Well, that varies a lot. Different fanfiction writers handle Ben's injuries differently. Some might put him in dangerous situations often, resulting in multiple injuries. Others might focus more on his victories and minimize the harm he takes.
Big Ben is reckoned to be around 96 stories tall. This includes the base, clock faces, and the spire. The height is quite impressive and makes it a notable landmark.
In the 'Ben 10' series, Ben Tennyson is the main character. He has a device called the Omnitrix which allows him to transform into various alien forms. Gwen Tennyson is Ben's cousin. She also has magical abilities and often teams up with Ben in their adventures.
Ben 110 can be developed by giving him new challenges related to the Highbreed. For example, he could face a Highbreed villain who has a power that nullifies Ben's alien forms. This would force him to rely on his human intelligence and resourcefulness. He could also develop his character by learning about the Highbreed's language and communication methods, which would show his adaptability.
In one adventure, Ben and Gwen had to deal with a group of shape - shifting aliens. Ben's ability to transform into different aliens was put to the test as he had to constantly adapt to the changing forms of the enemies. Gwen used her magic to detect the true forms of the aliens. They combined their skills, Ben's physical combat skills as different aliens and Gwen's magic detection and support, to defeat the group and save the day.
