"Why protect the fragile balance and peace when you can break it yourself and put a stronger balance in its place?" ― Cardo telling Pinakamataas his goal
Cardo Dalisay is a powerful mammoth and was the antagonist of The Iron Gods saga for chapters 10-26, making him the longest running villain in the series, with a total of 16 chapters (excluding Himagsikan, who was more of a "behind the shadows" villain since Chapter 7). While he was in a vegetative state during the end of 10 to the end of 13, his dark magical influence did affect the course of all that happened around him.
He would be the main cause for The Flash War upon his rise to godhood and his trickery of sealing away Penduko. He would be "killed" by the assassin Placido Penitente during his asylum in The Northern World/Galaxy.
In reality however his soul was merely severed from his body and trapped in the mirror dimension. When the omniverse would be reset by Sakramentong Alak and Tagapagligtas, his spirit would still live on slumbering and now trapped in the Macrocosmal Wall until he would eventually re-awaken and return in Chapter 81, 55 chapters later.
