Terrakion is a Rock & Fighting type, is another of the Swords of Justice legendary trio & to me has the best design from the Swords of Justice legendaries. As well, I find Terrakion the best both for in game (although you don't get it until like end of playthrough) & in competitive, as Terrakion has pretty good stats, a pretty good movepool & then also has alright abilities. So between the trio of Virizion, Cobalion & Terrakion, can easily say that Terrakion is hands down my favorite of the three both in terms of using in battle & in terms of design, so that's why I ranked Terrakion this high, but I think 13th is a good place to take it out now.
