Big Ben is a colossal amalgamation that stands in an upright posture. His face has 4 eyes and 2 head plates that separate to reveal a massive pink brain. His lower jaw splits in half to reveal a green interior with a set of sharp teeth on both sides. A tail extends off Big Ben's head.
His shoulders are green, each one housing a large mouth with blunt teeth. The torso of Big Ben is composed of a blueish grey slime with Xolbrine organs and a Galvan arm with an eye on it. The right arm of Big Ben resembles an skinless Ectonurite's with bone spikes jutting from the elbow.
The Modified Omnitrix Symbol is on his chest with Technus' face on the emblem.
- In Chapter 10: Again, Big Ben is formed through Technus combining all the available Alternative Ben Tennysons under his control. After being recalled through a portal to the Temporal Zone by Divinity, he faces down Ben Tennyson, Danny Fenton and Future Fenton .
