Fan Casting Magma in The New Mutants

Magma (Amara Juliana Olivians Aquilla) hails from the fictional country of Nova Roma ("New Rome"), a colony of the Roman Republic reportedly founded shortly after the death of Julius Caesar in 44 BC. The colony is hidden in the Amazon Rainforests of modern Brazil, and was ruled until recently by the immortal witch Selene. Amara is the daughter of Lucius Antonius Aquilla. He was presumably a member of the historical gens Antonia which claimed descent from Anton, son of Hercules. Growing up in Nova Roma, she had curly blonde hair, and wore a traditional white Roman toga. She has the ability to generate lava and uses the codename Magma.
