There was a lot of controversy about Thunderbolt following Nigeria's quarter-final defeat to Japan on 10 June, 2014, during the 427th Quidditch World Cup. The Nigerian side were riding on Thunderbolt VII, which many experts felt had sacrificed safety for speed. Nigerian Seeker Samuel Equiano's broom was hit by a Bludger, which smashed its tail off. Shortly after the match, unconfirmed rumours stated that a group of Nigerian warlocks were headed for the Thunderbolt HQ.
