Shadow is cold and fierce always talking coldy to everyone and staying quiet most the times he still thinks Sonic as reckless and not a good fighter and how they always fight but he still helps them fight but he dosnet always spring into action fast like Sonic but he is still very strong and wont hesitate to fight someone if he needs to.

Sonic is very energetic and reckless of course because he always is, stepping into fights before others and taking risks while he can to svae his friends and spring into action but he still loves teasing Shadow with their friends and enimes/ rivals relationship.

Tails is the smart friend he always thinks before battles and makes the gadgets to use to help everyone but he still steps in to help when he can even though hes young and not as strong as the others.

Knuckles is very fierce and talks about how hes 100% muscle and stuff but he wont stop to defend his friends but he still has a rivalry to Shadow about whos stronger and he still dosent know much about Aaliyah because she works with Eggman.

After Shadow choosing to work with Sonic over him Eggman has found someone else to work with and to manipulate just like he did with Shadow and using Aaliyah's past trauma as a weakness to manipulate her and use her, and Eggman has found Aaliyah very useful to her being stronger then Shadow and Sonic and everyone else and using her as an advantage and to try and destory Sonic, Shadow, Tails and Knuckles.
