Suggested by Destroyer Eric has a gun and he was willing to point it at Superman so the guy definitely means business. That being said, he would not be able to do a whole lot against the Chunk. The Chunk has his teleportation abilities an can even spit out diamonds at super speed. There’s nothing Eric can really hope to do against such a super villain. At the end of the day, the gun is really all that he has to defend himself with and that’s not much. Chunk wins.
