Tigrex's weakness is thunder, so try to get an electric weapon. And since his attacks have no elemental attribute, you want an armor with a high raw defense. (unless you fight it in the mountains. in that case the attack where he launches rocks at you has an ice attribute so wear armor with good ice resistance)
