Champion and their stories

After some thinking, i reached a conclusion, that LoL have three type of champions:

1. Serious champions with serious stories;
2. Not serious champions with serious stories;
3. Serious champions with not serious stories.

All these have one of tho main aspects about them:

1. They are pursuing some kind of enemy, try to get or do something important, protect something or serve some other purpose;
2. They are just having fun.

And all champions have at least one of these secondary aspects:

1. Tragedy;
2. Being rejected, being the last on or being one and only;
3. Need to protect or save something;
4. Need to kill or destroy something, avenge someone;
5. Being lost or misguided;
6. Having a heavy burden;
7. Is crazy, evil or/and wild monster.

To the point of this discussion. I am thinking on making a champion, who would have these features:

1. Serious champion with serious story;
2. He is pursuing some kind of enemy, try to get or do something important, protect something or serve some other purpose;
3. Tragedy;
4. Need to protect or save something;
5. Having a heavy burden. In other words, i am making very serious champion, but there is a catch - i don't want it to look serious at all. Serious champion, but as at the same time not serious.

Any ideas on that?
