First, you need to “make” a Bug-Vorah build. To do so, from the main menu, choose Kutomize, Characters, D’Vorah then select any of the available slots that already have a build in them such as 1. Buzzing Hive
From here, press R1 / RB twice to go to the Abilities tab, uncheck the Deadly Swarm and (Air) Ticking Time Bug abilities then head to the last Ability which is the Mother-Bug. Ensure you check this Ability, back out to the main menu then go into a standard fight (Fight, Local) and select D’vorah ensuring you choose the build with the Mother-Bug ability assigned to it (1. Buzzing Hive if you followed the steps), put the game on any difficulty you’re happy with, very easy is fine and begin the match
Now for this one (using default settings) you will need to win the first round, lose the second round then in the third round, get your opponent down to Kritical health (around 3-5mm) and allow the opponent to beat you where Bug-Vorah will burst out of D’vorah.
Please Note ~ Your opponents finishing blow must come from a standard attack, a throw or a special will not count and you will need to do the process again
