Warrior of Nature is the 1st stage in Street Fighter.
Blanka is the only enemy that appears in this stage and does not appear until the enemy base is hit.
Since this is the first stage, Blanka is much weaker than normal and should not be regarded as a threat. Blanka gets knockbacked about every single hit he takes. The best optimal strategy is rush the base with (preferably) a cow/giraffe cat to get the all the rewards. Even just a lvl 1 cow cat works.
At the start of the battle, a Squire Rel will spawn right away, followed by another Squire Rel and a Kang Roo 4 secs later, as well as a third and final Squire Rel following shortly after. No more enemies will spawn after the third Squire Rel spawns.
- Boss Wave
Once the base's health hits 99% and below, Blanka (Enemy) and Dhalsim (Enemy) will spawn, along with a Kang Roo and a Squire Rel. A few Squire Rel and Kang Roo will spawn throughout the battle after the boss wave.
A strategy you can do at the start is kill the Squire Rel and stall the Kang Roo if you are not going for rewards. Since no enemies spawn after the third Squire Rel, this could help you prepare for the boss wave.
When you are ready to attack, send 1 cat that can hit the base and act as bait, do not spawn any meatshields yet. Then when the boss wave is activated, let them kill the cat and lure Blanka (Enemy) to your base. Once Blanka is close, summon some meatshields, lvl 20 Wall cats are enough, then summon all your other cats and kill Blanka. If you cannot kill Blanka before Dhalsim (Enemy) gets there then Dhalsim will make it a bit harder since he can weaken your cats. Try to kill the Kang Roos for money and you should be alright once both Blanka and Dhalsim are dead. Note: You can also just attack them head on. (removing the luring part) This is also a viable strategy.
Cats that can outrange Blanka and Dhalsim like Lizard Cat (Normal Cat) and Bahamut Cat (Special Cat) are useful when trying to beat the stage. You can also try to spam giraffe cats if they are high enough lvl. Treasures also help.
