Super easy to kill with a Lightning Wyvern as stated before. My addition to the top would be try to bait it to the moat around red ob into the upper falls where the snow and sand meet on the Easter coast. Then they don't run as much.
These guys can be used for soaking up turrets and plants, but remember they destroy metal so why not let your regular Dino's tank most of the damage than use this beast to destroy all the metal structures. They aren't as tanky as they seem.
Make lots of cannon balls Dododex is wrong. Must get full torp to "tame". If you can't trap it place cannon on the side of platform. Also sometimes shots will not register if titan is clipping on terrain.
