The original sin of Bendis is this, he aged up jon. Yet, after all these year jon doesn't know how to use a sword.After all the begging and pleading to learn to use a sword. He doesn't do it. That's blasphemy.if they are going to make this guy future trunks. He would be one lame trunks. A trunks without a sword. Smh! It's not like the superman sword doesn't exist.It's part of the mythos use it. Clark didn't want to learn fencing, jon did.
Clark gave up the sword. Jon on the other hand is welcome to use it.
Just change the design of the sword and we are good to go.
