Booster Gold shield vs Ikon suit.

A stress test of:

1. Crazy Cyke's GOML.

2. Those hulk busting adamantium bullets

3. Wolverines claws.

4. Fastball special, or whatever you call Colossus throwing Wolverine.

5. Thor's best hammer strike.

6. World War Hulks best punch.

7. Juggernaut, moving forward.

8. Dione's best attack.

Speaking just about Booster...
None of that's (Cyke's GOML, claws, bullets, fastball) getting through one of Brainiac 5's best inventions.

However

Thor's best hammer strike/WWH's best punch, would likely KO Booster -in- the FF.
Not sure what the dione joke is, i'm not in that loop fortunately.
