If a Bulldoze crits 1 Pokemon, it has the normal 1/16 (gens 1 through 6) chance to crit and the 1/24 chance to crit (since gen 7 and beyond currently).

In this replay, my Hydreigon crits his Meowscarada and Appletun on Turn 2 but doesn't crit his Sandaconda.
On Turn 4, my Hydreigon only crits the Sandaconda but not the other Pokemon. However, with guaranteed crit chance (Focus Energy plus Scope Lens), AOE attacks always crit all Mons that it hits, as shown on Turn 3 where I crit all Pokemon on the field. Thanks for RisingManectric for helping with testing.
