What kind of cultural differences? I've never heard of the United Federation of Planets, but it sounds similar to the Nova Corps. The only Terran I knew before coming here was my friend Peter. He goes by Star-Lord. My friend Groot is a Floral Colossus, Gamora is a Zen-Whoberis. Nebula was a Luphomoid but now she's mostly a cyborg. She has blue skin too!
I don't know, but she can put things inside herself to keep them safe.
