Mareanie evolves into Toxapex. It's a two-stage chain with the method shown below. A massive partner pool for breeding via one egg group. Eggs take an average time to hatch. The evolved forms gain up to 190 total stats over Mareanie. View every chain in the Evolution Chart.
How to Evolve
Breeding

Shiny Mareanie
Mareanie flips from blue-and-purple to a green-and-pink color scheme, and the little starfish predator suddenly looks tropical instead of toxic. The spikes pop differently in the new palette. It's a clean, noticeable change that sets up Toxapex's golden shiny nicely.

We check every game where a shiny is possible, then rank each one by the best method available in that game, so the row at the top is the fastest route overall.
Odds marked verified are cross-checked against multiple independent sources before we publish them. Where a rate is not yet confirmed we mark the row pending rather than guess a number.

Base Stats
Mareanie's stats barely vary. None sit in respectable range with no real gaps. It's a blank slate for EV investment. Worth 1 Defense EV, medium-fast 1M XP curve to max.
It has excellent regenerative capabilities. Legs that a Mareanie has lost have a very bitter, astringent flavor—they’re not suitable as food.
Mareanie Event Distributions
Mareanie is available only through a single Mystery Gift event distribution.
