what comics? 🙂 uncanny? uncanny is so strange.. cuz Kurt was 20 in 75 when he appeared first and now, in 2000 or dunno, when his father tells him his origin he is still in his twenties... and quite young. 🤨
but Magneto and Pietro looks like brothers cuz Magnus seems 30 years younger than his real ages...
it depends of the series
In yet another bid for ultimate power, Magneto was reduced to infancy by Mutant Alpha, one of his own creations. The young Magnus was transferred to Muir Island, where Moira MacTaggert attempted to control his rage by manipulating his DNA, in the hopes that the world would be spared Magnus' wrath when he grew up. Magnus did grow up, but faster than expected, as Eric the Red II used Shi'ar technology to bring Magnus to adulthood only a few months later. Magnus returned to his old ways, even going as far as destroying a Russian city with a rerouted magma flow and sinking the Russian sub Leningrad with all hands aboard. Although Moira's procedure would later be proven a failure, the "new" Magneto eventually felt remorse for his actions and turned himself over to the World Court, to be tried for crimes against humanity. Magnus would surely have been found guilty, except for the intervention of Fenris, who attempted to assassinate Magneto, Xavier, and Gabrielle Haller, the trio of friends who had foiled their father Baron von Strucker's plans years before. The courthouse was destroyed, and Magnus and Xavier were left alone as Xavier's body deteriorated beyond repair.
Well technically if you want to find out a character's age, you can't really just go by when they first appeared. Because of two reasons. 1) Some comics are based during different eras but come out at the same time 2) Each comic isn't going by our time, then otherwise all the X-Men would be in their 70s, at the very least
I think Pietor is around his mid early 30s
