Dr. Krad Dusk, a mad demon scientist, builds all sorts of weapons that combine magic and technology. Nearly ended up destroying the world to punish everyone for the way he was treated but then settled for becoming a war profiteer when that didn't go according to plan. Also invested heavily in making his giant spider creations for fun and for use as protection.
Vs Art Jones, a musician gifted with wind related abilities such as compressed air blasts, tornado creating and using wind to speed up. His director, Nero the iguana also is more than he seems to be... Think Scottish Kazuma, with bagpipes!
In a fair fight, Art easily wins, giant spiders don't like getting caught in tornadoes. Playing dirty Krad has better chances of winning with traps, special weapons or using some of his creations, but still could lose, it's hard to say who'd win, would be far closer.
