Comet

Appearance
Comet is a big dude. He's about as muscly as you can get. He has thick black fur, deep blue eyes, and sturdy limbs and tail. He has a pattern of white dapples across his face from the lower left side to the upper right, along with a white spike on his belly surrounded by smaller white dapples. He is very physically intimidating.

Personality
Comet is the brawn to Ruby’s brain. He’s dumb, muscular, and intimidating. He can think strategically, but why bother? That's what Ruby's for! Comet very much admires his younger sister for her skill and smarts. He is very loyal to whatever cause Ruby champions and is happy to fight whoever he gets pointed at. He's a little goofy, but when things matter, Comet can put all jokes and stupidity aside and equip Serious Comet. You don't want to meet Serious Comet.

Kithood
Comet and his sisters Star and Crescent were born to a fairly young she-cat named Sylvia. Sylvia had met Stormbringer, Comet's father, when she was a little kit and had tried to steal prey from him. The two had become pretty close friends over time and eventually settled down together and had Comet and his sisters.

Comet got along fairly well with his sisters. From a young age, it was clear he had inherited his father's large stature, though Star and Crescent both more closely resembled Sylvia's thin frame. While he was fiercer and better at fighting that his sisters, he was sensitive enough that he rarely hurt them.

One time when he was about two moons old, Comet managed to almost break his paw while play-fighting with Stormbringer and Crescent. This was unfortunate, especially since the family had been planning to move in the near future and they had been depending on Comet's strength and speed so that they could cross the street. As it was, Stormbringer would have to carry Comet, Sylvia would carry Star, then one of them would double back for Crescent.

It started out well enough. Sylvia set out with Star followed closely by Stormbringer with Comet. Then Sylvia ran back across for Crescent. She did not check both ways before crossing the street and got hit by a car. The people driving the car realized that they had hit something just as Crescent was running out across the street to get to her mom. The people caught Crescent and took both her and Sylvia to the vet as quickly as they could.

Completely shocked by the loss of his one true love, Stormbringer took the kits to the only place he could think to go- a nearby alleyway, the first place he and Sylvia had met. Unfortunately, the alleyway was occupied, but luckily, the occupant was a very friendly, kind-hearted tortoiseshell named Blink. Blink was awfully lonely and she immediately took a liking to the grieving tom and his two kits. Blink and Stormbringer quickly became almost-mates and Comet was happy to see his dad happy again.

It didn't last long, though, and Stormbringer took his kits and left before too long. Comet was sad to leave Blink and the happiness she'd given his dad. Clearly, Stormbringer did too, since he returned to Blink one moon later to find her expecting his kits. Well. Stormbringer did not want to stay in one place, but he couldn't just leave Blink alone. As a sort of compromise, he left Comet with Blink, making him promise to take care of Blink and her kits. Comet liked being responsible, so he agreed.

Comet never saw his father again.

He did fulfill his promise, though. He caught prey for Blink and was always looking out for her daughter, Ruby. He really liked his younger half-sister. She reminded him of Crescent with how small she was. Comet really missed his own sisters, so he tried to be the best brother he could for baby Ruby.

Ruby was a fighter. She loved sparring with Comet and Comet had to be really careful early on to not hurt her. Soon enough, she was hurting him. Comet found this odd, but also really cool. By the time she was three, she was regularly beating him. Maybe he was just going easy on her, but she was impressive.

When he was nine moons old, he started noticing Ruby vanishing every so often and he called Blink's attention to this. They found Ruby beating up kittypets. Not great, but whatever. Comet wished he had found out earlier so he could join her.

Comet's a great guy like that.

Adulthood
When Comet turned twelve moons old, Blink was killed by a Colony exile. Though Blink was not his biological mother, she had still raised Comet and her death hurt like crazy. Without her, he became single-mindedly focused on taking care of Ruby.

Ruby asked him to join her murder-hobo tribe. Comet said yes. Why wouldn't he? What part of his personality made you think he'd refuse? Besides, he had to take care of his baby sister. So yes, he joined the murder-hobo tribe.

The two of them set off to find their father, Stormbringer. They were unsuccessful.

When he was sixteen moons old, Comet and Ruby came across a young she-cat fighting for her life. Comet, with Ruby's permission, jumped in and saved her. The young cat introduced herself as Eclipse and Ruby offered her a place in the murder-hobo tribe (which, if you hadn't guessed, is Ruby's Group and what I will be calling that group for the rest of this backstory and probably Eclipse, Iris, and Violet's backstories too. Because it's funny.) Eclipse accepted and the two, now three, continued on their merry way.

~This will be filled in later~

When he was twenty-four, the murder-hobo tribe gained some medical attention in the form of the young but surprisingly talented Violet, a pretty black and white she-cat trained in medicine. They also got a bonus in the form of Violet's sister, Iris, a skilled hunter. Comet liked hanging out with them. He was pretty much surrounded by she-cats, but he didn't really mind. They were good company. Ruby was, of course, his half-sister and very cunning. Eclipse was surprisingly intelligent and interesting to talk to. Violet and Iris were young, but they had a few quirks that made them very interesting companions. All in all, life was good for Comet.

When he was twenty-five, Ruby sat down with him and Eclipse and told them that she had specifically let Eclipse join the group so that she could be mates with Comet. Comet did not like this, but Ruby was the boss. She was much smarter than him and far more cruel. Blood relative or not, Ruby wouldn't hesitate to kick him out of the group if it benefitted her schemes.

So Comet and Eclipse settled into a homey domesticity. Comet figured Ruby would want kits from them, but Eclipse was having none of that. She was not interested and Comet valued her opinion enough that he left her alone.

Until, that is, Eclipse had a conversation with Ruby ten moons later and practically begged him for kits. Comet was confused, but Eclipse seemed terrified and Comet was always trying to keep his mate happy. By the time he was thirty-four, Eclipse was very definitely pregnant and seemed somewhat relieved.

Comet was rather angry at Ruby for terrifying his mate so badly, but he couldn't let that manifest. Instead, he let it seethe and writhe within him, often lashing out at poor Eclipse, who had done nothing to deserve this poor treatment.

When he was 35, his kits were finally born. Comet did nothing, said nothing, and was not around when they were born.

Other Info

 * There are a few inconsistencies between this backstory and Ruby's, so pick and choose which details from which story you like better and treat those as fact. I can't wait to see the fights in the comments section (just kidding- please don't fight.) (Also, Ruby's page was written first if that changes your opinion.)

Trivia

 * Whoops, I made Comet too sympathetic.
 * This is outlined more on Ruby's page, but Comet and Ruby are descended from Fieldstar and Crest.
