Bobby is Lori's boyfriend, Ronnie Anne's older brother and Maria's oldest child. He has many jobs, such as pizza delivery boy, a pool lifeguard, a mall security guard, and a grocery clerk. Since moving to his extended family, he works at his grandfather's bodega.
Generally, Bobby has a relaxed and carefree attitude. He is an easy-going, kind, laid back, and wise person who likes to have fun and hang out with his friends. However, he can be altered or feel a bit depressed when Lori doesn't message or call him, or if something bad has occurred to her or his younger sister Ronnie Anne, both of whom he deeply cares for and is very protective of. If something were to happen that would cause Lori to dump him or Ronnie Anne to completely distrust him, he'd never be able to forgive himself.
Bobby is a very compassionate, understanding and forgiving person, but his naive and absent-minded nature can cause some turmoil and conflict. He tends to get himself stuck in the freezer at the Casagrandes' bodega, and often needs help to remove a blister or cure a burn after accidents during work. Despite his dimwitted aspects, though, Bobby can show signs of cleverness. He's shown to have good business smarts for his age, as seen in The Loud House episode "The Loudest Mission: Relative Chaos", in which he helped his grandfather run the bodega, and helped him arrange the store in a method to get more sales. He's also shown to be very thoughtful, and when he puts his mind to things, he can come up with complicated plans, like when he thought of a nice way to make his and Lori's relationship work, even after he moved in with his big city cousins.
Bobby is very dedicated to his work and tries to leave a good impression on people, especially his father Arturo as well as Lori. When something goes wrong and he messes things up in some way, he may feel depressed and doubt his skills (as shown in Stress Test) or even get episodes of paranoia (as shown in This Bird Has Flown). He sometimes shows fear that he may not be good enough for the people he cares about, or that they might ditch him and leave him behind altogether. As a result, he might push himself harder than he really needs to. Despite this, deep down he knows his family cares about him and will always turn to them for help whenever he feels like he needs it.
Bobby is as tall as Lori. He has tan skin, and black hair, with a tuft combed upwards. He wears blue jeans, brown shoes with multiple white stripes, a black belt with a gold buckle, and a cream-colored T-shirt under a green unbuttoned shirt.
Bobby's original design was quite different from its current design. In this one, he has a more urban outfit, including a bonnet covering his eyes and headset. He was also going to have freckles on his cheeks and more scruffy hair.
