Solluk
Vulcan
Str: 18
Solluk has almost never had occasion to make a display of Strength, but he keeps physically fit and comes from a high-gravity world. It would be sensible that he is quite strong.
Dex: 16
Solluk's nimbleness has been oft stated, contributing to his piloting, martial arts prowess, and his accuracy with a phaser.
Con: 16
Solluk again keeps physically fit and is from a thin-air world. I think this contributes to a high Constitution.
Int: 13
This is where I wish D&D had a TECH score, like Cyberpunk 2020 did, which would make it more appropriate for building a Sci-Fi character. Solluk is brighter than he thinks he is, but he's not a genius. He wouldn't necessarily be a very good science officer, for instance. However, he has an aptitude and love for technical things, and was shown over several posts to read technical reports and even software update reports with genuine interest long before he ever seriously considered a career in Engineering.
Wis: 8
So, I think Solluk is actually wiser than this, but his Wisdom is often on a delay. He is wise in retrospect. When he analyzes things later and understands what he did wrong. He is also prone to impulsiveness sometimes due to his emotions, leading him to do things that are not necessarily wise, or to not do things that would have been wise, due to fear and insecurity. Wisdom isn't useful if you don't exhibit it in the moment, so I give him a penalty here.
Cha: 10
So... how charismatic is Solluk? I think his earnestness and general honesty make him appealing to the right people. But I also think his insecurities and self-doubt could make him tiresome for other people. And when he does show self-confidence, he is often riding a wave of emotional impulse that can too closely resemble psychopathy (such as when he takes genuine enjoyment from combat... though he has the good sense to feel a bit awkward about it afterwards. He also routinely misinterprets Jada as being bloodthirsty even in instances when she is not, probably due to projection on his part.) Solluk is probably the cranberry of the personality world. A bit sweet, or a bit bitter, depending on who you are and what you like.
Comeliness (1st Edition Unearthed Arcana Throwback): 16
Solluk is modeled on Tom Hiddleston. So, he's a pretty good looking fella, in my opinion.
