As an engineer--no doubt the Geth/synthetic version of a doctor--Buzz prioritizes health. As for strength, it only prioritizes that enough to function in combat but as its focus is usually support, its not that important. Otherwise, it doesn't really care about physicality--its asexual and doesn't care about appearance much. It does care a great deal about the Geth standards of belonging and family of course, as well as, unique to it, a feeling of security. Often the victim of Vahla'Zel's hacking and exploitation, it often feels vulnerable and broken. Overcoming this and pulling its poor disrupted processes back together is an important, if rarely successful, endeavor.

Its interested in love, wants to be appreciated and approved of and respected for the support it offers its squad, tries to avoid attention because its shy and fearful, values its friends dearly, and generally just wants to serve its purpose and be comfortable with and accepting of itself.

Peral is actually rather similar--asexual, filling a support and protecting role that necessitates prioritizing health over strength, and similarly wants to be respected, appreciated and approved of for the services he provides. As a leader protector on and off the battlefield, security is important to him as well--keeping emotionally healthy himself as well as promoting emotional health and security in his squad. More than that, however, he wants to be respected because if his squad doesn't respect him, they won't follow him. He needs their loyalty. He doesn't need a sense of belonging--as a leader, in fact, he'd prefer to be above rather than among--but family is extremely important to him, especially his little brother, Ricin. He also has some spiritual leanings, most notably self-sufficiency. He's a caretaker; he likes protecting and watching out for others and hates being on the receiving end of the same..

Ricin, augmented cybernetically as he is, tries to cultivate his synthetic-driven strength and vitality. His health--also a bit of a priority--would suffer otherwise, as well as his combat ability. Otherwise, he's very much not physical. He enjoys relationships, particularly familial (which are themselves a high priority) but his crippling shyness and many issues that are readily apparent leave him almost fearful of attention. Being so different, he also yearns to be normal and fit in more with his family and race, and ultimately strives to be self-sufficient, wise and confident, taking after Peral (or at least, how he sees Peral, which is admittedly rose-tinted by brotherly love and respect).
