Lavos got owned by Magus in the end. And in Symphony of the Night, Alucard took on a lot more powerful enemies than Lavos. Obviously due to Lavos power to have DNA of all living things would clearly make him a bad ass. However if this were indeed true, Chrono Trigger would have been unbeatable. Seems logical, but for some reason I don't see Lavos as an elgible opponent being that he already got owned by one of the aforementioned competitors.
