Beetle's 13db2,d2 seems like a block infinite on Starfire.
d2 doesn't work, db3 doesn't work, backdash has limited use until the Beetle player adapts.
Please correct me if there are more options I'm missing.
some characters can't backdash it, i know darkseid can't, can't armor either because you'll get busted before you can, you can either try to pushblock or low profile the j2
