What are some quirks that synergize well together and would look like one quirk to other people? Like how Deku had originally said that Black Whip was apart of his original quirk rather than a completely different quirk. An example could if Bakugo had Landmine it would just be considered apart of his quirk because it causes explosions of other objects and could be easily believed by the public.
Ignoring any Quirks with direct relations, like the Iidas, the Himuras, or the Todorokis, there's only a handful of options that I think really fits that. At least, not without a lot of stretching of the concepts of one or both Quirks or going for two redundant options, like "Larceny" and "Attraction of Small Objects", "Confession" and "Polygraph", or "Homing" and "Boomerang". And I'll just stick to how you can fenagle them into a single Quirk.
-Black Whip/Rivet Stab: You can control your whips enough to harden them to a rigid point -Arbor/Vines: You have a plant body that you grow and control. You're hair just so happens to be vines. -Larceny/Slide and Glide: You've trained your propulsion enough to be able to attract things as well. -Somnambulist/Sleep Gas: You can push your gas to new heights, but makes it far more toxic. -Transform/Meatball: You can shape your flesh, but need a genetic staple to replicate others. -Softening/Stiffening: You can make things hard or soft instead of only one or the other. -Overlock/High Spec: You're brain is so advanced that you can overload your brain to make yourself faster. -Absorb and Release/Impact Recoil: You can redirect attacks, but it's easiest to do with kinetic energy. Anything else can be dangerous.
