Villain Overview

Fink is a recurring antagonist of the 2017 Cartoon Network series O.K. K.O.! Let's Be Heroes. She is an evil creation and humanoid child who is also the minion and bodyguard of Professor Venomous. An evil creation and a mere labrat, Fink is the most favored experiment by Professor Venomous and she is treated as if she were his own daughter and she returns the favor by being his bodyguard at all costs. 

She is voiced by Lara Jill Miller.


Fink is a short green humanoid-rat creation with lime green fur and long, messy green hair. She has small ears and a long tail coming from her white colored dress. Fink also has light red scleras and has two eyelashes on both of her eyes and has a notable sharp snaggletooth on the right side of her mouth. She typically wears a lab coat with a skirt, dark gray boots, and a pair of magneta gloves. 


Fink has a very abrasive, impatient, and aggressive attitude, as she tends to act very argumentative, confrontational, obnoxious, and rude whenever she is around someone else in the presence of Professor Venomous. She is quick to insult anyone Venomous meets and tends to rough up anyone that gets in her way. Like her boss and creator, Fink loves to fight heroes and takes great pleasure in the act of fighting heroes and views it as a sport like Venomous. Her prickly and defensive nature towards Venomous stems from how he treats Fink like his own child and rewards her with gifts and is mentioned as being his favorite test subject. 


We're Captured

Fink makes her first major appearance in the episode "We're Captured" where she arrives as Boxmore with Professor Venomous for a business meeting and dinner party with his client, Lord Boxman. There, she has first introduced to Boxman, and acts very abrasive and defensive around him. She later takes Venomous' coat and heads to a locker room in Boxmore where she leaves Venomous' coat in there, but not before sniffing it out of admiration for him. She then pauses after hearing a sound from Enid, Radicles, and K.O. after they escaped from Boxman's trap, but she doesn't notice them and walks back to meet Venomous and Boxman who are eating dinner and were at the dining hall. Because of the trouble Boxman had with dealing with the captured heroes and preparing dinner, he found himself overwhelmed and the dinner food was burnt in the process and he was forced to serve it at dinner, much to the dismay of his guests with Fink being more open about how she hated her burnt dinner. 

As the dinner continued, Rad, Enid and K.O. dressed up as chefs and decide to ruin the dinner party as revenge against Boxman for capturing them. As they sabotage the event, Boxman snaps and uses both Darrell and Shannon to create a laser cannon and uses it against the trio much to the impressment of Venomous. As the latter delivers the finishing blow against the heroes, Fink jumps on top of the cannon yelling "Fire" as the last pie is launched and the three heroes are launched into the air in their first humiliating defeat. Venomous allowed Boxman to hug him as a reward for their continued partnership, when Fink interrupts the event by using a gun that shoots a giant fist against Boxman and knocks him out as an act of protection of her boss.
