RWBY vs My Hero Academia
Connection:
Both are high-ranking, dark skinned female combatants of their respective Fighter-consisting Organizations. (Ace Ops and Pro Heroes respectively)
Both share a loud & overly active nature alongside an inherent connection to the fighting spirit of things ,as well as to combat as a whole
Both come from a world with an inherent ability system (Semblances and Quirks respectively)
Both their lax & cocky personality at many points is subverted by their full-most dedication to managing the key resolve at hand when such a notable issue comes to be, dedicating themselves through even massive harms and restraints if it means getting the job done on their part
Both their stubbornness can be seen in how they act, however, even with their arms compromised, both women have fought on with every other faculty possible at hand! (Harriet failing to ever stop fighting when quite literally having her hands tied behind her back against Ruby and Mirko fighting on hordes at top speed, even with a completely busted arm)
Both possess fantastic close-combat capabilities and superbly enhanced movement & leg usability alike (Harriet's Super-Speed & Mirko's massive leg enhancements)
Both specific abilities are also quite well-connected through their similar rabbit inspired origins
Both are known to pursue solo skirmishes despite having a synergize with other groups (Harriet often splitting off to manage tasks she deems necessary personally, in spite of her remarkable synergy with the Ace Ops and Miruko being notable as one of the highest ranking Heroes despite being one of the sole characters of such status to not host a corporation or team at hand to assist)
Both are also voiced by the same English actor, Anairis Quinones
