As you are now,

So once was I.

As I am now,

So you will be.

So prepare unto fangirling,

And follow me.

There was was a fellow named Loki,

His villainy was definitely hokey,

His costume's a joke,

(he's really a nice bloke)

And his talents lean more towards karaoke.

Old Batsy is a hero no doubt,

His punches pack quite a clout,

But when it comes to the job,

There's no one like Rob,

And the hero is worse off without!
