Bard/Tony/Ro:
~Ro's main trait is APATHY but his secondary trait, which is carefully hidden by the first one, is EMPATHY. He tries not to care, but he can't help but feel guilty for his harsh words and actions.
~Tony's biologically female but he wears a sports bra, doesn't shave, cuts his hair super short, and wears baggy clothes all in an attempt to hide this fact.
~He has no preference between gender neutral or male pronouns, but he uses male pronouns for himself just because it's more grammatically correct.
~Bard adores his parents and his first two neutral runs were caused by the fact that he desperately wanted to reunite with them. His overwhelming guilt caused him to Reset and return to the underground in order to attempt to free the monsters with a Pacifist Run.
~He once attempted a Genocide Run but was unable to get past Sans and after dying countless times he gave up, Reset, and tried a different route instead.
~Ro hasn't managed to get past Undyne just yet, so he's currently staying in Snowdin. It's unclear where exactly he lives, however, since he doesn't trust any of the monsters enough to live with them and he doesn't have enough money to get his own place.
~It's likely that he's homeless and living in the forest somewhere, though no one's managed to make him admit it.
~He maintains that he doesn't have any interest in making friends, but he has an easy camaraderie with Grillby and The Man Who Speaks in Hands. He also likes Papyrus, Sans, and Monster Kid, but he tries to avoid them out of guilt from the past runs.
~Tony's has a deep tan, spiky blue hair which is naturally a dark brown, empty blue-green eyes, and lanky limbs that make him seem much taller than he is.
~His usual outfit consists of his spiky black leather collar, a pair of headphones, a baggy black tank top with a too-large furred red hoodie, a pair of white sweatpants and knee-high red snow boots.
~Ro has started to remember his original past before he fell into this dimension, which was some horrifying mixture of Underfell and Horrortale. He doesn't speak of it, but it's easy to tell when his amnesia is breaking down because he'll start screaming uncontrollably.
Flowey the Flower:
~Ro plucked Flowey from the ground the first time he saw the creature at the start of his fourth run through the Underground.
~Flowey gets around by wrapping his roots around the human shoulder and chest and ordering him about, though he occasionally dives into the dirt to rest.
~The former prince is actually extremely possessive and openly refers to Ro as his human despite rejecting the idea of them being anything like friends.
~They poke and prod at each other with hurtful, hateful comments, but that doesn't stop them from getting incredibly defensive and protective of the other if a monster tries to step between them.
~Flowey stays out of Ro's battles because he memorized their fighting styles a long time ago and it would be way too easy to win. (also because Ro asked him to)
~Occasionally Flowey grows incredibly annoyed and frustrated at being unable to understand emotions and will throw a violent temper tantrum if left to his own devices. Ro has gotten quite skilled at sensing this and will save before running to a deserted area and fighting Flowey until they both give up.
~He's quite mellow and almost tame after these moments, and though he never thanks Ro, he returns the favour by protecting his human whenever one of his 'episodes' occur.
