One pal. Every branch that leads to it.
Search a target pal, then click "Show parents" on any node to expand that branch further — up to three generations back.
Search for a pal above to start building its tree.
Each branch shows the closest rank-matched pair (or the fixed combo / same-species pairing, when one exists) — not the only way to reach that pal. There are usually several near-equivalent pairings at any given rank; this tree shows you the most direct one per branch.
