Midsummer: [grumble] I guess so. But how was this creature a threat to anyone? He's not that hard to catch nor is he very cunning.
Toxic: Oi, I'm right here! Don't be so rude~
I chose to start with my Sol boys capturing the elusive Toxic Love for the first time. Mids and Tides aren't the most social guards in the castle of friendship but they are the most efficient. If you need a job done, they are the best choice if you want it done quick. Their teamwork is second to none and they are very skilled in their field.
Hence, when they were asked to investigate the mysterious robberies of shiny objects occurring in Ponyville, they were shocked to find the culprit was a Changeling. A prince on top of it all. It was confusing to say the least but the brother did their jobs, locking him away for a long time.
Or really, just an hour or so.
Toxic is very good at slipping away, making an escape in mere minutes. While impressed that he'd escaped so easily, the brothers weren't willing to give up.
Note: I haven't drawn Toxic in a million years so let me re-introduce him. He's the son of Queen Chrysalis and the recently released from her 2d prison, Mane-iac. He takes after them both, acting as a sort of phantom thief that uses his abilities to rob and steal what he likes. He was, at one point in time, friends with Prince Sirius Veil until the prince cut ties with him.
