The second hero of the Algo solar system, Rolf Landale successfully saved the entire system by disabling Mother Brain, freeing the system from it's control.
Also, along the way, he defeated a monster in a box known as Dark Force, one who, in later history, would be known to be more dangerous than Mother Brain herself...
Rolf's fighting strategy largely revolves around one skill: Megid, a massive explosion that can defeat many of his foes in a single blast. However, only a fool would think this is his only skill: Rolf's also a powerful swordsman with strong light techniques, some moderate gravity and wind attacks, and even some healing.
Rolf's Duelling League career has been an interesting one, to say the least: He was defeated by one of the strongest Godlikes in the league, Ghaleon, downgraded to Heavy, and won his way back up to Godlikes, and even later win matches there, a rare feat.
Sadly, though, he then ran into Ghaleon again. Poor bastard.
