I may be confusing with another unvierse or other male character, but i could sworn is aw mr fanastic as tall and wide as a building once.
Spiderfolk, like other examples, would still be related in some way. I can see this as one of the reasons they decided to change.Even then who cares if the powers are similar, it's their background and personalities that make them unique. That's why we can have so many different Spidermen running around.
Honestly, i think the way they look in the series more unique
