BRS vs RWBY - Ruby vs Mato

this is an interesting concept, if we are talking OVA or anime BRS, Ruby stands no chance, however, if we play by the scenario presented by your crossover, we have a totally different ball game, Ruby's Scythe along with her speed semblance, create a sticky situation, giving ruby a speed advantage, and a mele advantage as scythe masters (like qrow) can utilize the full potential of such a lethal weapon, the cannon however versatile it may be, is just a large hunk of metal, meaning in a close fight, all it will achieve is creating an opening for Mato's katana, ranged fights however, is Mato's forte, using the cannon, she can put out a volume of fire ruby can only hope to achive with her scythe's sniper capabilities, and the minigun state just takes the cake, now, to win, ruby needs to keep it in a mele fight, because the moment Mato can stun ruby with a shot, it's over, however, I cannot proporly compare as I donnot know what aspects are being taken by dan-heron, meining, I'll leave this as a draw.
