Koa, First Tree of Equilor
Pronouns: He/him or they/them, but they really aren’t too picky
Age: Unfathomably old - several million years old at least.
First Planeswalk: Unknown
Colors: White/Black/Green.
Appearance (and/or Art): When he is mobile, he appears as he does on his card (see below). When rooted, he appears as a massive oak tree. Any attempt to cut him down adds a nice shade of red to his color scheme.
Backstory: On the plane of Equilor, a plane so old that it took Urza Planeswalker a hundred years to planeswalk there and a hundred years back, a plane so old they started searching for enlightenment seventy five thousand years before Nicol Bolas was even born, a plane so old the mountains have been worn down by time, Koa was the very first tree. Being connected so deeply with the plane (as there were no other trees to take away from the connection) gave Koa a measure of sentience. Soon saplings grew up around him. But when a magical fire threatened to burn away Koa and all his “children”, his latent planeswalker spark ignited and threw Koa to a nearby plane, becoming the first treefolk of Equilor in the process.
Magic, gear and/or abilities: As Koa possesses an incalculable number of lifetimes’ worth of knowledge (see Other), Koa is essentially unfazed by any attempt to actually harm him. Especially since the Mending (which Koa was sleeping through - see Other) there is very little magic that could actually hurt him or kill him, at least not permanently. Koa also maintains a psychic connection with all his past bodies throughout the multiverse (Other), obtaining a steady stream of knowledge from them.
Other: Whenever Koa visits a new world, he spends a few years mobile before rooting himself into the plane. He stays there for a thousand years, connecting deeply with the plane’s Worldsoul. Then the great oak tree produces a sapling, which becomes Koa’s new body and inherits his planeswalker spark.
