The Alien Hero of the Underground (Ben 10 X Undertale)

The Finale: Part 2

Frisk and Chara stand before Asriel Dreemurr, and they are very nervous.

Frisk presses ACT, and she picks Check on Asriel.

* ASRIEL DREEMURR ATK ♾️ DEF ♾️
* Legendary being made of every SOUL in the Underground.

Frisk: "That is terrifying!"

Chara: "Keep your wits about you!" She puts her ghostly hands on Frisk's shoulders. "We'll find a way to win, like always!"

The attack starts, and it is a tornado of fireballs that head towards Frisk. Frisk is able to weave between each attack with ease.

After the end of that attack, Frisk opens ACT and presses Hope.

* You held onto your hopes....
* You reduced how much DAMAGE you'll take this turn!

Frisk: "Yes!"

Chara: "Let's go!"

The same attack as before, and Frisk avoids it all the same. However, towards the end, a bright light blinds Frisk and Chara. When the light dissipates, Asriel is floating around the area in the shape of an Infinity, and the entire area around them becomes very colorful.

* "The true final battle" was finally beginning.

Frisk: 'This looks bad.' She opens ACT. 'But I have to push through it.'

Frisk presses Dream in the ACT menu.

* You think about why you're here now...
* You can feel the empty space in your inventory get smaller and smaller!

Chara: "Yes! More healing items!"

An attack begins, and Asriel raises his arms up high, multi-colored stars appearing around them, before disappearing.

Then a dozen of those multi-colored stars, but much larger, rain down and hit the border of the attack zone. When they make contact, they explode into tinier stars, which Frisk has to weave through.

There is then one last star, one much larger than the previous one. It slowly falls down and hits the border, exploding into several dozen tiny stars. Luckily for Frisk, she is able to dodge them. Albeit, with some difficulty.

* Asriel charges "SHOCKER BREAKER."

Frisk: "That sounds powerful."

Chara: "I'm sure you'll be fine."

Frisk opens ACT, presses Hope.

* You kept holding on.
* DAMAGE reduced!

Asriel: "You know, I don't care about destroying this world anymore."

Asriel holds his arms up, rainbow electricity emanating from them, before he disappears.

After Asriel disappears, red squares with exclamation points appear in the battle area. They appear every other space, and Frisk happened to be on one of the empty spaces.

In the spots with boxes, a rainbow-colored lightning strike comes down. Then the boxes appear in the empty spots this time, forcing Frisk to move out of the way. This happens a couple more times.

Then, two large boxes take up the battle area, and Frisk races to reach the empty spot. But she is unable to make it, and is shocked. Then there were three boxes, but Frisk was standing in an open area, leaving her unharmed from the second wave. The attack then ends.

Frisk HP: 17/20.

* Asriel calls on "CHAOS SABER."

Chara: "You alright, Frisk?"
