She's a buffed Alien Camelle. She can survive a lethal strike, and when her HP reaches 1%, her damage increases by 900%.
In other words, when Alpacky survives a lethal strike (or slightly before), her damage multiplies by 10. Save a damage-dealing Cat Cannon for her lethal strike, use units with longer range than her, or with good timing, fast units will attack her before she can attack them.
Outside of the main chapters, Alpacky has (so far) always appeared at 300% strength magnification.
Camelle super-glued cotton balls to herself to become an Alpaca. Allergic to the fibers, so she can't stop coughing and spitting, but she's too proud to admit when she's wrong.
If you have no units that outrange her, use tanky melee units like Jamiera/Crazed Mythical Titan. Save your Cat Cannon for when she survives the lethal strike. By then, her ability will have activated, and she can deal extreme damage. Use your Cat Cannon to finish her off. However, if you are unlucky, the ability will activate before the lethal strike. If that happens, use units with good speed like Crazed Cow, or even Valkyrie.

This enemy's description says that Alpacky is just Camelle, but also refers to it as "her" (?) while Camelle is a "he."
This unit can be considered a enemy counterpart of Togelan Pasalan; they both survive a lethal strike and greatly increase their attack power when their health is at 1% (however, Shishilan Pasalan increases its power when its HP is below 99%).
