Frock

"'Hey there friend you're a real cool guy '""'You're the Honeycrisp apple of my eye'" Frock is the slash ship between Master Frown and Brock from the Unikitty! TV show fandom.

Canon
Master Frown is quick to see Brock as a "loyal henchman" for his evil schemes. This is most evident in "Stuck Together', where he is irritated with him offering cookies to Unikitty. He also has a tendency to demand Brock around, forcing him to come to the Doom Lords meeting, while also showing annoyance at him for bringing juice boxes to the meeting. However, deep down, Master Frown actually cares about Brock, such as in "Best Best Friends" when he apologizes to Brock with the latter's favorite song, keeping the lollipop Brock had gifted him at his birthday as a child as shown in "Trapped In The Tower", or in "The Birthday to End All Birthdays" when he hugs Brock with affection, but usually he is just to shy to show his true feelings for Brock.

Brock is more easygoing with Master Frown, treating them as friends rather than an evil duo. Despite this, he gets somewhat irritated at Master Frown's demands, as seen in "Stuck Together". When Master Frown yells for him, Brock is annoyed by this, since it was not necessary. He also likes to poke fun at his roommate, such as joking that his boss was angry at him because he forgets to do the dishes.

In the show, Master Frown and Brock share an apartment in Frowntown. The two often act like an old married couple. Since they were childhood friends, they know a lot about each other and Master Frown and Brock is shown to be really comfortable with each other. They have their own differences, but that doesn't stop themselves from having a good relationship.

In Season 3 Episode 18, Best Best Friends, the two had sang a song about how much they love each other called 'we're the very best friends'.

In the Series Finale, The Birthday to End All Birthdays Part 2, Brock was seen hugging Master Frown, much to Master Frown's delight. Brock then had kissed him on the cheek, with both reciprocating smiles and blushes.

Fanon
The shipping possibly first began when fans notice their cute interactions, especially after the episodes Dinner Apart-y, Beach Daze, Landlord Lord, and Top of the Naughty List, with Frock’s popularity catching on the most after Unikitty! Season 2 aired most of its episodes throughout February and March 2019. The fans really liked their dynamic, Master Frown as the wild, chaotic, outgoing one, and Brock being the domestic, nice, housewife™. Fans has a quick eye on seeing their relationship becoming more as a couple instead of being just friends. Fans commonly describe the two as “like an old married couple” with their more bicker-y interactions, usually surrounding chores or other small things in their home life.

Trivia

 * Unikitty! Director and storyboard artist Careen Ingle is the most notable staff on the show to directly contribute to Frock. Whether within the show through numerous iconic episodes, such as Dinner Apart-y and Best Best Friends, or outside of the show for the online community to pick apart, which includes multiple tweets and Tumblr reblogs of hers. She has always made content and hints to them as a romantic pairing as far back as February 2018, when the show was less than 20 episodes into its first season.
 * Master Frown and Brock have known each other since early childhood.
 * Master Frown gives Brock a “nighty night” kiss on the lips every night. While the former hesitates at first, he actively and willingly participates in this ritual.
 * Master Frown and Brock are roommates. Living together in Frowntown, the two of them share rent in an apartment together.
 * Brock has been shown to actively want to kiss Master Frown throughout the show. In Season 1 Episode 31, Beach Daze, Brock finds Master Frown in need of help on the ground and proceeds to perform mouth-to-mouth CPR immediately (paired with some romantic music in the background), even though Frown wasn’t drowning, let alone unconscious. In the Season 2 episode P.L.O.T Device, he’s briefly shown chasing Frown through their apartment living room, exclaiming “Come on, dude! It’s the power of love!” as he’s trying to kiss him, much like all the other characters are throughout the montage.
 * Master Frown has a tendency to give in easily to Brock’s requests, more tolerant than he is with him than most characters, such as Unikitty, that beg him to do things in a similar way. His response is typically “UGH! Fine!”. This is shown in the episodes Birthday Blowout, Dinner Apart-y, Landlord Lord, Top of the Naughty List (twice), and Sunken Treasure.
 * In Season 2 Episode 1, Pool Duel, Brock is shown to blush a faint purple when Master Frown is trying to convince the tombstone he has real abs and isn’t just wearing a shirt with abs on it, as he has throughout the entire episode by that point. The implication is that Brock found Master Frown’s eagerness to impress him specifically flattering and adorable.
 * In the Season 2 episode Brock Most Wanted, Brock blushes after Master Frown exclaims “I want the old Brock back, dude!”, as Frown doesn’t want him to stay a Doomlord. Brock finds this sweet because Master Frown accepts their differences instead of being forceful about Brock disliking parties and causing mayhem like him, which shows he’s coming from a place of genuine concern for Brock in this environment and a willingness to make sacrifices for their relationship.
 * In the Season 1 episode Dinner Apart-y, Master Frown is seen blushing as he looks up at Brock in a hug.
 * In the Series Finale, The Birthday to End All Birthdays Part 2, Master Frown and Brock hold hands before bringing eachother into a long embrace. Brock then proceeds to kiss Frown on the cheek, followed by them looking at eachother affectionately for a few moments, and continuing to hold hands and blush. This scene is deliberately implied to be romantic, and it can be assumed that this was the closure given to fans for where their relationship would go after the episode’s end.
