For those who are new here, I used to post scripts of my inner reactionary thoughts at each specific timestamp of a particular episode and upload them online to share with close friends. It's a fun way to analyze your thoughts about each specific point in the plot and comment about your favourite characters' actions, as if you are part of the episode yourself (hence the split reactionary OCs). To make it easier to comprehend, here's a list of my own pony OCs of the reaction series:
Cosmo: Smart, intelligent yet eccentric earth colt with a tendency to over-react, though does try to maintain rationale when things get too awkward, chaotic or frantic; often tags along with Sunny Starscout as her tutor
Alley and Bella: Twin unicorn colt and filly (respectively) who loves to tag along with Izzy Moonbow to see what type of zany shenanigans she gets into
Deputy Rocks: Eye-patch and peg-hoof wearing grey earth mare with a stern dedication to the law and the devotion to helping anypony in need; tends to get really serious and despises anypony who causes or creates trouble; accompanies Sheriff Hitch to keep the peace in Maretime Bay
Inspector Sandshoe: Former certified Royal mechanic of the Pegasus Engineer Corps and current Maretime Bay inspector; born with angel wing syndrome (abnormal wing development) that prompts her to construct a steampunk (and later dieselpunk) ornithopter backpack to help her navigate the skies; tags along Zip as her personal detective assistant and personal royal guard
Turnip Head: Former childhood pegasus friend of Cosmo and current tailor of Maretime Bay; loves to dress in fashionable styles, especially in his trademarked purple suit, white shirt, black tie and black pants; often accompanies Princess Pip as her personal marketing agent to help boost her popularity AND his tailor business by hoof-crafting expensive dresses
Tracefire: Brown unicorn mare with red double-bun mane; wears a black motorcycle jacket and swore allegiance to Opaline after she saved her from certain death at a New Yoke Alleyway; chides Misty for acting smarter than Opaline and only relying on her hunches and hypotheses; demands instant results and will not hesitate to commit violence to obtain her goals
