Based on a Halo/Doom crossover pic I found and decided to make a Marathon photoshop pic of.
DOOG SLAYERさまとライオン オ サイボ-ーグさまとネコマタフォンおかゆさまにながいきます！
I hope Korone or Okayu (maybe even both) do Marathon at some point. I asked Korone about that recently (in Japanese, thank you) but I don't expect a reply. She doesn't often reply to people outside of stream chat as far as I know. Crossing what's left of my fingers.
