Updated the first post by adding Beelze, BeelzeBM and surprisingly... MirageBM. Can't believe that what i felt about him in F2 that with enhancement, MirageBM can go from hardly usable to usable. Although he can't always skillbreak like Mirage and his AT is about 150 points lower than Mirage (and 3% CT too due to battle type difference) but his F1 + F2 + F1 combo's damage make it for the 2 hit (about 5 seconds) unable to skills, also don't forget that MirageBM is light and he got disadvantage against HiAndromons while Mirage doesn't get any element advantage nor disadvantage, though Mirage is still better since he can kill 1 Data and 3 Vaccines MC6 while his BM can't do that.

So...with this i think it's safe to assume that any BM or side Mega can kill 4 MC 6, orat least Data and Virus one because even the worst BM can do it.... i'll laugh if anyone managed to report that their BM/Side Mega can't kill 4 MC6 with 55 affinity, 2 AT+75 and lv85-90.
