Astonishing Spider-Man vol.7 #36
Marvel Collectors' Edition
The effects of the split of Peter Parker's personality are becoming more evident: while the latter still has his sense of responasibility, Spider-Man has lost it. Proof of this is the fact that it has transformed the Tri-Sentinel into a Spider-bot and by using it in the fighting it has caused numerous damages. Worse still, the mouse on which the same procedure was tested died of the effects of the split. It turns out that it was Mendel Stromm who unleashed the Tri-Sentinel, and a mysterious entity procures him more.
