From my original K-Phoria stories, King K and his living motorcyle, Cycletariat.
Cycletariat was recently updated and redesigned. Anyway for thos who don't know about him, Cycletariat is King K's loyal motorcycle who is alive and capable of fantastic speed, flight and even dimension jumping. King K often rides Cycletariat into new worlds seeking adventure and meeting new friends.
K-Phoria. It's a bit of what you call "self-insertion" artwork.
