Dilemma of Being a Story Maker

Establishing the Kind of Story!

Easy, an awesome adventure story that's really cool. 

Just, I dunno if I want it to be serious and dramatic with some comedy mixed in that'll draw the reader in and have them become emotionally attached to the characters and world, or a massive joke that'll make people laugh and smile but still feel some attachment to the characters... I mean both are pretty good in their own ways... I'll go ahead and pitch two plots for each of these ideas:

Serious Adventure: 

1. Main character with giant bird friend go on an epic adventure where the meet new faces, new places, and find themselves to the task of choosing whether to save the world, or let it burn.

2. Main character is an villain that is tricked into becoming an good guy and has to both learn how to coordinate with his colleagues throughout a series of events.

Not-so-Serious Adventure: 

1. What could basically be a Bo-Bobo spinoff, a lousy hero and his friends are tasked with not only saving the world, but getting revenge for his ruined childhood.

2. In a fusion of plot 2 from "Serious Adventure" and plot 1 of "Not-so-Serious Adventure", after a shocking fake out, a villain becomes the main character, but is forced to become the hero when the spotlight points to him.
