Along with X-23 I have a few other figures I'm working on. One of which is updating the DC Multiverse Rebirth Superman.
First I wanted to swap out the head I wasn't crazy about the original head. So I fitted a casting of a Black Lantern Superman head that I got from casting cave some time back. The paint is still a work in progress, but so far I'm liking how it is looking.
Second was a change I wasn't planning on making. I ended up swapping the arms out with the Target exclusive Public Enemies Superman. I was working on customizing the PE Superman, but apparently its plastic degraded and the torso started to crumble. And then I noticed that the blues were pretty close to a perfect match, so now Rebirth Supes has bigger bulkier arms which look better on it to me.
Then I decided to check out the feet to see how they attach. I can't believe that Mattel designed/constructed them so close to the way that Hasbro does their pivoting feet, but they put the peg hole straight down. They were so close to giving us ankle pivots, but goofed it up. I drilled new angled holes in the feet and rounded down the edges some on the ankle pegs a little... Then working ankle pivots.
