Stronius was an elite Skrall and favourite servant of Tuma, also known as "Tumour". Stronius was a very controversial character, known for whacking random Skrall on the head with his giant club for no good reason.

He is also pretty stout, to which the Glatorian ridiculed him for during the Core War. However, he bashed their heads in so bad they were the ones turned into dwarves. One of them is known as Telluris.

He also met a Baterra once, who just starting doing the 'Robot' and singing 'Mr Roboto'. Stronius was bored of this spectacle and whacked it in the back, destroying it.
