Alien superhero princess
Gameplay and story are completely different. If they gave some random Goomba in TTYD 5000 HP that wouldn't make it any more powerful story wise just a heck of a challenge to beat gameplay wise. Similarly if the Shadow Queen were easy that wouldn't make her not a near invulnerably almighty demon who can enslave the world on her own.I'd believe that if super dimentio weren't such a weak boss. I mean all it does is try to step on you or shoot easily dodged blocks.
Just because a boss fight is easy doesn't mean the character is weak or vice versa.
