Your quirk was... powerful. To say the least. Or should I say quirks? Yeah. You had multiple quirks fused into one. You could control fire, water, earth and air. But it had been dubbed 'Elements'. There was a fifth Element... but it was darkness and... you didn't tend to use that much. As it was the part you couldn't really control well and if it got out of hand... it was bad. So you'd been temporarily banned from using Darkness unless your teacher Aizawa was around, so he could get rid of your quirk just in case. But it was only temporary until you could control darkness. You were allowed to use the rest of the elements by yourself though, so it was alright.

You were training at the moment. With the rest of the Bakusquad (yes you were in the Bakusquad) but you were in the corner and trying to control multiple elements at once. It was tricky but you were determined to master it.
