In Fighting Warriors
In Fighting Warriors he was a fighter that you could unlock by doing Arcade Mode with Kenshin Alef (Alef's Clone). In this game he was ranked 2nd in the Dragon Quest Playful Warriors list due to his really good speed and very good attacks, however one flaw is that his recovery is not that good.
In Allys Assemble
Blade was one of the returning veterans for Allys Assemble. this time he can be unlocked by doing Dragon Quest Missions #69 with Kenshin Alef which take a bit long to get to 69. This Time he is ranked the 10th in the list because despite being more faster then he was his attacks were not as powerful as they were and his recovery is still the worst.
He will appear in the upcoming Dragon Quest Fighting Warriors: Villain Power.
