After the monsters have been freed from the Underground, they've been excited to explore the surface. However, no one expects what happens.

After Starlight has been reformed, she's been hanging out with the Mane 6. But Pinkie has been shaking, her Pinkie Sense telling her that something big is going to happen. But nopony expected monsters.

Undertale/MLP crossover. Pacifist Chara. No goat child (sorry). Mettaton is in this because we need fabulous robot. Papyrus can't handle anymore puns.

The follow-up to "Harmonic Spectrum."

It has been quite some time since Rainbow Dash, who had discovered her true destiny as the long-lost Flame of Harmony, saved Equestria from the clutches of the Spirit of Chaos, Discord. Ever since that incident, Dash has been training herself in order to better understand her power as the Flame of Harmony, otherwise known as her Super form.

Now, an ancient enemy, one that the princesses had defeated long ago, returns. Lord Tirek is once again out in the wild, stealing magic from the pony population wherever he goes. And not even the princesses themselves, including Twilight Sparkle, can stand up to his might.

When all else fails, when all hope is lost, only the mighty scream of the heroic Flame of Harmony, Super Rainbow Dash, can save them all.

Little did she know, however, that a mysterious, otherworldly being is aiding and watching Tirek from the shadows...

A crossover with... I'll let you guess on that.

The main theme of this fic is "HERO ~Song of Hope~" from Dragon Ball Z: Battle of Gods.

Super Rainbow Dash concept and design by me. Conceptualized in the summer of 2011, pre-dating Hasbro's Rainbow Power forms.
