Suggested by iKnowledge Zatanna is a powerful spellcaster, but this is a rough matchup for her. Asta’s swords can negate/reflect all magics. She can still use her spells to throw objects at him which aren’t made of magic, but he’ll be able to either dodge them or slice them apart anyway. Asta’s physical strength is incredibly impressive and will really serve him well in this match up. Zatanna just won’t be able to keep this match to mid-range where she would have a chance. Asta wins.
Suggested by iKnowledge Both of these two fighters are powerful spellcasters. That being said, Rias can fight more effectively than Zatanna from afar with her disintegration spells. Zatanna has better hand to hand skills so that could help her in a close combat situation but that would be incredibly risky since one hit from Rias would equal death and Rias is also no slouch in the speed department. She’s simply a more balanced all around fighter than Zatanna. Rias Gremory wins.
Suggested by IKnowledge Tsotha-Lanti is an evil wizard who opposes Conan. There’s not much data on his abilities aside from his reputation. It seems like this guy typically prefers to stick to the shadows and certainly doesn’t have as much actual combat experience as Zatanna. She has taken on many threats and even knows some hand to hand skills for when magic is not enough. Tsotha-Lanti is not nearly as versatile and his age ensures that he won’t be dodging any attacks. This will be a rather easy win for the reverse mage. Zatanna wins.
Zatanna is pretty good at using magic, but that won’t be enough to defeat the Dark Knight. Batman has a lot of gadgets and he’s also a better hand to hand fighter. While the magic would be dangerous for him, Batman’s speed and power can end this in one hit. He just needs to hit first. Batman wins.
