6. TENTOMON
This ladybug-like Digimon is Tentomon, a smart and curious creature belonging to Izzy, an intelligent but antisocial boy. Tentomon helps his geeky companion to become a more social person and assists him with opening up. He is the first Digimon to have a deeper relationship with his partner, which grants him a higher ranking on this list, despite being ugly as hell. After all, he is a bug, and there’s nothing pretty about that.
What’s neat about him, though, are his electric powers, which are already more useful than anything Palmon or Biyomon can do. However, his more powerful forms, Kabuterimon and MegaKabuterimon, are also hideous. There’s even a bigger problem with him: when Tentomon talks, his mouth doesn’t move. That’s definitely weird.
