though, all of this is generally kept internalized except for a curious question regarding the Cybertronians' nature. She generally finds the Power Rangers' morph forms (if shown at the meeting) to be somewhat silly but doesn't openly express this (simultaneously acknowledging that Sith don't have a lot of room to talk on fashion) and privately cautions Grievous not to underestimate them, warning him about the strange way the Force acts in their presence. Sinnali does express some open amusement at Kai's reaction to the Malevolence, depending on if he expressed such a reaction where she could hear it.
Avenger:Presuming XCOM received enough of a lowdown on the highly diverse alien species in the Star Wars universe pre-arrival and subsequently don't have a particularly xenophobic response to the clearly inhuman party members at the meeting, neither Sinnali or Grievous have any particular reaction to a bunch of (to them) unremarkable militarized humans. While Sinnali does privately warn Grievous not to underestimate them (given how that often works out for him), neither the crew nor their ship's (comparatively lackluster to the rest of the party) armament provoke much interest. Sinnali is intrigued by the hard-broiled-ness of the crew's emotions but overall has seen such things plenty of times before; but she remains wary regardless, the Force warning that there's more to this crew than meets the eye in a surface-level glance. In the case XCOM does exude hostility towards people like the Mobians, Sinnali might speak up to pitch in on giving them a crash course about the species diversity they should expect to encounter going forward.
U.S.S. George Hammond:Similar to the Avenger, first impressions do not say much to Sinnali and Grievous beyond that these are high-tech laden humans. Comparatively, of course, they do acknowledge it has at least respectable firepower, such is its more notable armament. Depending on how much they lend to the tactical discussion, this impression is quite malleable, and the reveal of the Asgard Transporter would definitely elicit a metaphorical "sit up straighter" moment. It does not escape either of them how dangerous that could be if turned against them. Outwardly, Sinnali and Grievous express more interest in the fact that the George Hammond's crew are from the same universe as the Replicators (assuming this is revealed) and make extensive inquires on the enemy's tactics and capabilities.
The Republic:Sinnali mostly exudes amusement at any wariness expressed by the Republic, taking no small amount of joy in being unhelpfully cryptic and unwaveringly cheery even in the face of subtle -or not so subtle- threats. She diplomatically expresses her stance that the Replicators are a threat that is more than worth setting aside any grudges to destroy. She clarifies that this is indeed a second Malevolence, technically the Malevolence II from her universe, and as an olive branch, she reveals to the Republic where it is most likely being constructed in their galaxy. In the face of any intense questioning about her intentions, she remains perpetually affable and doesn't rise to provocations, and Grievous generally follows her lead -if with more unfriendly body language. She remains generally smug but never shows hostility and openly expresses her willingness to work with the Jedi and Republic peacefully... as long as they can afford her the same courtesy. Grievous just looms menacingly with narrowed eyes and generally exudes a sort of mulish resignation to working with the Republic -and especially Jedi.
Everyone:Knowing well that the Republic probably already knows about the Malevolence's Ion Cannon (depending on where in the local timeline this is), Sinnali is not shy about sharing its utility and danger with the whole group. While she doesn't frame it as a warning in the threat sense, the reveal could perhaps be interpreted that way by certain people. Outwardly, however, she reveals it with the claim that she wants the group to be cautious and heed warnings to steer well clear when it is fired. Sinnali pulls Grievous into this conversation as well, an area where he is notably markedly more comfortable, so they can get a dialogue going to discuss fleet tactics for the group and determine how they should all expect each-other to fight and work both with and around each-other's respective strategies. For Sinnali's part, the Malevolence II is pitched as a backliner, taking a battleship artillery role, with its main strategic focus to keep firing the Ion Cannons whenever possible and then gunning down the subsequently helpless enemy; Sinnali suggests the group stay alert for the Malevolence's firing warning and be prepared to fully disengage from the enemy to make room for the titanic ion ripple of a projectile.
