Chaldean Usernames:
Gudao = Ritsuka Fujimaru, Gudao came from "Guda", which was what his baby cousin called him when she first learned to speak because she couldn't say "Ritsuka."
GudakoBot = The auto mod bot that is named after the moniker Ritsuka gave his baby cousin as a comeback to his nickname "Guda."
Frisky1ntheFlowers = Merlin, I forget what lore of FGO video it was, but again, kudos to OtakuDaikun for the username lol.
Named Pokemon NPC Usernames:
Don'tTouchMyBuns! = Rosa (Female player character from B2W2). She doesn't like it when you do. Careful. Her mons became VERY protective of her after the events of B2W2, so don't try it.
DragoonRuleZ = Claire Ibuki, Blackthorn Gym Leader
Electrical★Streamer_Iono(MOD) = Iono (Scarlet and Violet Electric Type Gym Leader). Some of her fans have been complaining that she's been having too many "collabs" with Gudao as of late. There are even some rumors that she has a crush on him and is in a three way love triangle with PerfectlySaneHex, but in truth she's just the unofficial mom of chat.
Also, she's addicted to his content.
El_Kukui = Professor Kukui from SM and USUM. Alola's pokemon professor who specializes in pokemon moves.
Ecruteak_Gal = Kuni the Kimono Girl from the johto games. She owns a male Vaporeon that she loves very dearly. The day the Pokémon world was graced with THE VAPOREON COPYPASTA MEME, she went to the top of Bell Tower and screamed to the heavens her vow to never forgive the Anon who posted that meme on 4chan.
Gible_Archeologist = Cynthia, *Piano keys start playing* The Champion of Sinnoh.
Heart-of6old = Ethan Gold (Player character from GSC/HGSS(Johto), name is a mashup of two default names for PC).
KicksYouIntheFace193 = Bea (Galar Gym Leader from Sword and Shield).
MalasadaMayhem = Hau from SM & USUM, hanging around the player character from SM and USUM has eroded away his naivete and cheerful rival personality. He has gotten used to being poked fun at, not being treated seriously, and sarcasm. Hau is infamous for loving Malasada, to the point he could be seen as a worthy rival to Beni from Legends Arceus and his love for his Potato Mochi.
Mighty1Oak = Professor "You can't ride your bike indoors" Oak
PerfectlySaneHex = Helena, a Composite Hex Maniac from XY, Pokemon Masters and some doujins.
PsychicMoostache(MOD) = Sabrina's Elite level Alakazam, and is also her starter.
He is happily married(with offspring) to one of Sabrina's Gardevoirs who doesn't like battling.
ShortShorts_QUEEN = Hilda (Female player character BW). She is a proud member of the Comfy Shorts Club.
__Red__ = "…" Need I say more? Apparently yes I do, because Red exists in the story, Ash cannot. They have a platonic Curse of Separation thing going on(they can't be in the same plane of existence together). He's the former Champion of Indigo, and is still seen by many as THE strongest champion in Indigo's history. The only reason he stepped down was because of a lack of challengers aside from Lance, and he also got tired of being around cameras and fucked off to train in the wilds among the Alpha pokemon surrounding lands in between regions. He prefers to communicate via emotes-only in chat but they are almost exclusively all Ash ketchum/ pokemon anime related in some way. There's no shortage of them in Gudao's channel so he takes full advantage of it.
The-Undefeatable = Leon from Sword and shield, Champion of Galar and a major Charizard SIMP.
Top-Hat-PSY = Avery from Pokemon Sword and Shield Isle of Iron DLC. He is a psychic, but not really good at it compared to his family or other psychic trainers. Honestly, looking at his info, his family and backstory make him the closest thing the pokemon world has to a Magus in canon. A third rate Magus from a long lineage of magi, but still a magus, but nicer and less... well, nasu.
OC character Usernames (AKA NPCs)
Fyre&Flamez = OC Fire type specialist
GroundHippowdon = OC from Sinnoh
Guy_1n_Desert = NPC(undecided region but as his name suggests, he lives in a desert. Orre maybe?)
HippityHoppip650 = Celadon Gym Trainer
It's-ALWAYS-Pikachu = A guy who watched one of Gudao's clips on pokemon world's youtube and saw the "IT'S PIKACHU" meme and decided to make that his entire personality when he signed up for twitch.
IliekQTthings = A petite Fairy Type Girl trainer class OC in her mid-twenties. She never outgrew her adoration of the cute things as a child and to this day still dresses up like she did when she was 10.
JigglyWiggly = OC from Johto, I might have accidentally yoinked this username from another fic. I forgot the name, but I will update when I find it.
Junior_Researcher = Scientist Trainer Class from Kanto. If you haven't been paying attention, he doesn't believe in legendaries. He has spent much of his time with his face glued to a computer screen or a book to bother with going on twitch and social media until recently.
Ranger75 = OC pokemon ranger(undecided region). He is one of Ritsuka's more infrequent chatters due to his shoddy internet connection. Well, at least used to. Gudao is now his only reliable form of entertainment due to him being in the wilds and his stream is the only thing Ranger can watch without seeing a loading bar.
SeeDotbyTheSea = OC from Hoenn, specifically from Petalburg city.
Cameo Usernames that reference other fanfic characters
IronMunchkin = reference to Vicky Ferrous from Pokemon Trainer Vicky by Seras.
