I dunno maybe adapt the whole kang thing?

As of right now, it'd be better to focus on Harley, since they already have him around. They should focus on the characters they have a work to strongly develop those, so that we can see the influence Tony has had on him, which I think would be far more touching.

@Brett3801 I second that. Harley was such a good influence on Tony, though. He helped make Tony into who he was.

Isn’t Nathaniel Richards Kang the conqueror?

^ yes, an alternate, future version of him. The younger version of him becomes Iron Lad to stop his future self and to prevent himself from becoming Kang.

I definitely know who Harley is, but who is nate?

Nate is technically Harley in the comics

They are not the same person but they are similar they both help our Ironman from time to time and the both eventually get there own suits. If you count rumors for Harley keener

Talking of Harley, what happened to him after Stark donated the potato gun v2?
