Well, I've mentioned him enough that you should know him by now, but a proper introduction is long overdue. So without further ado, may I introduce you to the one that made it all happen for our favorite cybernetic tsun-tsun:

Young!Doc: "O-Oh my..... that was a pretty big fall there, are you alright? Here, let me help you up..."

Aww, he was so sweet when he was younger! Must be why he took Nano in without a question. As he got older though.... well let's just say his mid-life crisis was a bit more on the "alternative" side than neccessary XD

Mid-life Crisis!Doc: "Nanohex, what did I tell you about getting home so late? I know you can handle yourself, but you still had me worried! Ah whatever, as long as you're okay I'm fine. On the bright side I just got the new Woodkid album, wanna hear?"

Seriously Doc, what happened... (；一_一) You were supposed the be the adult in that situation remember? Ah whatever, luckily you grew out of that phase and moved on to become quite the sage old man.

Old!Doc: "Come on Nanohex, we've been over this. You are a grown woman now, you can't just sit down here and tinker all day. And no, you can't help me with my invention before you ask. I need my piece and you need to go outside and make friends!"
