Punchline is a humanoid transformation with a collapsible dark purple shell on his head, chest, and waist. He has four eyes and possesses rubber hose cartoon-like features with his four long elastic arms and his lanky, light purple body. His hands and feet are a lighter purple and resemble gloves and boots.
The Omnitrix symbol is located on his chest.
- Elastic Body- Punchline has a very flexible and elastic body, able to stretch up to 500 feet while also being durable enough to not have his limbs ripped off while applying force from such distances.
- Soundproof Shell- Punchline has a light, soundproof shell that protects him from minor damage.
- Moldable Appendages- Fists and feet are composed of a honey-like substance akin to blood or nutrients. This allows him to mold and harden his hands and feet into a specific shape. These can be broken off without harm.
- Limited Attention Span- While in this form, Ben can be easily distracted and forgets his current objective the instant he sees anything interesting.
- Limbs- Punchline has no fine control over his limbs when they are thrown out. This can cause unnecessary damage to his surroundings.
- Shell- While his shell can sustain certain amounts of damage, his shell is more so used by his species as a way of shutting out their visual and audial stimuli, allowing them to sleep. Therefore, it is best not to utilize his shell for defensive purposes.
The Elongasai are well known for their enthusiastic nature, sporadic movements, and their hard-hitting punches and kicks. This leads to them exerting themselves in games with other alien species, such as: Atrocians, Squirtizans, and especially other Elongasai. Despite not wanting to cause harm, their lack of self-control leads to others being harmed or their property being destroyed.
Originally from Prodive III, they have since been relocated the local planet known as Sprungia covered under the Prodive Treaty. The planet is full of dense rainforest, home to creatures that are sufficiently resistant or immune to physical trauma. This allows the Elongasai to play freely without needing to worry about the safety of others. However, they tend to annoy their more mellow neighbors with their hyper-activity.
- The Elongasai used to live on the same world as the Squirtizan.
