Veemon vs Zoroark
As Flamedramon, Veemon should be able to take Zoroark down in a fair fight. Zoroark is pretty quick, but powerwise, I wouldn’t rank him that high. Flamedramon is good in hand to hand combat and he can protect himself using his fire as a shield. He’s no slouch in the speed department either and he takes this win. Veemon wins.
