I don't know what his name is, but he's shown up a few times. He looks similar to Flash Sentry so I like to think they are brothers.
About his name, it appears that the fandom has already come up with the name "First Base"
I'm pretty sure he's second base. At least that's what I've heard in a comic.
Awwwwww it's so cute !!!!!! Oh and his name is First Base.^^
I HAVE A NAME FOR HIM: Lighting Ball (u like?)
all we need now is the mommy & daddy

This is one of the best pics of him and First Base I've seen yet!

Flash Sentry's little bro is more or less First Base so it's appropriate.
Yeah - I love this head canon too
