How to Evolve Units in Multiverse Tower Defense

Evolution transforms base units into advanced forms with higher stats, new passives, and sometimes altered attack patterns. In Multiverse Tower Defense, the Evolve building in the lobby handles all evolution transactions. Not every unit has an evolution path — Commons typically cap without evolution, while Epics and Legendaries often unlock powerful tier jumps like Black Leg evolving into Black Leg (Hotter Flames) with burn damage.

Each evolution demands specific materials: duplicate copies of the base unit, evolution stones from Raid drops, and Cash fees scaling with rarity. Before evolving, confirm the result appears in our A-tier rankings — some evolutions move units multiple tier positions and justify the material cost immediately.

Farm evolution materials efficiently through Raid mode rather than story replays. Raids drop concentrated reward tables including universe-specific evolution tokens during events. The Undertale Raid during the current event cycle offers themed materials alongside Undertale Crates from codes like UNDERTALE and 2K_LIKES_UNDERTALE.

Evolve your primary carry first. Spreading materials across six mediocre units creates a weaker account than two fully evolved anchors. If Doughking or Legendary God sits in your roster, prioritize their evolution paths before cosmetic upgrades or Trading Plaza purchases.

Evolved units synergize with enchant rerolls — a burn-evolved Black Leg benefits from Power enchants while range-focused units like Red Warrior pair with Range or Eternal enchants. Read our enchant guide after evolving to maximize the stat spike.

Track evolution progress in the unit collection menu. Locked evolutions show material requirements grayed out until you meet thresholds. Cross-link with fusion mechanics because some players confuse fuse stat boosts with evolution transformations — they are separate systems serving different progression goals.
