Inspired by a song, how would you build this character?

[Douche]

The song is called Duke Lion by a band called BigDumbFace

Spoiler: Lyrics

Show

He's the Son of Man and God and lion
He's the one who keeps the good from dyin'
We've seen the rest, he is the best
He's the best and his name is Duke Lion

His golden sword can shoot out balls of fire
His special armor makes him never tire
His magical arrows fly like sparrows
He fights for good for free, he's not for hire

A bolt of lightning from the sky, Duke Lion
Where there is battle he will fly, Duke Lion
He's never late, he's super great
He's here to stay, so let us thank Duke Lion

Here he comes to save the day, Duke Lion
He will make the villains pay, Duke Lion
His golden sword will crush the hoard
He's here to stay, so let us thank Duke Lion

He's the son of man and God and lion
He's the one who keeps the good from dyin'
We've see the rest, 'cause he is the best
He's the best and his name is Duke Lion

Including magic items - what build, and what is the minimum level that you can accomplish all these feats.

Reads like maybe a celestial warlock to me. Maybe with some sorcerer tossed in.
