great stuff, Euro. loved it. Loved the standoff with Rypta and Grimm. Loved the unexpected appearance of "you know who." Loved the Vanguards shifting through alternate eras (some really cool variations there.). All the interactions between the two groups.
I do have two MINOR complaints: referring to Grimm as a meta in the story. It should be very clear: Grimm does not have the metagene and is not a metahuman. His powers are mystically based. Also, Grimm couldn't crack the table, but Ozzy could? Grimm is far stronger than Baxter, and would have shattered the table. . .
but like I said, minor quibbles. Overall, a really fun story and I was excited to see you return to it.
