Oov and Nada share a special rivalry, the one that exists between Bonjwas. Nada, the original Bonjwa, was cursed against Oov, the new Bonjwa, as per the Bonjwa curse rules. Despite the fact that Nada could never beat Oov, their games were always epic.
Their first major confrontation occurred in Trigem MSL Loser Bracket Finals. Oov entered as the large underdog against the seasoned veteran Nada. But nevertheless, Oov emerged victorious 3-1. They met again in CenGame MSL Grand Finals. In the last two games of that set, Oov exhibited a strong pressure style - forcibly containing Nada without a care for defense. Nada could not afford the units to shutdown Oov's expos, and Oov eventually ran over him 3-2.
In EVER OSL Nada changed up his game. He changed his ideology from 'one-size fits all' to 'each to his own'. In other words he went from applying the same techniques every game to specializing his strategies for the map he was playing on. The change didn't go according to plan and Nada lost 1-2. Nada was always pushing for a way to beat Oov. At the end of the day Oov was always one step ahead of him. Boxer's training and superior understanding gave Oov the edge over Nada.
Oov and Nada played a number of single matches after EVER. Nada won one of those games, Oov won the other 8. Later Oov would fall victim to the Bonjwa curse against Savior and would feel the same pain that Nada did.
The defining feature of this rivalry is the time span in which it lasted. The two were pioneers of the Terran race and their encounters were always the cutting-edge of contemporary TvT strategy. They played 23 games over a time period of 4 years. Not only that, but many of their encounters were in bo5's. Nada was an ever present opponent during the first half of Oov's reign and helped Oov refine his TvT innovations further. Their games pushed the boundaries of TvT strategy, and their many series forced both players to change and adapt. As a result, TvT strategy advanced considerably.
