The second girl in Tails' harem. I have always seen Marine as Blaze's Tails, even with Blaze's connection to Cream in Rush. Plus, there are a few Tails X Marine fanfics and fan art.

Not sure if anyone notices or acknowledges, but Marine's dialogue is unique. For example, instead of "Hello" she says " 'ello". That's my attend at accent for Marine.

Pre-dating Marine is a bit controlling and acts like a bold captain most. While she is shyer than Tails, she does a better job of hiding it. Marine is more the same when dating, minus the shyness. The shyness has dropped, and she is more risky regarding lewd moments with Tails. (The one thing she got from Blaze.)
