Gran Slam Champions
Someone is considered Gran Slam Champion if they win the World Speedrunning Championship, the International King of Crass Championship and the Intercontinental Duos Championship.
Only 2 people have been able to do so:
- Kolapro by winning the WSC in WCC2, winning the IKCC vs Cotote in a tie-breaker match and then winning the IDC with Italisian in DBD2.
- Italisian by winning the IDC with DarkLizzard in DBD1, winning the IKCC vs Kolapro in a championship match and then winning the WSC in RRBO.
- Italisian is also considered as the only triple champion as he held all 3 titles at the same time.
