Well, I'm just reading War of Kings, and I've been following Vulcan's story since Deadly Genesis, and back there he seemed so young and he really looked like a Summers brother, yet in War of Kings he lost a lot of his youth, and seems actually older with baggier skin?
I'm aware he lost vision in one eye and there's a scar, but that's not what I mean.
He simply looks... hideous... yeah, he seems uglier than in Deadly Genesis.
He seemed more manlier in Rise and Fall of the Shi'ar Empire, with more bulk and body mass.
The same for Emperor Vulcan. Though toward the end he seemed to show signs of his aging.
WoK seems to really put the age on him, especially Secret Invasion: War Of Kings.
