Canterlot Troubles

Lord Shen has been entrusted to watch over Canterlot by Celestia and Luna while they attend to an impourent meeting with Saddle Arabia. Lord Shen expected to look at a realitivly peaceful, and boring day. Alot of their enemies, the villain teams including, are inactive, and the lougers are extremely busy with an extended peace mission that Shen is not really that much good in. He actselly wouldn't mind if Icky and Iago were to suddenly appear. However, he does get an unwanted surprise of a truely more bad veriatity: Two Kung Fu Warriors who still hold a grudge against Shen named Ging Mu and Ying Dong, two Ox brothers who hated Shen for what he did in the past, and sought to finally make him pay for his crimes, and care not who they hurt in their wake. Can Shen be able to get himself out of this predicerment without Equestia or Canterot getting hurt?
