Eve's real name is an acronym that Shockwave gave her. E.V.A. — Enhanced Visual Android. Shockwave has been trying to create the perfect bot since Soundwave found out about his pregnancy, so when Eve was in the forge, her father modified her code in every way, sometimes lie to Soundwave by saying that it was a normal medical examination.
Soundwave hated the nickname Shockwave often called his daughter, so he made up his own nickname and only called his daughter by it and as often as possible. E.V.A. — Everlasting Vocal Angel. Soundwave loves his little angel.
Because of these modifications, she was born very early, and in addition, Eve simply does not have a voice box, she cannot literally speak, so she learned to communicate with sign language and signals. In addition to normal hand gestures, she uses Soundwave's internal frequencies. She can transmit her thoughts directly to her father in the form of a code or display holographic text through her third eye. By the way, this third eye is also a modification of Shockwave, this third eye is able to see through walls, notice invisible enemies and calculate the trajectories of shots faster than any supercomputer.
When it became clear about this experiment, Soundwave forbade Shockwave to even approach her daughter, and Eve herself hates her father and what he did to her, so she ignores him, and if he tries to talk to her, she flies away or pushes him away with her tentacles.
When Eve grew up, her spark demanded the appearance of a new cassette, Soundwave, having consulted with her daughter, immediately installed a blocker for her, because Shockwave was already planning to use her daughter's genes to create an entire army like her. And to save her daughter, Soundwave gave her to the care of Ratbat, who became her partner.
She has a great relationship with her brother Rumble and sister Frenzy, the three of them always got into trouble, even pouring a can of paint instead of gasoline into Nemesis, which caused the engine to burn out. Ravage, on the contrary, considers Eve her daughter, not Soundwave's, so she often washed her and taught her her habits.
During her absence, Eve met Stardrop and quickly became friends, and have already become partners. Eve hates Octantis the most, because she believed that he was the reason that Megatron left the Decepticons, and in the sign language she called him "a bastard". But more than Octantis, she hates Bluesun, namely her illogical actions and "too suspiciously good attitude" towards everyone. She hates Kreida because she exists, and she also gets incredible pleasure from fighting the twins because she often wins.
