[DC] How to Convince Everyone I'm Not the Leader of the League of Assassins

Batman’s greatest enemy. The Demon's Head. Ra's al Ghul. Leader of the League of Assassins. Keeper of the Lazarus Pit. Damian's maternal grandfather. He is dead!

Everyone is convinced of it, including Ra's al Ghul himself...

My name is Erikson Lind. At least, that's what I'm called now.

I thought I was a helpless, pitiful, powerless eight-year-old with amnesia.

But when I moved to Gotham with my adoptive father, a group of people "informed" me that I was actually the "former" leader of the League of Assassins. I'd lived for centuries, and I had two daughters and a grandson?!

What kind of nonsense is this?!

I woke up with amnesia, and my grandson is older than I am...

Don't worry, everyone. I won't do anything illegal! I'm just an eight-year-old kid! I don't know anything, and I can't do anything!! So could you please stop handcuffing me? My adoptive parents will worry, and I have school tomorrow. It's my first day!!! Please let me go!!!!

This story touches on a few other universes, such as Marvel and some sci-fi series (special mentions go to Spider-Man, Deadpool, and Stranger Things).

The protagonist is Damian's maternal grandfather... I was a little curious about Ra's, so I looked into his origins... Before I knew it, I kind of fell for what he was like before he turned evil... He was a kind and righteous doctor in his early years! And he had a super beautiful wife! Oh my god!!!
