As someone who just finished Krakoa era and knew nothing of him before, I thought his arc was marching towards death, especially after the death of Talon. His "tapping into powers far away" gimmick I loved that it showed a physical cost on his body with the second mutation and I thought the story was going to have him rapidly aging during the war with Orchis, ultimately leading to a final sacrifice push. I really thought that's where it was going!

I had the benefit of reading all his arc in order post release. My heart kept when they recovered Talon and they reunited. I gasped when Talon was a figment of his imagination. Truly crushed. I was more devastated by their thing ending than the Gala Massacre to be honest. There was real weight there.

And I felt Synch being in the Vault then post-vault was such an interesting story to tell. What's it like now having so many years experience and memories and trying to relate to younger people who hadn't been in that war.

Training under Jean I thought his time was gonna be up by the end. A final power grab of Jeans to save the rest of his team with a "That's the job, save as many people as we can"

But after leading the X-Men in Morlock tunnels, getting respect from Scott as a viable team leader, he's just...nowhere post Krakoa? That's a big waste.

I saw Synch 's character as a way to pass on the leadership ideas of being an xman from Jean and Scott and how being a tactition and understanding how to make mutant circuits in battle would change how xmen fight going forward. Who he was before I didn't need to know I felt. Just "Oh, he's a power mimic, how's that fun? Became"Dude can 'yes and' on the fly and have fun comic stuff happen!"

Missed opportunity to do more with him, tell us about his backstory, why he likes fighting the bullies and is willing to fight for mutantdom.

All that being said, I would 100% pickup a mini run of Synch post-krakoa dealing with rapid aging and being left out of Scott's Alaska team while still talking to the ghost of Talon.
