This is the fourth 'Canadian Shield' superhero character I know of. I understand the term lends itself very well to the whole nationalist/heroic milieu, but jeesh!Lol...Well, I have to come clean and admit that when I created my own little group as a hobby as a kid, that was one of the first names that came to mind too. It's just such a great name! And surely no one else has though of it! Then you do a quick Google search and what do you know...
Just for kicks, let's check out some of the other characters using the name. Aside from NAQ's mentioned earlier, we'll skip the Heroes of the North version as he has been pointed out before. Many of these are created for use in role-playing games and such, not necessarily for a comic book.
This one is by Darren Calvert.
"I did this piece a while back as a follow up to an illustration I did for the Golden Age Mutants & Masterminds sourcebook. He was part of a group of multinational WWII-era heroes I created for the illustration. I decided to go for a more traditional style with a pencil drawing overlaid with muted watercolors.
The world needs more heroes with mustaches."
Ain't THAT the truth, brother...
The next one is by someone who only refers to himself as "Agent Foo" or "The Foo" on deviantart. Pretty classic look.
Then we have this guy:
Canadian Shield is a real life hero whose mission is to inform public, especially children of how to avoid potentially violent situations including being bullied, but also illustrating other POSITIVE LIFESTYLE CHOICES. To this end he makes appearances around the city and has released a comic book reflecting these messages. Ask for promotional material at COVER to COVER and GALAXY comics.Got to respect the effort there.
Lastly, the Canadian Shield name is used for an entire team, at times.
Inferno. Hunter. Surefire. Brutus. Airstrike. Northwind. Zenith. Gathered to keep the True North Strong and Free, they are the first - and usually last - line of defense for Arctic sovereignty. They are the Canadian Shield.
