It all started when he was just a furling. Of course, he still IS a furling since he's a baby Digimon but I mean a long time ago when he was FIRST Babumon. When Babumon digivolves to Motimon, Tentomon, Kabuterimon or Megakabuterimon, he's a good guy. But when he's Babumon, he's evil and wants to control the weather.

It's kind of sad though, because if he wanted to control the weather when he's Megakabuterimon...well...he probably wouldn't be able to do it. But if he wanted to control anything else then I'd let him because he's a gigantic bug. But since it's BABUMON who wants to control the weather, nobody's really afraid of him.

If you look at Babumon while he's saying BA-A-BUMON!! BA-A-BUMON!! Then you would just look at him with a strange expression and back away slowly. Because he sounds like he's derranged.

Babumon vowed that he would control the weather, someday, somehow. He wants to get revenge. Don't ask for what...he just does. Let's hope that Babumon never figures out how to control the weather or we'll be in big ca-ca!!!!
