I love the archie series but I feel some characters get alot more credibility than other based on how superior and powerful they are in battle or purely competent they are with their abilities.
Tier 0(god tiers)
Superforms, enerjak, hyper forms, adam, mammoth mongul
Tier 1(Super beings)(base wise)
Sonic the Hedgehog-in over all skills with his base skills and has more feats against high performance wins/ties with higher opponents than both of them, like in the megaman team up, for example, he trashed all the robot masters with casual ease while Shadow had trouble with one of them, beat up silver easily without silver reacting in time, he has gone toe to toe with shadow, metal sonic and knuckles and against the former has out paced him most of the time while managing to dodge him casually.
Scourge the Hedgehog- Easily bested every hedgehog he was up against, has been compared to Sonic and Shadow at the same time, has better feats in his base mode than both hedgehog like spindashing the planet. The fact he can out run a angry shadow and escape show hes considerably faster than shadow is like sonic is.
-Dr. Ivo Eggman Robotnik
Shown to counter Sonic easily with his technological prowess. Scaling to Sonic easily makes him feel more a threat than any of contenders below since its proven he can make multiversal weapons like the more genesis wave.
Silver the Hedgehog- Probably all over the Place feat wise but at total hes ends up stronger than sonic, shadow and silver but is written to job alot like shadow. His feats still put him below sonic and scourge because hes more reactive than proactive with his powers in combat and sonic and scourge are superior in thinking on their fest and being faster than faster than thought opponents in combat. Sonic can whoop silver by being to fast for his telekinesis to register. Maybe it depends on how hes written.
Shadow the Hedgehog - We need to get the clear, shadow is weaker in this series than any other series. If his own power is more detrimental than useful to him, than shadow has less power than sonic in chaos power and real cant handle a large reserve like sonic can at his normal state. Shadow extremely powerful but to many characters scale to him in base feat, while shadow struggles against any sonic copy even metal sonic, shadow has difficulty taking out does slower than him like knuckles, omega, napalm man and silver. Shadow using his inhibitor release is just not tangible proof hes superior. He cant control how much power he uses when he releases the power and it becomes a problem with his life then.
Knuckles the Echidna - hes the only character is can think of than can fight all contenders minus scourge in raw combat and hold his own without esoteric powers. Maybe in the previous issues hed best everyone but hes been empowered when he came back to life with sonic getting stronger than him. Hes also weaker than shadow in a melee exchange when shadow is weakened and not fighting at full strength.
