Captain Marvel vs. Captain Marvel

Since I was a kid I always wonder if there will be cross overs about characters with similar name or powers between different comic book companies. Since I never got to see Aquaman vs. Namor, Quicksilver vs. The Flash and so forth, I thought it would be a great idea to make up my own version and have some fun drawing cool characters.
I even thought it would make a great comic book line. It could be named Crossover Battles Presents...of course you would have to deal with an extensive amount of work from licensing. But it would be a new an original source of work for everyone in the business (writers, artists, editors, etc). I think the most fun part was coming up with the battles matches, I got 67 so far.
I know I should be working on Terranova, my Sci Fi epic film. But I got very enthusiastic about drawing characters that remind me of my happy childhood. Every once in a while it's very healthy for an artist to draw for fun and not for a work related project.
I hope you like my first one, there's still some work to be done but I think it's OK to post.
Captain Marvel from DC comics was created in 1939 by artist C. C. Beck and writer Bill Parker, the character first appeared in Whiz Comics #2 (February 1940). With a premise that taps adolescent fantasy, Captain Marvel is the alter ego of Billy Batson, a youth who works as a radio news reporter and was chosen to be a champion of good by the wizard Shazam.
Captain Marvel from Marvel comics is the name of several superheroes appearing in comic books published by Marvel Comics. Most of these versions exist in Marvel's main shared universe, known as the Marvel Universe. It's almost like a title.
I chose Khn'nr the most recent one, an alien character who has appeared in numerous comic book series published by Marvel. He is a Skrull sleeper agent posing as the Kree Captain Mar-Vell aka Captain Marvel.
The shapeshifting Skrull Khn'nr was bonded with the DNA of Mar-Vell to lock his body into Mar-Vell's form and given technological replicas of the Kree Nega-Bands. However, his mental conditioning was botched, causing Khn'nr's personality to be erased leaving the Mar-Vell persona dominant. Though part of the Skrull invasion of Earth, this Captain Marvel decides to fight against the invading Skrulls.
