(Okay so for this chapter,I kinda felt like maybe now I should probably present some of my characters multiple different forms and techniques related to it,including some that I have been considering on giving them later down the line,Originally I planned to do something like this back when I began to make this book with my main oc(s) Zeke Muto/Renegade,However I think I'm going to save their's for now and start with one of my other primary ocs,This being my oc version of Shadow The Hedgehog,Nitro Salazar)

Chaos Berserker Prestige/Limit Breaker (This technique would have been first used by Nitro and Turbo's father which actually had a connection to the powers or chaos and it can be used on at least a few of the two brothers forms but can only be used when gathering up a good amount of Chaos energy either from the surrounding area or from the Master Emerald ad this technique increases their strength and speed exponentially to about 45%-60% ,however Chaos Berserker Prestige which is Nitro's father's version of Chaos Limit Breaker which Nitro inherited,would ended up putting more of a strain on his body if he uses it for too long)

Super Shadow Form (Chaos Berserker Prestige can be used to give this form a boost in strength,reflexes,agility and speed)

Werehog Form/Chaos Fang (The werehog form for Nitro is what his true appearance would be,well kind off as this form was result or not only his semblance but the also inheriting this form and genetics from his mother's side of the family,This form gives Nitro primal like instincts as it also improves his sense of smell and sight,however his speed would decrease gradually whenever in this form and to make up for it,his arms would be able to strecth out a lot more further than before as he can use them to grab and attack enemies who are further away from him or to traverse areas as it was like a grapple gun,while also gaining sharp claws as well, Thie form is technically always active for Nitro but only appears with the shift in abilities and personality at night time but only if his power limiter rings are off of his wrist,Chaos Berseker Presige is able to be toppled over this form)

Darkspine Form (Nitro's Darkspine form works more as a contrast to his younger brother's dark/EXE forms as while Nitro may be filled with anger and rage when using this form but unlike his brother,Is actually in full control of his emotions and actions along with having the ability to slow down  in the same that Chaos Control would when using one of the seven Chaos Emeralds ,however he is not full control of how to use all of the power he commands in this form,especially if his anger were to get the best of him,Chaos Berserker Prestige can be toppled over this form)

Wrathful Black Mist (Nitro's Wrathful Black Mist form is a fusion between the two iterations of his base form (His human/faunus form and his Werehog form),along with using a merged version of the power from his Chaos Limit Breaker and his Super Shadow Form as he regains his speed and momentum along with the majority of his Chaos Powers,however he loses his stretchy arm ability from the Werehog Form but still retains the forms retractable claws along with it's primal tactics and instincts while still having his original state of mind in this form)

Geneon Chaos Control (Nitro would have obtained access to this form when trying on the outer reach of Angel Island as he was trying to push himself further past his limits when training along a person who was guarding the Island who goes by the name of Jak Vargas (My version of Knuckles The Echinda ) as he was trying to teach him in the ways of suppressing his rage and power and instead letting a more calm and proactive state of mind to flow when in the center of battle,This form cannot be toppled with Chaos Berserker Prestige)

Hyper Shadow Form (Both Turbo and Nitro's iterations work more as an amalgamation of Goku's Ultra Instinct from Dragon Ball Super  and Sonic's original Hyper Form from Sonic 3 and Knuckles mixed with the powers of the wisps from Sonic Colors as when Nitro would first tap into the Hyper Form's latent power after many having many experiences from throughout multiple battles,This would first start to appear as his base form but with a blue and sliver colored aura along with sliver colored eyes as his body would move much quicker than he normally could but uses way more stamina than his than his other forms,but as for when gets in contact with the wisps and gets an additional boost from the Master Emerald would give him full access to his thoughts and control of his array of abilities and power,However just like Ultra Instinct,this form can backfire and put alot of strain and pain on his body as it would send a dark purple colored electric shock to his body for when using too much of the power as his body can not handle it all quite just yet,This form also can not be toppled with Chaos Berserker Prestige)
