Let me preface by saying I understand the concept difference between the 2. Spider-man can't fly and Iron Man can't wall crawl. It's unclear to me if there is any game mechanic difference between flight and wall crawler. If I understand the rules, when a character with either of these powers advances over a terrain feature they use the range tool appropriate for their movement profile and are considered size 5. Is there any difference in these 2 powers other than the names? Thanks for any help
