A lot of tv shows and games consist the concept of summoner or something similar in it. These characters summons unreal creatures or maybe the undead to fight for them.
I like this kind of battle more than something like a simple battle action between 2 kung fu fighters. Mainly because it's more about the battle between the summoners' mind and strategy rather than fighting actions. It creates more depth into the battle but not just with flares and explosions.
1 of my favourite story that have the similar concept to a summoner is the manga Yu-Gi-Oh. It's a story about players fighting each other with monster trading cards game. The monster aren't exactly real though since they're actually just 3D projection of the card's monster to make the battle seems more intense.
These kind of characters and stories inspired me to a story like this but not exactly the same. As most summoner characters on screen summon other things to fight, like dragons from up the sky or skeletons from another dimension. What I have in mind is the summoners actually summon their something that's inside them rather than something outside. Maybe in a world, people with potential could summon their inner-self or their other personality into a physical form and uses them to do things and even fight or battle. This could be really interesting. Think about it, what if a character that's a total kind and gentle guy summoned his inner-self and turns out it's a psycho and a killer maniac? This kind of story could turn out dark or funny either way!!
