I was thinking that Discord can join my Roary and Theodore's Adventures team. Because in "Twilight's Kingdom Part 2", Discord is himself betrayed by Tirek and drained of his powers. It is ultimately Discord who helps Twilight discover her key by giving her a trinket that Tirek had previously given him, which Tirek had previously received from his brother Srorpan. He then truly reforms at last, having realized the true importance of friendship. At the end of the episode, he is accepted by the other ponies and is seen celebrating with them before offering a bouquet of flowers to Celestia and winking at her.

See?
