Spider-Man/Deadpool: My Two Dads

It's the Planet of the 'Pools! What dark technology from the secret recesses of S.H.I.E.L.D. history powers these L.M.D.-eadpools? To defeat the Faux-pool who took his ability to walk, Old Man Parker will have to make a decision that alters his future and our present! And how were Mary and Richard Parker, AKA The Amazing Spider-Parents, involved? Just when you thought you could trust that two people were without blemish, Deadpool somehow ruins them, too.
