There can be a fine line between inspiration and theft. Okay -- maybe not a fine one. It can be pretty thick, actually -- but we'll say it can be adjusted based on the clout and execution of it's practitioner. It's been my opinion that through Invincible, Robert Kirkman, Cory Walker and Ryan Ottley became masters of this. From the word go, you can rack up a number of comparatives, and by the time we got to that pivotal twelfth issue (where the entire story dynamic got a kick in the pants), the list of homages and lifts ran a gamut of comic icons:
Invincible = Superboy
Omni-Man = Superman
Teen Team = Teen Titans
Guardians of the Globe = Justice League of America (Complete with analogues!)
Darkwing = Batman
Red Rush = Flash
War Woman = Wonder Woman
Aquarus = Aqua Man
Green Ghost = Green Lantern
Martian Man = Martian Manhunter
The character list goes on and on, and even the names of the story-arcs are references to classic and current television sitcoms (Family Matters, Eight is Enough, Friends, & Modern Family...just to name a few).
So, it should be no question that Kirkman & Co inspired some...(ahem) repetition of their own. When Invincible first graced the newsstand, I was just getting it into my heart and mind that my lifelong pursuit of being a comic book artist was OVER. Instead, I wanted to be a writer, turning my vocabulary of "if-then" equations and scaled conflicts into stories that anyone else might like to read. Finding Invincible, when I did, may have been vital to me writing, not only today -- but at all! It's kind of humbling to look at it that way, and still quite inspiring all the same.
Entering the HOTSHOT Era:

At any rate, after MONTHS of toiling on it, quitting at least once when it felt like there were too many OTHER cooks in the kitchen, I handed in a treatment for the first five issues of an arc called Hero's Welcome (now available for purchase in tpb!). I can honestly say that at the time, I don't THINK I specifically used Invincible as the basis (in fact, the character comparison I wrote put him up against Spider-man...who Invincible teamed up with in 2006), but looking back all these years later (and doing some side by sides...), Kirkman's hand was all up the skirt of my writing ideas...wait, that sounded crude. My bad.
But it's there!
For the sake of not belittling my own career, I'll call it a creative simpatico! But from how we told stories (both series start in the midst of an action sequence, then flashback, taking literal issues to build to that initial moment), to our character portrayals and storylines (critical event caused the death/disappearance of the major hero group) -- there we were following in the footsteps of who we considered (and to a big degree, still do), the BEST superhero comic makers in the game.

We wanted to earn their level so badly...that we incurred the wrath of Savage Dragon creator (and then Image Publisher), Erik Larsen, with our Dare To Compare Challenge*! The whole experience was as uplifting, as it was humbling. And while Robert, nor Ryan never made any mention of it, Cory Walker had kind things to say about our effort and drive.

As harsh as that may sound, he was 100% correct. We weren't. Not even close. We were neophytes at best, throwing stones at a giant. But...you don't get better by playing against people at or below your own level. We wanted to rise, so we challenged who we thought was THE BEST, hoping that our follow up (Dare to Share), would provide us with some clues, insights, if not mentors, for how to make our work eventually get there.
Together, Mike and I did some great work. And while our partnership didn't last, our friendship and brotherhood has. Definitely check out Hotshot and the rest of the Hotshot Universe titles, now published through Legacy
