Hawkeye's name can be seen on one of the news tickers, mentioning him cutting the ribbon to the bald eagle exhibit.
Hawkeye makes a full appearance when he was summoned by Nick Fury to protect Spider-Man from the revenge-hungry Beetle and help him to take him down if necessary, much to the web-head's annoyance. Despite their arguments and differences in their battle, they managed to stop Beetle.
Hawkeye appears in the series as a member of the new team of Avengers. He still retains his confident attitude, but sports an attire resembling his film counterpart, as well as purple shades. He is first contacted by Iron Man right after he stopped Trapster and two other villains from committing a robbery.
