These are the last issues before Onslaught comes and Marvel fixes the fact that it made Tony a 16-year-old just because they thought it would save sales. The kid is trying to learn to be a super-hero and meeting some of Iron Man’s classic villains, but none of these weak attempts at developing a new character matter because, again, Onslaught is coming.
It does debut a new super-villain gang, Stockpile, and one of these characters appear multiple times. But most do not. The only one who lives beyond Onslaught is Sunstreak.
