Final Fantasy VI boasts one of the biggest casts of playable characters in the series, and though Interceptor the dog is just a sidekick to one of those characters, he plays an interesting role in and out of combat.
Interceptor’s master is Shadow, the Ninja. Like all Ninjas in Final Fantasy, Shadow is actually pretty fragile, despite his relative strength. Even though he’s a master of stealth, enemies tend to target him rather often during combat.
Fortunately, Interceptor randomly jumps in and, well, intercepts the attack; he blocks like shields do, only more often. He also randomly attacks an enemy for Shadow, though it’s more adorable than effective in most cases.
Outside of combat, though, is where Interceptor gets really interesting, and it’s possible to completely miss how his story unfolds. At a certain spot before the game’s halfway point, the party meets Relm, a precocious young artist with a strange affinity for Interceptor, a dog who usually just tolerates Shadow and can’t stand other people. Relm lives with her grandfather and never knew her parents.
You can probably put two and two together from that information. But whether you see it play out in the game depends on a choice you make.
If you’re heartless and leave the Floating Continent without Shadow, his story ends (because he dies, spoiler alert). If not, and you make sure to speak to him at specific points, you learn about his previous relationships and roles in life.
And it’s all because of Interceptor, bringing people together like a good boy.
