Suggested by Destroyer Alex Rider is a pretty resourceful guy but he won’t be able to deal with the Chunk. The Chunk is bulletproof against traditional guns and can spit out diamonds at such a high speed that he even tagged the Flash. Alex can keep his distance and stay reasonably safe for a little while but between the teleportation and gravity The Chunk will eventually manage to catch Alex. Once he does then I’m afraid that it’ll all be over for him. Chunk wins.
