Differences

 * Ultimate Spider-Man relies less on team-ups and focuses more on Peter dealing with working on a team while facing several rogues directly connected to his mythos, being more akin to the comics and previous television incarnations.
 * In addition, Peter's personality is more akin to other media, being less jerkish and somewhat dumb and more geeky and friendly.
 * The fourth-wall breaking scenes don't exist at all as a way to keep a more serious take.
 * Far more characters appear.
 * The infamous crossover with Jessie would never happen.
