No, Starstorm isn't really a mother to that tiny robot. That tiny robot just looks up to her as its mother figure. And it's giving Starstorm a gift for Mother's Day...and what could be better than an Energon Harvester? (since that's what that's supposed to be lol)

The mini robot is named Boomer. It doesn't talk so no one really knows its 'gender.'
