Determinators are something I love, and knowing that I love it had allowed me to understand why I love some of the media, some of the stories, some of the characters that I do.
Let us begin with the definition of determinator as it appears on TV Tropes:
A character — good or evil, male or female, young or old — who never gives up. Ever. No matter what.
And let me tell you, if you’ve ever played a Dungeons and Dragons game (or specifically came across D&D related fiction), read a bildungsroman novel, watched anime or read manga, or uttered the term “Mary Sue” with regards to a male character, it’s like you’ve come across determinators, and plenty of them.
The hero that gets beaten but then rises once more, or who gets beaten, trains and then comes back, the hero who will not abandon their friends, the hero is a hero. Note, should a villain display these traits, and it’s actually quite common, we’ll call him persistent or a pest, which is also often about time-frame or due to the fact that this isn’t shown on-screen. Take for instance Ash Ketchum, the protagonist of Poke’Mon. In episode 5 his electric Pikachu is beatenby Brock’s rock/ground Poke’Mon, so he trains overnight and comes back in the morning with his dynamo-trained electric rodent to beat Brock. More commonly though, we think of determinators as those who do not give up within the scene, who get beaten but rise up once more.
