Who is the guy at the end of the Guardians of the Galaxy 2 credits that says "We Are Groot"?

Question

At the end of the credits for Guardians of the Galaxy: Vol. 2, there's a guy that says

"We Are Groot".

Who is he? Actor and/or character would be awesome.

Answer 1

David Hasselhoff

Character

He is mentioned in the movie as Peter's idol and fatherly figure, however he never actually appears as himself. There is a scene though where once Ego gets annoyed at Peter's rejection, he mentions something like:

I chose the appearance that would be best preferred to you. [transforms into David Hasselhoff] Would you have preferred if I looked like this?

[or somesuch]

Anyway, that's the character part. Now for the sick rap (nah forreals, hang in here I'm dead serious)

Music

David Hasselhoff can't be gotten rid of that easily, nope. He's also in the soundtrack too, in the titular song Guardians Inferno ft. David Hasselhoff, where he raps about the Guardians:

We are Groot

The significance of that little segment in the credits is related to the lyrics of the actual song; which says something a little bit like this:

In these times of hardship
Just remember
We
Are
Groot

^{Ok, it goes exactly like that}

This is a callback to the first movie where Groot sacrifices himself to protect the Guardians with a last line of

We are Groot

Amazing right?

Answer 2

David Hasselhoff, actor from Night Rider (Peter's idol):
