Silver Surfer - from the Silver Surfer Cosmic Power Blasters line
Air-Walker - custom made from Maddrox Multiple Man figure base, milliput details, fire wings are accessories from X-Men 2009 Halloween Jack
Galactus (in back)- from Marvel Legends Series 9, aka the "Galactus Wave" since each figure came with a piece of the World-destroyer.
Firelord - from the Fantastic Four series 2, fixed his firestaff
Terrax the Tamer - from the Fantastic Four animated series 1, a nice figure of a cool villain
Nova - my 2nd attempt at making her, this is a X-Men Phoenix with light-up-hair attached to a DC Direct Starfire base. I glued bits of translucent orange "flame" plastic to her hair to complete the look. Showed this custom during CustomCon 15 Day 2, along with a few other Fantastic Four related figures.
Morg - started with customizer Johnny Cheung's recipe for this one. Base figure is Bloodhawk from the X-Men 2009 line, milliput armor and details. Hair from Alpha Flight Vindicator ponytail. Wrist armor are accessories from a Spiderman figure and the kneepads come from ninja Sabretooth. Axe is from a McFarlane figure.
I also made a custom of the first herald of Galactus (predating the Surfer), the Fallen. I'd like to eventually show a "wave 2" of him with the rest of the heralds like Red Shift and Stardust.
