ben 10 - mc donald's happy meal

When 10-year-old Ben Tennyson doscovers a mysterious device, he gains the power to change into 10 diffrent alien heroes.

From McDonald's Happy Meal, here are four of the aliens.

Diamondhead is a crystalline alien whose body is harder than diamond, making him invulnerable to most physical attacks and allowing him to cut and slash through almost anything. He can also use his body to reflect light and beam based weapons.Whenever Ben needs to smash, throw or beat up something, Fourarms is the hero at choices. Standing twelve feet tall, this formidable four-armed alien can use his tremendous strength to dish out the punishment, while his armored skin protects him from harm.A living machine with liquid metallic skin, Upgrade is a biomechanical alien that can merge with any mechanical device, from a blender to a bicycle to a satellite. While merged, he can "upgrade' the device into an incredible piece of Ultra-Tech far more advanced than any existing Earth technology.Heatblast comes from an alien race that lives on a sun rather than a planet. He can project bolts of fire from his hands and mouth and create fireballs he can throw or roll. He can also absorbs both flames and heat, meaning he can put out a fire just as quick as he can start one.
