To select the best free Rainbow creature during launch in Aniimo, check the official Japanese wiki (wiki.aniimo.com/ja) to verify currently available event rewards, then choose a single Rainbow unit that counters the dominant elemental types in your starting region.
Checking Active Rainbow Aniimo Distributions
Free Rainbow-tier creatures distributed during service launch can originate from login bonuses, promotional codes, or limited-time launch campaigns. Because reward pools change over time, check the distribution list before finalizing your squad setup:
- Visit the official Japanese wiki resource (
wiki.aniimo.com/ja). - Search for the "Rainbow" attribute or navigate to the campaign/event section to see all currently active promotional codes and log-in rewards.
- Note the elemental type, role, and claim conditions for each available creature.
Selecting Your Early-Game Carry
Because high-tier Rainbow creatures require substantial resources to level up, select one primary Rainbow unit to serve as your main combat carry while building the rest of your squad around it.
- Match Area Weaknesses: Compare available Rainbow elements against the dominant enemy types in your primary exploration area. Choosing a Rainbow creature with type advantage reduces time spent leveling secondary standard units.
- Identify Combat Roles: Strikers are designed for high damage output and breaking enemy combat shields during tough encounters, whereas utility units offer buffs that assist with exploration or base maintenance.
- Conserve Upgrade Resources: Focus your main upgrade materials on your single Rainbow carry. Over-investing in multiple high-tier creatures early on drains resources needed for base facilities and support structures.
Rainbow Selection Decision Checklist
| Factor | Strategic Focus | Recommendation |
|---|---|---|
| Availability | Event/Promo windows | Confirm redemption codes on the official wiki before committing resources. |
| Element | Early zone counter | Pick a type that directly exploits enemy weaknesses in initial zones. |
| Role | Squad synergy | Choose a combat striker if your squad lacks damage, or utility if combat is covered. |
| Resource Plan | Leveling efficiency | Focus investment on one Rainbow carry rather than splitting materials across several. |
