Re: And this is my special eff... er, I mean, my Sidekick.
I had a friend once in the late 80's named Ken Hawkins when I lived in Clarksville, Tenn, whom I used to play Champions with. He was a very creative sort who always had all kinds of great character concepts. One was a character named "Shield" who had an invisible "sidekick" named "Buckler" that only Shield could see. Ken defined "Buckler" as nd6 of Luck (I could be mistaken, but I believe at the time the system limited you to 3d6 of Luck, but I bet if Ken were still active, he would want to add more dice to this).
Shield (and Buckler) was a homage/parody of Captain America (and Bucky), and was a bit of a loon. We (as a group) were never really sure if Buckler was one of Shield's imaginary friends, or if he really existed. Whenever Shield would get lucky in combat, he would always credit Buckler in that typical baritone voice: "Good going, Buckler!" "Nice save, Buckler!" and so on. He was a loon, but fun to be around, plus a very good combatant, so we let him stick around.
Alas, because I moved to New York in the middle of the campaign, I never found out if Buckler was real or not.
