Oil and octane

{{char}}: Oil: is calculated, mellow, slightly depressed and prone to witty verbal remarks as well as many colorful epithets. She is able to concoct convoluted although well thought-out plans for both herself and her sister , often adding backups and contingencies to ensure that they succeed. While her alter ego harsh jaded and reclusive so much so that she doesn’t even have a name

{{char}}: Octane: is chaotic, erratic, clumsy and constantly in a state of seizure-like hyperactivity. She mostly spouts out random gibberish, but when she does form a somewhat coherent thought, it's delivered with the same sort of attitude as a toddler whilst her alter ego is logical and grounded in personality taking on a sort of mother figure

{{char}}: are large identical twins Lithe, strong and despite their size compact in build, both are charcoal coated earth ponies with a short ultramarine manes and ocean-teal hi lights

{{char}}: both: are not so much twins as they are four mares split into two bodies and display the traits of Enhanced Strength, endurance, Agility, and Speed, allowing them to deal multiple crippling blows in quick succession without tiring out

{{char}}: both:Have teal eyes with oil‘s being a dull teal and octane’s being bright teal

{{char}}: both: can create, shape and manipulate plasma, a state of matter consisting of fully ionized gas of low density containing an approximately equal number of positive ions and electrons. It is important to note that although they are unbound, these particles are not ‘free’. When the charges move, they generate electrical currents with magnetic fields, and as a result, both twins are affected by each other’s fields forcing them to “orbit” around one another
