- Energy Absorption- Amalgaman is able to absorb different types of energy and can redirect it.
- Matter Absorption- Amalgaman is able to absorb matter and create a coating of it around his body. He can then shapeshift parts of his body into different objects such as weapons and constructs that he can detach from his body. He is able to absorb organic and inorganic matter.
- DNA Absorption- Amalgaman is able to absorb the DNA of others and morph parts of his body to match the absorbed DNA.
- Enhanced Physiology- Amalgaman has a physiology greater than that of a human including strength, durability, speed and endurance. When absorbing matter or DNA, he can increase his physiology's capabilities further.
- Over Absorption- Amalgaman can absorb too much energy, which can lead to addiction.
- DNA Absorption Limit- Amalgaman is not able to absorb the full capabilities of the DNA they absorb, only able to have around 10% of their original power.
- Omnitrix DNA- Amalgaman cannot absorb DNA in the Omnitrix. This is due to it being his own DNA, thus cancelling out the absorption. He is reliant on absorbing other's DNA to gain extra abilities.
