I don’t think so. Geno frisk has determination AND power. The thing about frisk is they can die an infinite number of times. The person they’re fighting only has to die once. The only way they can be defeated is if someone gets more determination than them. Which would nullify their powers a basically make them a regular ass 3rd grader. I think normal frisk could beat almost anyone not just genocide frisk. So I think Frisk beats the knight easily.
