I think you are asking the wrong people OP. Do you have any friends with 7 to 10 year old kids?
If I'm thinking of the toys a young ASaiyan would want, the words that stand out are "cool" and "fun to play with". So, in the first place, characters that look really badass - buff dudes with angry eyes, maybe those skull balaclavas and sunglasses like that character Ghost (That's CoD, right? Make a Ghost toy.), riding in badass vehicles like tanks all painted up and attack helicopters with oversized guns. The villains can be equally buff, bald angry Russians with piercing blue eyes and highly Russian names, because Cold War era stereotypes is still the villain angle CoD uses, I think. (On that note, the heroes should have 'cool-sounding' American names, like "MacGuyver", "Johnson", "Perez", "Wong", etc.)
Secondly, in order to have fun playing with them and making up your own adventures, the toys have to be functional. I'm talking movable joints and swappable weapons for the characters, moving wheels on the tanks, a spinnable helicopter rotor, etc. Maybe make a playset with one or two stock buildings in it too.
Top it all off with the ad: 30 second spots on Cartoon Network weekend mornings. A deep-voiced narrator talking about how cool the toys are over a ripping guitar track with too much bass. Shots of actual kids playing with the toys and having a good time spliced with footage of gruff looking soldier actors, rolling tanks and taking-off military planes that probably overglamorize war.
There's my pitch. I'm a fellow businessman, but not a consultant, so you can have any of those ideas for free, lol.
