Sequoiamon is a Mega-class Human Hybrid Digimon whose name is derived from Sequoia and Sequoioideae, a type of tree, also signifies her elemental power. She is one of the Elemental Gods, specifically the Goddess of Wood, created by King Royalmon as well as Queen Majestymon, the parents of Prince Signamon.
She was the first of the Elemental Gods to be created along with Tundramon, Cobaltmon and Brightmon before the exile of the Royal Family to the Dark Area. It's been said that Royalmon copied the data of AncientTroiamon, without the latter's knowledge during Galenemon and Passiomon's coronation to celebrate them reaching Ultimate Level.. When the royal family was banished to the Dark Area, she served as the bodyguard and trained under Lucemon Chaos Mode, one of the Seven Great Demon Lords. She wears two necklaces one with the Crest of Sincerity the other with the symbol representing the Spirits of Wood, which were given to her by Majestymon. Along with Aquamon and Blazemon, she was modeled after Empressmon, Majestymon's original and purified form. Unlike the other two, she doesn't vie for the approval and attention of Prince Signamon, instead she treats him as her equal. Her completion is said to have a more greener and browner tint to it, differentiating her from the other two. Having been influenced by not only the royal family, but by Lucemon Chaos Mode, Sequoiamon often captures Digimon who have darkness in their hearts for the purpose of destroying them or influencing them to stay in the Dark Area. It's said that Sequoiamon, Aquamon and Blazemon are counterparts of one another and have similar attacks, in both Human form and Beast form. Her outfit resembles that of the one worn by Poison Ivy in the Batman comics.
