The series will be feature wriing by Ian Flynn, David Williams, & Gary Martin and artwork by Kelsey Shannon, David Williams, Gary Martin, and Jack Morelli.
Here is how ARCHIE SUPERTEENS VS. CRUSADERS #1 is described in the solicits:
Riverdale High’s new substitute teacher is very odd. Snubbed by the scientific community, he plans his revenge—on the students of Riverdale High! It’s going to take a team of people with some mighty powers to stop him. Archie Comics’ two most renowned superhero teams are going to meet up for the first time ever in this special mini-series! Features cover 1 of 2 special connecting main covers!Issue #1 is scheduled for publication on 06/20/18.
Incidentally, I learned indirectly that MIGHTY CRUSADERS will be ending next month with Issue #4. Maybe this is what Archie Comics should do more often: 1-3 issue mini-series that start and end quickly and concisely.
