1. Astro's able to tank more than just meteors.

2. Gravity Hold won't make a difference. Sure it would've slowed Astro down a bit, but not by much.

3. Wouldn't really matter since all he could use during Flash Stopper would be his Mega Buster, which had been proven a bit ineffective against Astro.

4. Astro's able to tank over 1 million watts of electricity and I don't think any of Rock's electric weapons are capable of generating that much electricity at once. Also, the Atomic Fire blasts were uncharged and not solar power level, meaning that Astro could take the hits from it.

5. Okay yeah, I think that there should've been at least once shield weapon, but I think the Mirror Buster was effective enough.

Not sure about that Duo statement since I never played Mega Man 8.

In the end of the day, Astro has more horsepower and speed to him whilst Rock only really has weaponry on his side and doesn't even come close to Astro's strength (And no, Super Arm doesn't count since it's considered a weapon, an ineffective one at best).
