Not magic. Supernatural, but not magic--a distinction the fandom refuses to acknowledge.
i find the aesthetics of supernatural abilities tend to edge far too close to magical end of the scale than the extraordinary end to want martials to be consistently using them as their baseline, if i were to try assign references to the various descriptors and my justifications of their positions (using MCU as i feel that's a fairly common reference point), in DnD i'd want my martials floating around hawkeye-to-extraordinary at lower levels and enhanced-to-hulk at higher ones.
Full Magic Aesthetic - Dr Strange (spell circles and somantic gestures, energy blasts, manipulating forces of reality)
- Scarlet Witch (below Strange due to more freeform casting)
Supernatural - Thor (flight, producing lightning, superfast healing,(yes i realise some of this is a byproduct of moljnir/stormbreaker but i'm considering them as one for the example))
- Hulk (visible transformation, superhuman strength and toughness but no 'powers' per se)
Enhanced - Spider-man (beyond human strength, supersenses, quickened healing, wallcrawling as a
supernatural extrapolation of an ordinary skill)
- Daredevil (supersenses, increased spatial awareness, lie detecting)
Extraordinary - Bucky Barnes (notably enhanced physical ability)
- Hawkeye (supposedly 'perfect' aim with ranged weapons)
Full Martial Aesthetic - Cap America ('peak human' physical conditioning)
some elaboration: daredevil beats out the physically stronger bucky due to possessing senses not found in baseline humans but hulk beats out spider-man who possesses more of those 'unnatural abilities' due to the sheer scale of his power and the transformation aspect from banner to hulk.
