Manfred (a.k.a Manny) was once a grumpy and unsociable mammoth, suffering from the loss of his family who were hunted down my humans. Instead of following the migration like everyone else, he preferred instead to walk against the current and go in the opposite direction. However, despite his attitude, Manfred has a heart and does not hesitate to fight to save the live of Sid, from whom he follows the mammoth.

Upon meeting Diego, Manny did not trust Diego, but knew that to get rid of the sloth and the baby, they must be guided through the mountains by him. Brave and courageous, he did not hesitate to risk his life to save Diego, eventually inviting the sabre-tooth cat as a "member of his clan."

In the second movie, he is believed to be the last of his kind, until he managed to find Ellie, the love of his life. Now in a family once again, he will do the best to protect them. He is very attached to his clan and not afraid of anything, not even sea monsters or dinosaurs!

In third film, he and Ellie are preparing for the birth of their child, calling it by the name of the ”code”, Peaches. Very protective and attentive, and even preparing his child a playground before it comes into the world, he will prove to be not only a caring father, but also a loyal and courageous friend to his pack.
