Doctor Who?

A traveler in space and time. 
With this blue box of mine. 
The adventures sometimes covered in grime. 
Righting wrongs a thin line. 

My companions are plenty. 
Unique and bold. 
Aged to nine hundred and twenty. 
Looking at new and old. 

Come tell me your flavor. 
The future or the past. 
As you here the engines quiver. 
You relies your about to have a blast. 

Pond saved me on her wedding day. 
Something old something new something borrowed and something blue. 
Her daughter River to stray. 
Passing through time to become my glue. 

I witnessed the death of a many thing. 
Even the impossible planet. 
And an unspeakable king.
As a black hole swallows the granite. 

I concord the Daleks. 
In the time war. 
But it caused conflicts. 
Lone survivor the time lords are no more. 

Smaller on the outside. 
And huge within. 
Come along for a ride. 
And enjoy its spin. 

Simply known as the doctor. 
Because of all I do. 
The deciding factor. 
A universal glue.
