Question:
Although nonexistent and without destruction, he would have big shoes to fill
Answer:
Big Foot, The Giant Step's giant, Invisible guy from Moonside, Mr. Saturn, and Tessie.
Explanation:
Although nonexistent ... he would have big shoes to fill - (Well the answer I was looking for was Big Foot, but apparently it was more vague than I thought.) Big foot: He's not wearing any shoes and has big feet. Giant Step: The giant foot which left the footprint0 is gone/nowhere to be found. Invisible guy: Who knows what he's wearing, and he doesn't exist either. Mr. Saturn: Not wearing any shoes and has big feet. Tessie: Also has huge "feet", no shoes.
and without destruction, - None of these characters attack/destroy anything.
