Serious answer? Amber, after Tails' fur color. Or Nikki, after Nicky/Sonic.
Good luck!

Honestly the person Sonic cares the most about is Tails and vice versa you really don't need the other characters

Not to say having more is a bad thing but fundamentally Sonic and Tails is the quintessential character dynamic in the series and nothing comes close

They look so perfect next to each other
