I agree with him being Tenma's descendant.

Here is my creepy theory (and trust me, this is SO WEIRD):

Gouenji Masato has a daughter who is this mysterious boys mum....

'''so basically Tenma and Gouenji are related now.. freaky....'''

But I mean c'mon, who else is a prtoagonist and has white hair in this anime?
