So a trait of my main character, Terrador, has been bothering me for some time. I've been debating if said trait is heavily Sue-ish, so I figured I'd bring it here for other's opinions. Now, as far as my knowledge goes, it's a proven fact that if your fan character has abilities equal or greater than that of a canon character, they're labeled as a Sue/Stu character. The subject in question is indeed about Terrador and Knuckles. The two definitely have some similarities in abilities, but Knuckles heavily outclasses Terrador in every aspect. Sure Terrador could possibly be a more strategic fighter, but he wouldn't even last a full minute against the Master Emerald Guardian. There is however one ability I know Terrador would be superior in, and that would be digging/burrowing. If those two were in some sort of digging race, Terrador would leave Knuckles in the dust, maybe even with the assistance of the Shovel Claw. Is having this ability better than Knuckles' considered being Sue-ish, or am I simply worrying too much and overanalyzing?
