Suggested by iKnowledge Will Vandom is a pretty skilled fighter. She is her own energy source and has dozens of different abilities. She can basically use her energy to do whatever she wants and such a versatile power is very hard to stop. Korra is the Avatar and has her own elemental mastery, but I don’t think she will be able to keep up with Will. Will powers seem to grow stronger and stronger as she gets more experienced and while this is a close match now, it likely won’t be in the future if she keeps this up. Will Vandom wins.
