C3P0 is always appeasing, speaks in a high quick voice and bends over to serve everybody he sees to the point where he has no principles whatsoever - happily serving Jabba the hut, constantly deriding his friend R2 in front of those he sees as superior (everyone) He is repulsive from a personality standpoint and probably thinks of himself as perfectly nice and loyal and useful with lots of value but he’s actually none of those things.

Han Solo, perfect balance. Is reliable and heroic when you need him, is loyal when it’s earned but is confident, almost too much, in himself and his abilities and doesn’t take stick from anyone whatsoever. He’s charming but human, rebellious but a genuine good guy who cares but is fun. Perfect balance.

Luke Skywalker is slightly too beta, yes he’s good looking and naturally gifted but totally asexual and often his whiny interior exposes itself. He learns the game and alphas up a bit by Return but he is stiff and almost awkward, like a born beta who’s learned game and is emulating an alpha, but when it comes down to it is boring and a bit weak, but has some redeeming qualities.

Darth Vader is pure alpha dark triad. Zero empathy for anything beyond his own wants and goals. Is dominant in all situations and literally answers to nobody. The only person above him he throws into a reactor. He is so masculine and dominant that he renders himself asexual because you’re always on edge and genuinely unsure about your safety. He wears black leather and likes to choke but once again, MAYBE only mentally Ill people would find him attractive and it would be more for the risk than anything - but he’s a DAMN sight more likely to no pull than C3PO

So lessons? It’s better to be too alpha than too beta, but a good guy with alpha qualities and a fun charming personality will always win over the super intense but bland beta overworker try hard or psychopath dark triad.
