It's Superman vs Cyclops, but with a twist!
No h2h or Arena here, just a good old fashioned beam-off! Current/most recent comix versions of each.
1) Sheer power: side-by-side, Clark and Scott separately eye-beam progressively more durable targets, starting with an I-beam of steel and moving up to harder and harder substances. Where do each one stop?
2) Precise skill: Clark and Scott have to show they can use their eye-beams for something other than destruction. Best non-lethal use of eye-beams for each?
3) Screw it, Clark and Scott turn their eye-beams on each other (standard gear allowed). What happens?
