Who's best to counter the updated map 6 Bishop mini-boss?

Griffen

Curious who I should use as counter for Bishop mini-boss on map 6. I used to use Doom, but I'm guessing that won't work anymore because of the energy damage from his shock. Thanks for your ideas.

Duped Ultron is a really good option.
