In short a cross-over between Spider-Girl, the Young Allies and Avengers Academy Annuals. Reminds me of those cross-overs from the late 80's/early 90's and honestly would be happy if those type of cross-overs/events became the norm again.
He last showed up during the Divided We Stand X-Factor arc right? I hope he is back to his over the top self, I remember he had a more muted style there. I hope the White Rabbit is there too, I think they are a good couple.
