Remember these guys? https://marvel.fandom.com/wiki/Cereb...en_(Earth-616)
Considering Cerebro's recently rather attached to Charles head and the background information we are gettin. This seems very relevant though I haven't seen it brought up yet.
Cerebro gained sentience and wanted to catalogue every mutant on Earth. Wait doesn't this sound very familiar? That seems to be what we are being told Xavier pushed for it to do back then minus the whole being alive thing.
It ended with Charles purging the systems and robotic body being destroyed but after that?
I'm still a bit miffed it was the last we saw of Cerebro's X-Men team. I still think they had really cool designs and would have been interesting to pop back up. I especially liked Crux.
