Mega-blackhole
A blackhole that's larger than average, but not as large as a supermassive one, (aka. an intermediate blackhole).
'Two average-sized blackholes merged to form one so extraordinarily large that it became a mega-blackhole (Nickname: 'The Mega'), but even that is nothing compared to the size of a supermassive blackhole.'
