A little corny in some places, but not bad.

How would one go about submitting an SCP?

Gutrot could also defeat him cuz he an control all kinds of chemicals including sulfuric acid which is also an acid.

odd dialogue, and having each character be identified in text for every phrase they utter breaks up the flow. but the situation seemed to make sense, though I recall 682 being much less chatty. and it would seem prudent to inform Ben that 682 is only contained because it can't die, and succeeding would make Ben the greatest scientific mind The SCP has ever seen.

The most stupid crossover for the Fund that I have ever seen ...

Have Ben go against the "Child Breaker" SCP - 956. That one should hit close to his heart and should be hard to beat.

Scp-628 can't be stopped! Fucking idiot this is not fiction, this is a fucking tv in the 1700s!

oh there is gonna be some major philosophical clashes considering ben has a black and white view of right and wrong and the scp personnel re a bunch of terrifying psychopaths who do plenty of what we consider wrong for the common good

Scp-049 anyone anyone... Just me? Then what about Scp-106?

Can you do the shy guy

Okay, first allow me to say that the dialogue could be worked in better. Like for example, when one person is done talking and someone else starts talking, you could start a new paragraph. Plus, I feel some dialogue could have been worked on (an example is probably when SCP-682 yelled out his weakness for everyone to hear). But with that said, I action is very nice, the characters still feel like themselves (especially SCP-682 as everything he does and says... Well except for that one line... Do feel like how he works... At least from what I've read online), and I think it leaves enough room for any newcomers to the SCP concept curious and wanting to find out what else they can discover. So, overall, this opening feels nice, and I can't wait to see what happens next.
