An' here's a short one for ya.
Two people who share the same origin but were never seen.
These are the profiles on...

Silver Spider
Spiderman

Tommy Troy, a little orphan boy,
finds a wondrous thing, a magic ring.
This magic band turns the boy into a man
Who can do anything a spider can.
From climbing walls, and mighty strength,
His spider gun's web can go to any length.
This spider is a force of might and right,
And all evil hides from his goodly light.
With the spider ring, he leaves a mark,
Which brands evil that hides in the dark.
Beware this Silver Spider, this Spiderman.
