Yo! I'm DragonSaurus, otherwise known as DSaur, otherwise known as Ruv. I've been reading on this site for about ten years now, although I still haven't actually published anything. That day is coming eventually though.

My fandoms are:
Pokemon:

Specifically PokeSpe and game verses. Anime is nostalgic, and I honestly didn't really like anything post-Battle Frontier
Fav Pairing: Either MangaQuest, Commoner, or Agency. Outside of Pokespe, the characters are too much blank slates for me to see two randoms getting paired.

Star Wars:

Namely the old continuity, you know, before Disney came in and mucked stuff up. Obi-Wan is and always will be my favorite character.
Fav Pairing: None. Maybe SiriWan. But only in small amounts. Because they never really can end up happy.

Percy Jackson and the Olympians:

Includes the other series in the Riordanverse, PJO is just my favorite.
Favorite Pairing: Percabeth. Hot take: Perachel is only bad because it would mean Percabeth would be broken, along with our hearts.

Magic the Gathering:

Not so much from the Fanfiction perspective, but I love the lore and the game itself. I've been a blue player for almost 20 years now. And now I feel old.
My favorite color combinations are Izzit, Dimir, Esper, and Bant. I love me my blue.
Favorite Format: EDH/Commander
Biggest Money Card: Underground Sea, in pretty decent condition.

Batman:

I came for the Dick. I stayed for the Dick
Fav Pairing: DickBabs

Young Justice:

I came for the Dick. I stayed for the Team and it being so incredibly cool at the time. Also the Dick.
Fav Pairing: DickBabs

Naruto:

Read all of the manga, technically haven't finished the anime. Rest in Peace hardcopy Shonen Jump, it guided me throughout most of grade school. And may my fond memories of the series never be consumed by my intense dislike for Boruto.
Fav Pairing: Probably Naruto/Hinata, but I'll throw in something from deep right field and go ahead and say that I really like Lee/Tenten. Also Lee will always be one of my favorite characters in the series.

Dragon Ball:

Might actually be the only one where I have read all of the canon manga and watched all of the anime. Gohan is my favorite character, and damn did DBS anime do him dirty.
Fav Pairing: Gohan/Videl, although it's more that I don't really care about pairings in Dragon Ball.

One Piece:

I enjoy reading it when Oda decides to give us actual story rather than endless filler. I'm one of the basic people whose favorite character is Zoro, although it's more me finding the way the world interacts with him, since he doesn't really interact with the world all that much.
Fav Pairing: I have absolutely no idea. Luffy doesn't care, Sanji is White-Knighting all the time for no pay off only to turn around and be a creep, and Zoro just doesn't care.

Dungeons and Dragons:

I've been playing it as long as I can remember, first played back in AD&D and had no clue what anything meant. Played 3.5 for a long time, skipped 4 to get to 5th edition.
Favorite Class: Rogue or Paladin

Super Smash Brothers:

I was really good at Smash 4, started winning my locals, then Ultimate came out and I haven't had the time to lab it like I labbed Smash 4.
My mains have been:
64: Kirby
Melee: Falcon/Pika
Brawl: Falco/Falcon
4: Falcon/Marth/Pika. Although I also went through times of maining Cloud, Zard, Mario, Greninja, Falco, Corrin, Kirby, MK, and Puff for a meme. I had a couple character switches.
Ultimate: Pika/Falco/Falcon, although I wouldn't exactly call them mains, they just happen to be the three I play as the most often.

I think that about covers it. If you have any questions, feel free to PM me.
