Hello! As I was passing my time on Random battles I came across a situation
Thing is I got really confused by it, might be my ignorance on pokemon but here's the case
Kingler (Life orb) against a Venonat (Black Sludge)
1st turn we substitute
2nd turn Venonat Quiver dances and Kingler uses Return with common recoil from life orb, getting rid of Venonat's sub
3rd turn Venonat uses bug buzz and debilitated Kingler bypassing the Kingler sub that was still up
Did this happen because one of Venonat's abilities? Or was it the Life Orb recoil that caused that? Since I have never catched one I don't know what they do could somebody help me clear this up?
