Play Ben 10 : Alien Rivals Online

Ben 10: Alien Rivals was part of the Classic Games on Mobile lineup, a release that brought the series to phones during a time when character based action games were common. It was developed and published by GameLoft, a familiar name from that mobile era.

You control Ben Tennyson, cycling through his alien forms like Heatblast and Stinkfly to battle a series of alien rivals. The main objective is to defeat each opponent in one on one combat across different arenas. Signature mechanics include a simple control scheme for attacks and special moves, along with a health and energy management system that forces you to time your transformations. The pacing is quick, with matches that are short but can be surprisingly difficult, demanding you learn each alien's specific strengths. It feels like a straightforward portable fighter that captures the simple fun of the cartoon.
