10 Impossible Video Games Bosses You Totally Underestimated

10. Fire Dragon - Chrono Cross

One of six elemental dragons encountered during Chrono Cross, the Fire Dragon is, unlike his siblings, just a little guy. He stands a little bit shorter than average human height and he has just the cutest little dragon baby face.

The first time you fight this little guy, he's no pushover, but he's far from the worst. He'll attack you with fire - you know, as dragons do - and you'll attack him with water and ice. It's a challenging encounter, but nothing you wouldn't be prepared for.

So the next time you fight him, you're probably expecting a more difficult version of the same battle. And for a few rounds, that's exactly what you get.

Queue his transformation into something that can best be described as the love child of a dragon and a Gundam. And just to drive the point home, he's covered in huge spikes. This fiery colossus has a standard fire breath attack that hits the whole party, and an even more powerful Inferno attack that easily has the potential to one-shot your entire party, depending on level and equipment.

Just keep that Heal All spell handy.
