Shattered Hearts: Encounter of Worlds with Twisted Times

It's Our Return: One For All and Explosion on Green Hill and Earth

After Sonic, Tails, Spectrum and Nine finished... their "supposed trip" to Deku's universe, they arrived at Green Hill and not at Unified Grim!

Nine: WTF? We're supposed to arrive at our place not yours! - frowned Nine.

Tails: Nine's right. Why we're here on Green Hill instead? - strangely asked Tails.

Sonic: *sees one of his Warp Rings broken* Hehehe... I think this is the case! One of my Warp Rings is broken.

Spectrum: How many Warp Rings you've stashed on? - Spectrum angrily asked Sonic very impatient.

Sonic: A dozen... maybe fifteen of them.

Spectrum: You brought all of those Warp Rings, without proper checking and maintenance and ONE OF THEM WAS BROKEN AND WENT HAYWIRE!?! 

Spectrum maybe doesn't have an an IQ of 300 or high tech expertise like Tails and Nine, but is a very perceptive and intelligent hedgehog when it comes in anticipation and keen intuition in both battle and support. Unfortunally, this was their bad lucky day!

Nine: WHAT!? No wonder our jump through that universe went all loopy! Now we need to fix everything about the universal transporter. - Nine was aggravated by Sonic's foolishness.

Tails: *sighs* Sonic...

Sonic: What? I thought it was necessary in cases of emergency! - Sonic responded back.

Tails: Don't you think that we also used the Time Stones in our inter-dimensional travel? - said Tails with frustration.

A Ring Portal opened above them, dropping down from the sky Izuku Midoriya and Katsuki Bakugo! The two of them fall down to the ground, but remained unscathed from the impact by using their Quirks.

Nine: Of course they HAD TO SHOW UP WHERE! - Nine said that with anger, glaring at Sonic.

Deku: Kacchan... I think we aren't on our world! - Deku said in bewilderement.

Tails: Now you're in OUR WORLD! Well... only a bit of it.

Bakugo: WTF IS THIS PLACE!?!? It looks like a Photoshop coloured fever dream!

Deku: Please, there's no need to insult them! - he said in a scary manner.

Never... but never say that in front of Sonic!

Sonic: You take that back, exploding boy! - Sonic was insulted by Bakugo's remark and retorted to him.

Bakugo: Of course! This must be the home of you furries. - he said furiously.

Spectrum: *eyes twitching with rage* Is their "vacation" permanent, Tails? You know about Sonic's Warp Rings more than us.

Tails: *looked at the broken Warp Ring* It will take a while to repair it. Please Nine... can I need your help with this, if you don't mind? - begged Tails for asking Nine's assistance.

Nine: *smirked* Sure, why not?

Deku: So... we're stuck here? - asked in fear.

Sonic: In the meantime... how about a sparring session you two? - asked Sonic to Deku and Bakugo.

Spectrum: You're right! I still have a score to settle against him. - Spectrum said that as he pointed at Bakugo.

Bakugo: Hell yeah! Time to kick some butt.

Spectrum: It's yours that will get kicked out when I win!

Deku: Don't you think it's a bad idea causing too many explosions here?

Bakugo: SHUT UP, YOU DAMN NERD!

Green Hill could be permanently burned to a crisp if they use too much of their fire power in a battle at a large scale.
