Ever since the original Ben 10 series, Four Arms has been one of Ben’s favorite aliens. His immense strength lets him pick up almost anything and use it as a weapon, and he can create a massive shockwave by clapping his four hands together. He’s also tough and durable, able to withstand a lot of punishment in a fight.
Here’s Four Arms in his original incarnation, when 10-year-old Ben Tennyson first started using him.
In Ben 10 Ultimate Alien, Four Arms got a makeover, giving him more of a gladiator/warrior kind of look.
And in Ben 10 Omniverse, Four Arms got updated again, resulting in the awesome design he has now.
