Naga invaded Holly and Suezo's village, killing all the inhabitants except Holly and Suezo.
Naga was the fourth of the Big Bad Four to fight the Searchers. After many attempts to kill them failed, the Searchers invaded Naga's castle. Everyone except Genki, Holly, Mocchi, and Suezo was held off by Naga's followers, and the above mentioned four reached Naga's room and fought him. Suezo was able to get a few shots in, but he gained the advantage, overpowering Mocchi's Mocchi Cannon. He then threatened Holly, who held her dagger out to him. Naga revealed to Holly that Moo (who was merged with her father) ordered the attack on her village. As he was about to kill her, Mocchi hit him with a Mocchi Cannon, smashing him through the wall and leaving him hanging onto the edge of the castle. Though Holly, Genki, Mocchi, and (after much reluctance) Suezo attempted to save him, instead he let go and fell to his death.
He came back to life as a mystery disk after Moo was killed, and in Season 3 he was resurrected as a purified monster and fought on Mocchi's team in the tournament, defeating Gali.
