You know what? This is the first season where we haven't seen any main girl Digimon! Season 2 had Gatomon, a carryover at least. This season, they're leaving us guys in the dust...guess they'll surprise us with the fourth main Digimon (he wasn't revealed until later in the form of Falcomon for Season 5 so I assume we'll see the new one later). The best Digimon by far this season looks to be Dorurumon. Looking like Tiger from Monster Rancher is a plus for me. He was awesome.
Ballistamon: Shoutmon's partner... or rather, a wife-like Digimon who couldn't leave Shoutmon well enough alone and ended up sticking by his side. With its overwhelming power and armor, it becomes the group's shield. An honest warrior who never speaks a word. On very good terms with Taiki, Akari, and Zenjiro.
It still does not say if this is a female character, though the wife-like part implies that...could this be our "main girl". If so color me disappointed. Hopefully they will drop something Rosemon-chest epic later on.
Believe in yourself! Not you who believe in me, not me, who believes in you.
Okay, look at this trailer and you will cameos from your favorite Digimon! This implies that we'll see them as part of the main character's army! At least, perhaps, we'll see them fight!
