Sonic and rwby worlds combined

Chapter 8: Super vs dark forms. Infinite last stand.

When the two teams got their strength back they knew they had to deal with this "girls you take on the grimm, leave Infinite to us" Tails said "No way we can-" "your still tried the most you'll do is get in the way" Shadow said and then "Nora smash" Nora appeared as Team jnpr then team cfvy with professor port and professor Obblect (with Zewi) and glynda, with team KRAB but the guys saw that Jaune accidentally drop the SEVEN CHAOS EMERALD "Shadow quick" Sonic shouted but just the guy were about to grab them Metal Sonic appeared and pushed them back while throwing the Emerald at infinite "Like I said this will be your grave" Infinite said the used them and transformed into Super Infinite

And his mask was removed but as Shadow went to removed his inhibitor rings and charged but...

'Smirk'

Infinite landed a solid hit on Shadow in the stomach and he fell to fool in unquestionable pain he was struggling to sit up "Shadow!" Blake shouted "Blake stay back! Your mine Infinite!" Sonic said while using a homing attack on him but Infinite stopped him and grabbed by his leg and smashed him down on the ground multiple times until it got to the point that sonic in the same amount of pain that shadow was in "SONIC/BRO!" everyone shouted in shock then Infinite hovered in the air and posed like a divine god "no one can touch me. With the power of the Phantom Ruby and seven Chaos emeralds power I have surpassed the gods themselves" Infinite spoke until he saw Blake and Ruby helping sonic and shadow "those two foolish children will die and their blood will stain the ground" Infinite said and got ready but two red light form around Sonic and shadow making the girls back away until as the light died down.

Sonic and Shadow were standing with their fur's changed Sonic was Dark blue and Shadow was red as their auras formed around their bodies with their colour changes.

"I'LL LET NEVER YOU LAY A FINGER ON BLAKE/RUBY". Shadow and Sonic shouted at Infinite "Guys I thought we agreed never to use those powers again?!" Tails said "Sorry little bro but I've had it with Infinite" Sonic said while powering up "what the hell! W-what kind of power is this" Infinite said in fear feeling the air pressure change around him, from the guys aura's "Your going straight to hell" Shadow said then the two Hedgehog got ready, they rushed towards Infinite and overpowered him, Shadow grabbed hold of his face and smashed it against the ground then, he then let go of his face as Infinite stumble to stand up. Sonic then appeared in front of him and gave him an upper cut. Not only forcing the Emeralds to leave Infinite but also smashing the Phantom Ruby, as it shattered into thousands of pieces. Infinite fell and landed on his back groaning in pain and agony trying to recover his senses but was in too much pain, all of a sudden he looked to see both sonic and shadow too tired causing them to return to normal.

"GUYS!!" everyone shouted, "You should have finished me when you had the chance" Infinite said getting up however he was stopped and found himself surrounded by Cyan aura he looked to see Silver was holding him still with psychokinesis "your right this is your end" Tails said "NOW TAILS" Silver shouted as tails charged his arm cannon "GOODBYE INFINITE, full power chaos beam" Tails said and a beam of chaos shot out of the cannon and Infinite was turned to dust all that was left was his mask "hehe well looks like this was his last stand" Shadow said with a smirk as he and sonic was struggling to stand then Blake and Ruby help them stand "well done hedgehog" everyone saw Metal Sonic.

Who appeared in front of Sonic and Shadow "if you hearing this then I'm surprised that you defeated Infinite, but do let it go to your head now that I'm with MY new partner and I will crush you and build my empire" the message ended and metal used Shadow copies ability to use Chaos Control to teleport away. After getting rid of the remaining grim, Team SSST and Team Rwby were at the beacon sitting edge and looking at the ships around Vale and thanks to silver they still had the chaos emeralds "Sonic, Shadow what happened to you two?" Weiss asked "we have dark forms they appear when either me or Shadow completely lose control of our tempers and just had enough but Shadow need to remove his inhibitor rings and my body was beaten up after Infinite attacks" Sonic explained and they notice that Ozpin was behind them and he thanked the two team for taking on the Grimm and Infinite for good, "I suggest training for the tournament but I think we've got that covered" Weiss said "So time for bed" Ruby suggested "yes please ''''Absolutely" "I'm gonna sleep forever" Girls said then they turn to see the boys "you guys coming?" Yang asked as the guys nodded then got up and went with Girls to get some well deserved sleep.
