One of my main goals for doing a new ref sheet was also to do a clean version. I've really been wanting to commission a few artists who don't do adult work, and I really didn't want to send them my obviously adult (and frankly out of date) old ref. So I designed both the adult and general versions simultaneously when I updated it.
It's been my head canon for a while now that Pulsar has wings in his SFW form. And even though I've drawn a few pics of him that way, I never really made it "official" until now. So this is the for-real first version of him like this.

Oh that's neat, having different modes for different settings is pretty sensible...
