Kroxo is an Alien variant of Croco and is several times stronger. Although he appears to be one of the weakest Alien enemies, he is not much of a threat towards the beginning of Into the Future stages, but in later in the game, he may be strong enough to take out a high leveled Eraser Cat in one hit due to the absurdly high strength magnifications he's given in Cats of the Cosmos and Uncanny Legends. In appearance, Kroxo is identical to Croco, with the significant difference of being colored cyan. His eyes are now sticking out of his head.
The strategy for this enemy varies greatly with its strength magnification. Any peon clearer like Crazed Gross Cat works greatly when this is not buffed, but its damage becomes apparent when it is buffed, requiring units like Macho Leg Cat to quickly kill it, specifically in late-game.
